Nokia 8.3 5G – fit for James Bond

Nokia 8.3 5G – fit for James Bond
4.0Overall Score
Name: Nokia 8.3 5G
Price (RRP): $899
Manufacturer: Nokia

The Nokia 8.3 5G is it’s first 5G foray and anything good enough for James and friends is good enough for me.

But damn you, Nokia. Your Nokia 8.3 5G ‘No Time to Die’ promo ‘in cinemas November 2020’ got me all excited. I had to purchase the entire James Bond Collection on DVD from JB (on special for $80.50 – RRP $115).  I now have 24 movies (nearly 100 hours) and six iconic James Bond actors to catch up on before I can see ‘No Time to Die’ – now fortunately scheduled for April 2021.

Damn you as I should be doing reviews on your phone instead of enjoying myself. BTW the movies are a perfect way to spend summer.

Or as Moneypenny might say to James, “Is that a Walther PPK Nokia 8.3 in your pocket or are you just glad to see me?”

Nokia 8.3 5G Model TA-1234 DS 8/128 (look for ANZO region on the label)

  • Australian website here
  • Price: $899 but shop around as JB Hi-Fi has it for $719
  • Colours: Polar Night
  • From: JB Hi-Fi, Harvey Norman and Nokia Official Store on Amazon
  • Elevator pitch: 5G and Bondish intrigue
  • Warranty: 24-months Hassle-Free replacement warranty – excellent
  • Country of Manufacture: China
  • Nokia is a smartphone brand owned by HMD Global in Espoo, Finland. Many ex-Nokia executives run it. Microsoft previously destroyed the brand from 2014 to make Windows Mobile handsets. The .3 series (2020) are the fourth generation under HMD.

First impression – PASS+

Big glass slabs are still in vogue. This is 171.90 x 78.56 x 8.99 mm x 227g. It has a flat 6.81″ screen and narrow bezels curving over to meet the frame.

The real action is on the back. It is ‘Polar Night’, and you can have and Aurora Borealis right in your hand. It is blue, deep teal, and coloured bands of light move as you rotate it. But it is hugely slippery, and the TPU bumper case ruins that effect.

Did I mention hugely slippery? Several times a day it would slip, by itself, off a glass desk or polished timber side-table. It got to the stage that we put a rubber mat under it to help defy gravity (or use the TPU case).

On the back is a round ‘signature’ camera hump with four ‘so-called’ Zeiss lenses and a dual flash. More on that later.

The right side has the combo fingerprint/power and volume up/down buttons. On the left is a Google Assistant button. And it is complete with 3.5mm combo audio jack.

Right now, let me tell you it loses points big time for the incredibly poor Google Assistant Button placement. With one-handed use – every time you use the combo power/fingerprint button on the right side, you accidentally fire up Google. Arrgh!

Nokia 8.3 5G Throttle

The Qualcomm SD765G is my favourite Goldilocks chip of 2020 – just right. But this one is performing up to 20% less than the pack.

Other makers have utilised the SD765G’s comprehensive feature set like Wi-Fi 6 AX, dual-channel GPS, Aqstic audio engine, Dolby Atmos, USB-C 3.1 and QC 4 charging. Sorry, but our tests found none of these.

Now I know that Pure Android may limit some of these features, but it was rather a lacklustre performer compared to other SD765G devices.

Comms – PASS

Wi-Fi Wi-Fi 5 AC 2×2 MIMO
Signal Strength 5Ghz – distance from ASUS AX1100 router
– 2m:  –33dBm/866Mbps
– 5m: -604dBm/117Mbps
– 10m: -69/52Mbps (almost unusable but reverts to 2.4Ghz)
Bluetooth BT 5
GPS <10m accuracy for turn-by-turn navigation
NFC Yes – PayWave only
USB-C 2.0 (we were unable to read/write from external media)
Sensors Accelerometer and Gyroscope combo – this makes for a very touchy screen autorotate – turn it off.
Magnetometer
Proximity
Ambient Light

The Wi-Fi 5 speeds are average, particularly as some in this class are still able to get a strong signal at 10m.

The SSD765 supports USB-C 3.1 – this has implemented the far slower 2.0. Ditto to dual-channel GPS – this is a single channel.

The combo sensor tends to make these devices ultra-sensitive and give too many false screen rotations. Turn auto rotate off to maintain your sanity.

LTE and 5G – PASS

SIM Hybrid dual sim (one active at a time) or single sim plus micro-SD
Ring tone Dual
Support VoLTE – carrier dependent – generally yes
Wi-Fi calling – Yes
Speed Ping: 45ms

5G claimed to be the first smartphone which is compatible with all existing 5G bands.
We can’t test that, but it has n78 sub-6GHz for Australia
Test -101dBm in a 3-bar reception area (average)
Strength: 79.4fW
Found a second tower at -108dBm and 15.8W

We find that most 5G phones perform more poorly than dedicated 4G devices. It must be something to do with the antenna design as they drop too easily to 3G.

This should be a good city phone or suburban – not for regional or rural use.

Battery – PASS or maybe a fail

Battery Claimed 4500 but reported as 3300mAh
Charger 5V/3A,15w, 9V/2A/18W and 12V/1.5A/18W
Test:
30% – 30 mins
60+ – 60 mins
100% – 1.5 hrs
Tests Video Loop test: 1080p/50%/aeroplane mode – 18 hours
Typical use 4G, Wi-Fi Test – 15.5 hrs
MP3 music test: 50% volume played from storage – 40+
100% load Battery drain – 4 hrs
T-Rex –442.6min/7.38hrd/3346 frames
Idle Drain screen off: about 15 days
Idle drain screen on: 25hrs

We are concerned that the battery claim of 4500mAh shows independently on all test apps as 3300mAh. If the apps are correct, that makes a huge difference to battery life.

We found that it needed a charge every night. It is a one-day phone. Others in this class will charge as fast as 45 minutes.

It charges consistently at 5V/3A/15W in a linear manner – approx. 1.5 hours

Sound – PASSable

Why, oh why, a mono speaker at this price bracket? Class-leaders have stereo and Dolby Atmos.

Speakers Mono earpiece and down-firing speaker*
AMP Unknown – probably Qualcomm
BT codecs Codecs are SBC (standard), LDAC (Sony), aptX/HD/Adaptive (Qualcomm) and LDAC (Sony). You must enable these in Developer Options. It drove our reference Sony WH-1000xM4 in SBC, AAC and LDAC (OPUS) modes and provided good clear sound and plenty of volume.
Mic Dual NC
3.5mm Yes, and standard buds
FM Yes, with buds as aerial
Tests dB
Anything over 80dB is excellent
Media – 75
Ring – 76
Alarm – 75
Earpiece – 55
Hands-free – adequate and clear
Sound Stage It is a mono bottom-firing speaker, so there is no L/R sound stage
Signature No bass, very late-mid and lots of low-to-mid treble – it focuses on clear voice

I can’t imagine what Nokia was thinking by making its flagship smartphone a mono system. The SD765G supports so much more.

It is not as loud as others in the class and callers commented on wind noise in hands-free.


Build – PASS

Size/Weight 168 x 74 x 9 mm x 207g – it’s a big phone
Colours Polar Blue
Build Front – glass type not specified
Frame – not specified but likely metal
Back – glass type not specified
IP No
In the box Bumper cover
18W charger
USB-A to USB-C cable
3.5mm standard buds

Solid and well-made but at 227g it is a pocketful.

Nokia why didn’t you use Gorilla Glass like everyone else? Or at least tell us its toughened glass. It may be, but we don’t know.

Nokia 8.3 5G

Android 10 – PASS+

Android Google Android 10
Security patch date: 1 October 2020
UI Pure Android One
Google All standard apps, Google Lens and Assistant. Dedicated Google Assistant key.
Dedicated Google Assistant button (that is badly placed)
Bloatware Amazon, Netflix – un-installable
Update Policy Two years of guaranteed software upgrades – that means 11
Three years of monthly security updates.
Note that Google will handle security updates in Android 11
Security Fingerprint on the power key – accurate and fast
FaceID – 5/10 fails

Nokia is banking on its use of Pure Google Android will sell more phones than brands that use an User Interface over Google Android.

Yes and no.

Yes, it is nice to have a bloatware-free device and to get updates regularly.

No, a UI can add so much value and features to Pure Android. Even Motorola, a staunch Pure Android supporter, now has My UX on its 2020 devices.

Missing – FAIL

IP No IP rating. The class leader LG Velvet has IP68 and MIL-SPEC
Stereo It really should be, and Dolby Atmos would be nice
Quick Charge 18W is not really ‘quick charge’, and there are SD765G phones that can  charge in half the time
Qi Charge Not a deal-breaker but the class-leader LG Velvet has it

GadgetGuy announced this device back in March 2020. Later market entrants have better specs.

Nokia 8.3 5G Camera – PASS

It may be a quad-camera but most of the heavy lifting in by the Primary lens. And this time you don’t get Zeiss lenses – you get a Zeiss collaboration on the app – disappointing.

The primary lens is great. The ultrawide is adequate. Digital zoom and dedicated macro are poor.

The Zeiss name is not however about the hardware, lenses etc. It’s a collaboration on the app for Zeiss-tuned filter modes. I think that the use of the name Zeiss printed on the camera, in this case, verges on deceptive.

Macro

Nokia 8.3 5G macro
Very poor centre definition. We took several shots at 4cm to even get this.

Selfie

24MP binned to 6MP is fine. Screen fill flash helps

Video

You can shoot 4K@30fps with EIS stabilisation, and the results are fine, but we recommend a tripod. They are even better without EIS as the SD756G can focus on processing higher bit-rates to give saturated colours and decent details. The video sweet spot is 1080p@60fps.

The dual mics are good at stereo sound recording.

GadgetGuy’s take – Nokia 8.3 5G is a bit old fashioned like Mr Bond

I was initially excited by the Nokia 8.3 5G – it looks great. But as I stated ‘dissecting it’ I found that it was far from the class-leader in the SD765G melee.

No Qi wireless charge, IP rating, mono speaker, stupid Google button placement and a ‘PureView’ camera that should have been exceptional – except that it was average. And the issues with battery size and general lacklustre performance means it is not the class leader.

This looks and feels like a 2019 mid-range – not some of the exceptional 2020 mid-range SD765G phones we have seen.

One thing – after having reviewed so many 5G phones is that 4G signal strength seems to be low to average across them all. Its as if 5G reduces 4G signal strength.

So the kindest thing I can say is that Nokia 8.3 is a fine phone all around, but several competitors eclipse it in almost every way.

And finally, Nokia used to provide detailed specifications. Now it is a few lines, and that usually means we reviewers have to dig harder and look in more detail discovering more flaws!

Grey market – no Australian warranty

We issue the standard warning that you must buy the genuine model with Australian firmware as it works on all Australian Telco carrier 5G and 4G LTE bands and can make a 000-emergency call (not 911) without a SIM. As A 5G device, it is pre-registered to the Australian network.

We have named and shamed the major grey marketers here. If you are going to spend this much money, get a genuine ‘Made for Australia’ model.

Rating explanation – Nokia 8.3 5G

If a device PASSes every test it gets 4/5. we add points for EXCEED and take off for FAIL. This is a fine phone but it does not stand out in the crowd.

EPOS EXPAND 80 – USB/BT Conference hands-free speaker/mic par excellence

EPOS EXPAND 80 – USB/BT Conference hands-free speaker/mic par excellence
5.0Overall Score
Name: EPOS EXPAND 80 – USB/BT Conference hands-free speaker/mic
Price (RRP): $899
Manufacturer: EPOS

The EPOS EXPAND 80 – USB/BT Conference speaker/mic has exceeded all our expectations. It is scalable from a workgroup huddle to a 16-person conference room.

Whether you use unified communications (UC) or run it from a smartphone – it is an excellent addition to any small to large business that needs ultra-clear hands-free communications.

Where do you start with this? Perhaps that the EPOS EXPAND 80 USB/BT Conference speaker/mic is a product of a joint venture with Demant A/S and Sennheiser Electronic GmbH & Co. KG.

It sells to business professionals, UC users, and gamers – what a dichotomy. The EPOS AU website is here, and its pillars are performance, pioneering, crafted to last, and designed to excite. Its competitors include unified comms companies like Logitech, Jabra and Poly.

Where to start with the EPOS EXPAND 80 – USB/BT Conference speaker/mic

If in doubt start at the essential specifications

  • Six digital MEMS omnidirectional microphones for up to 16 pax. Clear voice frequency response of 150Hz-7.5kHz (for clear voice and excludes higher level noises). All mics give a 360° coverage.
  • One Neodymium ring magnet speaker for up to 85dB with low distortion (excellent)
  • It supports BT Profiles A2DP 1.3.1 + AVCTP 1.4 + AVDTP 1.3 + AVRCP 1.6 + DID 1.3 + GAVDP 1.3 + HFP 1.7 + HSP 1.2 + RFCOMM 1.2.
  • When used in BT HFP hands-free mode, it has a 50 – 7.5kHz (communication) mode 3% THD
  • When used as USB or BT A2DP, it has 50Hz-20kHz (audio streaming).
  • Maximum volume is 85dB – more than enough for a 25m2 space
  • Comes with power supply, 1.5m USB-C to USB-C cable and USB-A adapter
  • Also comes with a BT4.2 BTD 800 USB-A Dongle to enable BT on a host device
  • Two models – the EPOS EXPAND 80 for UC modes and 80T for Microsoft Teams
  • EPOS Connect app for Remote call control, firmware updates and settings. There is an overall EPOS manager app for all EPOS devices.
  • 118.6 x 46.1 x 318.8 x 980g
  • Optional expansion by up to two external mics
  • AU website here
  • Warranty 2-year ACL
  • Price: $899
EPOS EXPAND 80 and speakers
Expand to 24 or 32 people

What does it do?

If that is not obvious by now and you don’t know what UC means you don’t need to read on. There are hundreds of low-cost hands-free speaker/mics.

It is approx. $899, but you buy it from UC specialists so you may bag a bargain.

Connect it via BT (supports NFC for quick pairing) or USB, and it becomes a business-grade hands-free speaker/mic.

That is all you need to do.

EPOS EXPAND 80

From there you have buttons for volume up/down, mute, answer/reject call, swap/hold calls, BT and NFC pairing. There is also an audio playback button that appears to switch to A2DP. But a long hold summons the voice assistant of choice.

Tests

Boardroom – EXCEED

We place it in the middle of a 5 x 5m area, not dissimilar to a corporate boardroom size. Tests were on BT (using the built-in BT 5.0), and USB-C connected to a Microsoft Surface Pro 6 and a Samsung Galaxy S20 Ultra 5G.

I was seated in two test positions – 1m and 2.5m (at the edge of the room). I also walked around the room.

While mic sensitivity is subjective, the caller commented on the crystal-clear clarity of the beamforming mics. You can also add up to two more mic units to suit 24/32 people.

Maximum volume at 1m from the EPOS EXPAND 80 was 85dB and a very loud 75dB at 2.5m. Even at that level, there was no reverb or feedback – the speaker fires upwards, and the mics cover outwards.

Another test was to have three people speak at the same time. The caller said that the three conversations were quite distinct, and he understood all.

But the big test – a noisy environment – EXCEED

I took it to my local friendly café, where there are dozens of conversations ranging from whispers to shouts.

The aim was to see how effective the mic’s beamforming is. Again, this is subjective because we can only qualitatively measure results. The DSP (digital signal processor) did an amazing job of cutting ambient noise and focusing on those closest to the unit.

As a video conference hands-free – EXCEED

I suspect that I don’t need a $900 hands-free speaker/mic, but it sure makes a difference to the inbuilt mic on the Surface Pro 6.

I heard nuances in remote voices that I missed with a traditional speakerphone. But they could also hear me with no lag or reverb.

As a music device – EXCEED

It is a mono speaker and most of the time focuses on clear voice clipping at 7.5kHz.

Press the Audio button (or change to A2DP on the host device), and it opens up as an almost perfect, loud 80dB speaker.

You get strong hints of upper bass then it is flat to 10kHz where it dips to remove harshness and then back to flat almost to 20kHz. The sound signature is bright vocal  (for clear dialogue), but it has just enough bass for jazz and blues too. In other words, it was pleasant to listen to, albeit a mono speaker.

FR
You can’t ask for more!

EPOS Connect and EPOS Manager

We did not try the Windows EPOS Connect app. It can update firmware, controls calls, set up audio profiles (boardroom, office, etc.). It also supports the majority of UC protocols.

EPOS Manager is for managing a fleet of EPOS products.

EPOS EXPAND 80 Conenct

GadgetGuy’s take – EPOS EXPAND 80 – USB/BT Conference hands-free speaker/mic should be in your boardroom or huddle

EPOS may not be a name on your UC shopping list, but it should be. Lovely Sennheiser sound and quality manufacture.

EPOS has a try before you buy program for qualifying business – it is no risk.

Rating this is easy – it exceeds all tests and expectations for UC use.

Airfree air purifier it not quite what you expect – it is a steriliser

Airfree air purifier it not quite what you expect – it is a steriliser
4.0Overall Score
Name: AirFree P-series air sterilisers (air purifiers)
Price (RRP): $250-525
Manufacturer: Airfree

Airfree makes a range of air purifiers, but they are not what you would normally expect. They are air sterilisers that inactivate airborne contaminants. This includes virus, bacteria, pollen, organic odours, pet dander allergens, mould, dust mite allergens and even decomposes Ozone (O3) to Oxygen (O2).

Why is an Airfree air purifier not what you expect?

First, let me say it has been a real challenge devising test paradigm for a device that sits in a corner and apparently does nothing! Among other things, Air purifiers (reviews here) normally use Clean Air Delivery Rate (CADR), Filter Efficiency (HEPA and activated charcoal), have timers, fan settings, and are measured against noise decibels.

This does none of that – zip, nada, zilch. So, we have to rethink how to test and to learn if it works or is just an expensive toy.

How Airfree works

There are no moving parts, no fans, nothing – just a pretty LED light grill on top of a tulip-shaped small unit.

It works on the convection principle. Hot air rises out the top drawing in lower cold air from the base. As it rises, it goes through a 200°C TSS (Thermodynamic Sterilising System) ceramic core – a marketing term – not a scientific one. It is basically a hotplate.

So, for all intents and purposes, it just sits there 24x7x365 inactivating any airborne ‘bugs’ (let’s use the term generically) unlucky enough to waft into the convection airstream. And it decomposes Ozone molecules to Oxygen (at temperatures above 192.2°C).

Sceptics would LOL at this point – I did!

How can a passive device sterilise the air? I mean don’t you at least need a fan to draw in air?

Airfree is a Portuguese company. Portugal is renowned for great presunto (cured prosciutto), Port, Portuguese custard tarts, canned sardines and it grows over 50% of the world’s cork. But science – hmmm?

The Airfree concept has been in use since 2004. It is for consumer and commercial use, particularly hospitals where this silent steriliser can inactivate 99.99% of airborne bugs.

Airfree points to numerous scientific tests and I have pored over these. Let me tell you what I found.

  • In tests in a pig maternity room, it reduced odours from 154 points to 102! Not only that, but it reduced piglet mortality from 12.71% to 6.96%. Why? The reduction of airborne contaminents. The one thing it could not stop was death by crushing!
  • Another test measured Ozone input at the base and Ozone output at the top. The reduction was from 19.5 ppb to 14.4 ppb = 26%.
  • Yet another test measures the convection fan-free airflow. Over a nine-day laboratory test, the average airflow was 14 m3/hour – A standard small bedroom is about 25m3.
  • Finally, virus. An 11m3 sealed test chamber filled with  
    • Serratia Marsescens (an opportunistic harmful human pathogen) – a 63.2% reduction at 165 minutes
    • Aspergillus Niger (black mould) – no effect (because it grows on fruits, walls etc). It will destroy airborne mould spores to reduce the spread and regrowth)
    • Penicillium citrinum (Health Symptoms: Headaches, itchy and watery eyes, runny nose, congestion, coughing, sneezing and rashes) – 78.8% reduction at 195 minutes
    • MS2 (a virus) – 54.4% reduction at 150 minutes.

Well if it works for pigs, it should work for people. I am convinced.

Airfree Models – lots of choices – PASS

We tested an Airfree P150 rated for a 60m2 room (about 8x 8 x 2.4m ceiling or 144m3). All Airfree P models are all externally the same size (21.5 (diameter) x 26.5cm (height) x 1.6kg), and the capacity relates to the size of the TSS chamber.

There are other designs called Iris (coloured top LED), Lotus, Tulip, T40 and Babyair.

And note that Airfree will be selling the Duo – it has a fan and an activated charcoal filter.

Prices – well Airfree Australia (the website is loosely translated from Portuguese so forgive them) is just setting up distribution here so at present you will find them on eBay or at Wilcomp.

Other products will be available online at Catch of the Day in late November including the new Duo (it has a fan!), Baby Air 80, and T40.

Power use – PASS

The models consume from 41-58W. In dollar terms, let’s say power costs an average 30 cents per kilowatt-hour (1000 watts for an hour). Even the largest model costs less than 2 cents an hour, 48 cents a day, $175 per year etc.

We tested this via our EmberiQ meter and it was drawing 57W.

While Airfree claims that it has low energy consumption we think it is fairly high for a passive device. It is equivalent to leaving a 60W light bulb on 24/7 (or 12 LED downlights).

External temperature – PASS

The hot air cools slightly as rises from the top. AirFree states it is equivalent to the heat that a 70kg person produces.

We measured 76° at the top outlet. Now that is not burning (boiling water is 100°) and won’t hurt anyone if they put their hand on it but it is quite warm.

Placement and Safety – PASS with a caveat

Airfree

Its relatively small and light. If placed on a floor (as recommended – no higher than 75cm off the floor) children or pets could knock it over. There is a safety cut-out, and the LED light will flash.

The power cable is approx. 1.4m. Airfree says to place in an area with air circulation. The manual says avoid placement near open doors, curtains or windows to prevent sterilised air exiting the room.

Nightlight – PASS but it is blue light

Blue light can interfere with circadian rhythms for sleep. You can turn the light off.

Maintenance – PASS

There is nothing to replace. As far as I can find, there is no set lifespan of the TSS chamber. Expect at least five years, if not many more.

As it does not have a fan, there should be little build-up of dust on the air intake/outflow areas.

Warranty – PASS

The warranty is 2-years if purchased from an approved Australian reseller ACL applies. Australian Consumer Law states the supplier must pay freight both ways if it is not easy for you to return it!

The body is made from polycarbonate which can undergo large deformations without cracking or breaking. it complies with California’s Proposition 65.

What it is not – PASS

  • It is not a dehumidifier nor a humidifier. It has no effect on mould growing on walls or in cupboards. Any airborne spores that end up in the TSS chamber are killed.
  • It is not an air purifier that removes particulate matter or volatile gases via a filtering system. If you see any review that claims dust reduction, it is a fake review!

So, what did we learn about Airfree? Does it work – PASS

  • Depending on the model (bigger is better) it should sterilise the air at about 14m3 per hour if left on 24x7x365
  • Kills any airborne contaminant if it gets to the TSS chamber
  • It is a silent killer
  • Does not use any disposable filters
  • Has no moving part and should last a lifetime (well, five years)

GadgetGuy’s take – Airfree air purifier is a silent ‘bug’ killer

I have read everything I can, all reviews and tests. Most are positive, and all mention that you have to have faith that it works. The negative ones say that they have not noticed a reduction in sneezing, coughing etc.

And that is the conundrum. You cannot rate it as an air purifier. But from two weeks of testing all I can say is that I think it works. I have no proof; I cannot measure ‘bug’ reduction.

We have now been testing for a month in a 25m2 bedroom. Has there been noticeable effects? Well as a chronic hay-fever sufferer I think so. Where I would normally sniff and snort all night long I appear to have a clear nose. So we will pay that one.

Would I buy it?

If it works as it seems then yes, especially as I suffer from hay fever and allergy. However, I think its a tad over-priced.

Most will still need larger room-sized filter-based air purifiers to remove smoke, particulate matter and SO2 (volatile gasses). If anything, these do make a visible difference to dust reduction.

I suspect it is most useful in semi-closed systems like bedrooms where it can reduce airborne contaminent.

Rating

It is not an air purifier. There are no established benchmarks for air sterilisers, so we will start as PASS 4/5.

BTW Productreview.com.au has a five-star rating from six users who all comment on the effectiveness for allergies and coughs – let’s hope.

The video below is for an older model – looks similar and explains what it does.

Belkin AUF001 – BOOST↑CHARGE 10W Wireless Charging Stand and Speaker

Belkin AUF001 - BOOST↑CHARGE 10W Wireless Charging Stand and Speaker
4.0Overall Score
Name: Belkin AUF001 - BOOST↑CHARGE 10W Wireless Charging Stand and Speaker
Price (RRP): $99.95
Manufacturer: Belkin

The Belkin AUF001 – BOOST↑CHARGE 10W Wireless Charging Stand and Speaker – is a natty all-in-one Qi 10W wireless charger, mini-BT speaker and mic for hands-free speakerphone use.

It is the kind of gift that you might find under a techies Xmas tree. At $99.95, it is affordable enough to cross over from that ‘cheapskate’ to ‘I really love you’ gift.

There is not a lot to review here. We can check charging wattage; we could (and did) check speaker frequency response (mono – that is it) and such other. But really what you need to know is that it works as advertised and it is from a quality company.

Belkin AUF001 – BOOST↑CHARGE 10W Wireless Charging Stand and Speaker –

  • Website here
  • Price: $99.95
  • Colours: Black or White
  • Size: 11- x 1-2 x 1-6mm x 110g
  • Warranty: 2-years and $2500 connected equipment insurance
  • From: Good CE retailers
  • Made in Vietnam
  • Belkin is owned now by Foxconn

NOTE: It is not for iPhone 12 MagSafe devices or other magnetic devices such as an Apple Watch.

Qi Tests – PASS

Modern Qi-certified chargers’ output 5V/1A/5W, 5V/1.5A/7.5W and 5V/2A/10W (approx.) to cover earbuds (5W), iPhone to 11 (7.5W) and most other Android Qi smartphones (10W).

It comes with a 12V/1.5A/18W plug wall charger.

Even though Belkin calls it a fast charger – it is not really. Fast charge usually starts with high voltage/amps for the first 60-80% then scales back.

In tests, it locked onto a specific voltage/amperage and stayed there until full.

For example, with an iPhone 8, it locked at 5V/1.5A. With Samsung Galaxy, it was 5V/2A.

We also tested efficiency – the ability to convert Qi power to battery charge. Belkin does not quote figures, but it is creditable for a single coil charger at approx. 70% (Qi maxes out at about 85%). What that means is that it will take about 30% longer to charge the iPhone.

It has the usual Qi charging safeguards.

Usability – PASS

It has a vertical stand design which means that it does not suit anything other than smartphones – no AirPod charging here (although you could). The design allows for portrait or landscape. The latter is important for smaller smartphones where you need to align both charging coils or efficiency drops off.

It can handle TPU cases to 3mm. Qi cannot charge through metal, alloy or thicker cases; hence the warning on Apple iPhone 12-series.

Belkin AUF001

BT speaker – PASSable

It is a standard BT 5.0 single-point pairing with any BT host device – phone, Window, Mac etc.

But don’t expect ‘quality’ music as the default is a hands-free phone (HFP) that cuts the frequency response and transmits in mono to allow the other channel for a mic.

Maximum volume at the speaker is 80dB and at 1metre is 76dB.

How does it sound? PASSable

Belkin claims a frequency response of 250Hz to 20kHz. In essence, that means no bass or lower mid – they are right.

You must remember it is an upwards-slightly backwards-firing, 3W, 4Ω, 40mm speaker. Its main purpose is to provide clear dialogue for voice calls – not so much music. Below is the HFP hands-free mode.

Belkin AUF001 HFP

You can disable ‘calls’ which implements the A2DP protocol that improves the frequency response. Below is the audio-only mode.

Belkin AUF001 A2DP

In any case, it is an analytical signature.

Mic – PASSable

As it is for indoor, up-close-and-personal use, its sensitivity is quite low. The mic is in front of the speaker, and feedback can occur at higher volumes. Its fine for hands-free use but callers commented that I sounded like I was in a tunnel as the phone was in front of it.

Belkin Connected equipment warranty – EXCEED

It covers damage up to $2500 if the device should damage the phone.

GadgetGuy’s take – Belkin AUF001 – BOOST↑CHARGE Wireless Charging Stand + Speaker is what it is

It is a good 10W Qi charger with an adequate BT hands-free speakerphone at a reasonable $99.95 price. You can get the same 10W charger without a speaker for $59.95. Given that I require a higher stereo audio standard (mono is so yesterday) that is what I would buy.

Rating explanation

A hard one to rate. As a Qi charger, it scores a PASS for everything, so it starts at 4/5.

As a hands-free speaker phone its PASSable.

But as a quality Belkin product with the 2-year warranty and connected equipment warranty it EXCEEDS.

Given that a lot of people are using Google Duo for video calls its a perfect device for that.

Apple iPhone 12 DXOMARK camera ratings

The Apple iPhone 12 DXOMARK camera ratings for the iPhone 12, Pro and Pro Max score a very respectable 120, 130 and 132 for the rear camera. Congrats Apple.

DXOMARK is not the definitive test, but it is consistent between camera brands and models. As such, it provides a ranking based on a weighted average of scores across Still, Zoom and Video.

And before you read the reviews let me say that until recently DXOMARK had ranking out of 100. It had to invent new scales (V3) to accommodate multi-sensor/lens/AI as well as periscope zoom and night vision. As we used to say then – any score above 90 is damned good. Well, now its any score above 110 (our reference is the Pixel 4a) is damned good.

Anyway, DXOMARK now has to invent a new test protocol V4 for future tests. Recent smartphones are pushing the limits of V3, especially in the areas of Dolby Vision HDR, DCI-P3 (movie gamut) and storage formats. Smartphone camera tech is leaping ahead as a major point of difference because anyone can make a decent phone!

It is interesting in the Google Android world that the Xiaomi Mi 10 Ultra scores an average of 133, Xiaomi Mi 10 Pro 128, Samsung Galaxy S20 Ultra 5G 126 and my favourite zoom cameras the vivo X50 Pro  137 and OPPO Find X2 Pro 126.

BTW we can’t include Huawei as it does not have Google Android so necessary here.

Apple iPhone 12 DXOMARK camera ratings for 12, Pro and Pro Max – read the reports

DXOMARK – Apple iPhone 12 122

Has 2 x 12MP sensors – standard-wide, ultra-wide.

It is strong on still images (Weighted Av 132) with its strongest points being Autofocus (106), Colour (98) and Texture (98).

It was let down on Zoom (41) – it is digital, not optical.

The AI also lets it down badly with Noise, Artifacts, Night, Bokeh (no LiDAR or depth sensors) and Preview (what you see is not what you get) scoring between 55-74. These are AI computational photography issues, and Apple may well address them in future firmware updates.

Apple iPhone 12 DXOMARK

DXOMARK – Apple iPhone 12 Pro 128

Has 3 x 12MP sensors – standard-wide, ultra-wide, and telephoto modules, differentiating it from the iPhone 12 and iPhone 12 Mini sans tele and LiDAR.

It is strong on still images (Weighted Av 135) with>100 colour accuracy, autofocus and texture. But it was let down by average to poor scores (66-77) in Noise, Artifacts, Night mode, Bokeh and Preview.

It lost points with the 2X Optical zoom and wide-angle lens averaging 66.

Video was 112 with all bar artifacts and texture scoring >100 – ditto to AI issues. Good reflecting Apples DCI-P3 colour gamut adoption.

Apple iPhone 12 DXOMARK

DXOMARK – Apple iPhone 12 Pro MAX 130

Essentially the same as the Pro with bigger main lens sensor pixels and a slightly larger telephoto field of view.

It is very strong on still images (Weighted Av 138) with>100 colour accuracy, autofocus and texture; otherwise it scored similarly to the iPhone 12 Pro.

The bigger FOV telephoto gained it two more points to 68.

Video was 113 due to the slightly larger main sensor pixels. Otherwise it scored similarly to the iPhone 12 Pro.

Apple iPhone 12 DXOMARK

GadgetGuy’s take – Apple iPhone 12 DXOMARK camera ratings – good job Apple

These are credible overall ratings that show Apple can make a smartphone camera that is up there with the best Google Android phones (or vice versa😉)

It concerns me that it’s AI algorithms are not quite right, but that is fixable. Hell, knowing Apple it is a feature, not a big, to charge more for!

But we repeat, don’t get hung up over what brand and model has the best camera – anything above 114 is indistinguishable to your eyes from whatever holds the current crown.

And as these scores generally reflect financially unobtainable models (for most of us). Take heart that there are some great lower-cost phones in the upper camera performance bracket (DXOMARK in brackets)

Sennheiser MKE 200 directional microphone

Sennheiser MKE 200 directional microphone
4.8Overall Score
Name: Sennheiser MKE 200 directional microphone
Price (RRP): $199
Manufacturer: Sennheiser

Almost exactly a year after reviewing Sennheiser’s entry level microphone for cameras, we now have the Sennheiser MKE 200, an even entrier-level, if I may, microphone for cameras. And for smart phones and computers.

Review: Sennheiser MKE 200 directional microphone

  • Manual and support here here.
  • Price: A$199 – seen for as low as $161 on the web.
  • From: Legitimate retailers and direct.
  • Warranty: 12 months

About the Sennheiser MKE 200 directional microphone

Of course, if your modern mirrorless (and even DSLR) camera can take video, it has a microphone built in. But that microphone resides behind a pinhole in the camera’s metal case. That they produce adequate sound much of the time is almost miraculous. But a simple, $199 upgrade is always welcome. And that’s what the Sennheiser MKE 200 directional microphone aims to provide.

The bulk of the Sennheiser MKE 200 – although perhaps “bulk” is a misleading term – is a perforated cylinder some 35mm in diameter and 69mm long. This is attached to a holder, on the other end of which is cold shoe mount designed to slip into the flash shoe of a camera. It has a ring clamp to make sure it’s safely attached. Underneath the mount is a quarter-inch threaded hole for use with a camera tripod. It’s good to have options. From the bottom of the mount to the top of the microphone cylinder is slightly under 60mm. And the whole thing weighs 46.6 grams. You’ll barely notice it on your camera.

Inside the cylinder is a small pre-polarised condenser microphone capsule, held in a shock mount. This has a super cardioid pickup pattern. Sennheiser rates the frequency response at 40 to 20,000 hertz. I’ve copied in Sennheiser’s graph below.

Looking at that response graph, it seems that Sennheiser had engineered with a fairly recessed bass end. Compared to 1kHz, the level is down by a dozen decibels at 100 hertz and 20dB at 50 hertz. Don’t expect deep bass.

Sennheiser MKE 200 bits and pieces

The microphone can cope with sound pressure levels of up to 120dB. Unlike that earlier microphone, this one uses no batteries. It draws a tiny amount of power from the camera or phone. (The draw is minimal: the voltage is required to charge up the plates in a condenser microphone, but the actual current draw is miniscule.) Anywhere between two and ten volts is fine.

In the box you get the microphone, a furry wind shield which you can stretch over the microphone, a soft carry pouch and two coiled cables. One is terminated in a regular 3.5mm plug in TRS – Tip, Ring, Sleeve – configuration. This should work with all cameras. The other is terminated in a 3.5mm TRRS plug, which is suitable for smart phones with a physical connection, tablets and computers.

Sennheiser MKE 200

Both cables are terminated at the microphone end with a standard 3.5mm TRS plug, but with a locking collar for security. The blue colouring of the cable is, I think, a nice touch. The microphone is black, but the cable somewhat draws attention to the fact that you’re going a bit above and beyond in terms of sound.

You attach the microphone to the camera with the longer part of the cylinder, and the cable connection, facing towards the front.

I did my testing using the Fujifilm X-T4 camera which we recently reviewed here. The camera permits manual adjustment of the volume level, but I just left it in auto level mode. I could not find a setting in the camera to switch power on or off to the microphone jack. Given that it worked, I assume that it has power on all the time. I could not find in the camera’s manual mention of the actual voltage level.

In use

Sometimes I find these microphones hard to jam into the camera shoe. That’s usually because the plate is fairly thick. This one slid in very easily – thankfully – but do tighten the collar clamp or it may well just slip out again.

Because the microphone is so compact, I found it very convenient, and left it in the shoe whenever there was a chance I might be taking some video.

Testing sound quality is always a little tricky. I made three A-B tests. That is, I repeated the three scenarios twice, the first with the Sennheiser MKE 200 in place, the second relying on the camera’s built-in microphones.

In summary, the Sennheiser was enormously better at rejecting sounds from behind the camera, and noticeably better at softening sounds to the side. It also seemed more focused, more precise than the built-in microphones.

You need not merely take my word for it. See for yourself how it went.

The walk-around test

First, here’s me walking around the camera with the Sennheiser MKE 200 in use:

And then me, exactly the same but using the built-in microphones on the Fujifilm X-T4 camera. This has two pinhole microphones to the left and right of the swelling around the viewfinder.

The most obvious difference is that the Sennheiser is highly directional. I’m prattling on about something or other while directly to the rear of the microphone, and it’s very hard to make out what I’m saying. Using the camera’s own microphones, the sound is much the same level regardless of direction.

This can have its advantages, but if you’re interviewing someone outdoors, wide sound capture is the last thing you want. With the Sennheiser MKE 200 there’s still a moderate amount of sound out to perhaps 45 degrees. So if you’re doing roadside interviews, try to have your subject such that the angle to the traffic is more than 45 degrees to keep traffic noise to a minimum. Go beyond 90 degreess for real noise isolation. With the camera’s microphones, your subject will probably be drowned out by passing vehicles, regardless of the direction in which the camera is facing.

Initially I thought my voice was significantly louder with the camera microphones, but after running through them a couple of times, I’m now thinking the voice is much the same level in both, while it’s the background noise which is louder in the camera-only microphones video.

Pay attention to the difference in distance traffic noise. The Sennheiser is much quieter in the background noise.

The sounds of nature

Here’s one of the rivers near Canberra, nicely full and flowing thanks to recent rainfalls. 20 seconds of the Sennheiser MKE 200 capturing the sound:

And here is the same scene, a minute later, using the camera’s own microphones:

This time the Sennheiser microphone is markedly louder. Why? In both cases the camera is on auto level, so why it chose a higher level with the Sennheiser rather than the in-camera microphone is a mystery. Trying to tune out the level difference, I’d say that the Sennheiser has more bite, grabbing more high frequencies for a slightly more realistic sound.

How about some music

I should have gone looking for some buskers. But, you know, deadlines and such. So instead I played some music through a pair of speakers and recorded it with the Sennheiser MKE 200, and again with just the camera microphones. The music is a nine-second snippet from Laura Marling’s Once I Was an Eagle. Great record. Buy it. The speakers? A pair of Yamaha NS3000 bookshelf-sized speakers. RRP is $12,999. And, no, I did not put the comma in the wrong place.

Here it is with the Sennheiser microphone:

And relying on the camera microphones:

Again, the camera decided to set the Sennheiser microphone to a higher level than the inbuilt ones. Adjusting the playback levels as best I could, clearly there were differences. Not much level difference this time. But I’m not sure which I actually preferred. The Sennheiser had a bit more upper midrange, the camera microphones a slightly smoother overall feel, along with a more accurate bass level. Perhaps it’s the bass that the camera uses for level setting. Anyway, judge for yourself.

Gadgetguy’s Take – The Sennheiser MKE 200 is a worthy addition to a modern video-capable camera

I just realised that in the last few sections I’ve been comparing a $199 microphone to the microphones built into a $2,999 (for the body only!) camera. The built-in microphones are really pretty good. What the Sennheiser MKE 200 microphone offers is control and directionality. And I reckon if you couple it with any budget camera (so long as it has a flash shoe), you’d get significant improvements in the sound of your recordings.
