Audio Pro Addon C10 MkII: Two -minute review
The Audio Pro Addon C10 MkII is a predictably good-looking wireless speaker with plenty going for it purely in design terms (as long as you’re OK with monochrome). It’s lost its handle and its Amazon Alexa voice control compared with the original model, but it’s gained a swanky new streaming platform (thanks, WiiM!) which offers an absolute stack of options where music sources and system flexibility are concerned.
Best of all, it’s a fine-sounding speaker that is able to extract an absolute stack of information from a recording and put it into convincing context. It’s punchy when it needs to be, it’s insightful, and it sounds a heck of a lot bigger than it looks. Deft control of the low frequencies, plenty of midrange articulacy and a winning way with dynamic variations all add to its sonic charm. If it was just a little more vibrant and exciting when the music demanded it, the Audio Pro Addon C10 MkII would be absolutely ideal, but it is nevertheless worthy of a place among the best wireless speakers out there.
Audio Pro Addon C10 MkII review: Price and release date
- Cost $360 / £259 / AU$530 (approx.)
- Launched in 2021
When the Audio Pro Addon C10 MkII first launched back in 2021, it cost $450 / £329 / AU$674 (approx.).
Fast-forward to today, and not only has this product become even more compelling thanks to upgrades in its streaming support and smart features, but it’s also routinely available for $360 / £259 / AU$530 (approx.). It looks like rather than becoming outdated, the C10 MkII has matured and evolved…
Audio Pro Addon C10 MkII review: Features
- 80 watts of power
- Dual-band Wi-Fi and Bluetooth 4.2
- Numerous streaming options
It’s fair to say that Bluetooth 4.2 with SBC and AAC codec compatibility is not the most inspiring specification for a wireless speaker in 2025. But what the Audio Pro Addon C10 MkII lacks in cutting-edge Bluetooth chops, it more than makes up for in its wireless network abilities.
The exemplary control app, which is now bolted to WiiM’s extremely well-regarded streaming platform, allows you to integrate a lot of music streaming services – and I mean a lot: Amazon and Apple Music, Deezer and Spotify, Qobuz and Tidal, QQ Music, iHeart Radio and vTuner, and plenty more besides. The C10 MkII is compatible with Apple AirPlay 2 and Google Chromecast, and the app allows the speaker to be half of a stereo pair or part of a multi-room system without any fuss whatsoever. It’s an extremely flexible device.
Once aboard, digital audio information is processed by a 24bit/96kHz DAC and then is breathed on by 80 watts of Class D amplification. A pair of 19mm tweeters get 20 watts of power each, and in between them there’s a 133mm midrange driver that receives the other 40 watts. This bigger driver is supported by a rear-facing vertical bass reflex port.
Audio Pro Addon C10 MkII review: Sound quality
- Open, detailed and well-controlled sound
- Great tonal balance and frequency response
- Could sound a little more exciting
Yes, by the standards for $350-ish wireless speakers the Audio Pro Addon C10 MkII is quite large. But be assured the sound it creates is plenty larger than the cabinet it’s coming from.
The sort of scale the Audio Pro can invest in a FLAC file of Hookworms’ Negative Space is straightforwardly impressive. It can open the recording out and offer a proper sense of space at the same time, even though the point-source of sound is always obvious. The amount of dynamic headroom that’s available allows the speaker to track the ever-increasing intensity of the recording convincingly, and the control of the lowest frequencies is such that rhythmic expression is confident and naturalistic, too.
And as well as being controlled with real authority, the bottom end – like the rest of the frequency range – is loaded with detail and variation. The C10 MkII is no thumper – it hits good and hard at the low end, but is textured and tonally varied. The same is true at the opposite end, where treble sounds are bright and substantial, with plenty of information available regarding tone, attack and decay. Through the midrange, the Audio Pro is about as explicit and as eloquent as any device of its type and price I’ve heard. It communicates in absolute torrents.
The tonal balance is nicely judged – it’s not absolutely neutral, but the tiny suggestion of warmth (especially towards the bottom end) is almost certainly sensible in the context of the circumstances the C10 MkII will probably be used in. The evenness of the frequency response is splendid, too, giving measured and appropriate weighting to every part of the tonal range, without underplaying or overstating any particular area.
Really, about the only area of mild concern where the sound of this speaker is concerned has little to do with the specifics of performance – it’s more about attitude. For all of its undoubted dynamic potency and ability to paint a full and nicely detailed picture, the Audio Pro is not the most demonstrative listen.
It sounds quite like it looks: sophisticated, understated and in unarguable good taste. This, where audio quality is concerned, can be considered shorthand for ‘slight lack of excitement’. No one is interested in a feral loudspeaker, of course, but at those moments when a recording demands vigor and attack, I get the strong impression the C10 MkII thinks this kind of behavior is a little beneath it.
- Sound quality score: 4.5 / 5
Audio Pro Addon C10 MkII review: Design
- 165 x 320 x 185mm (HxWxD)
- Black, white or gray matte finishes
- Magnetically attached grille
The Audio Pro Addon C10 MkII is, by the standards of a ‘rectangular box’ wireless speaker, very nicely finished and actually quite elegant in an understated sort of way.
This is just as well – given the 165 x 320 x 185mm (HxWxD) dimensions, it could have very easily ended up looking a bit bulky. As it is, though, the standard of construction and finish, along with the unapologetically monotone options of black, gray or white matte colours, make for a very harmonious look. The magnetically attached grille helps with the clean look, too.
It’s a fairly sizeable proposition on the average desk, though, and the lack of a handle makes transporting its 4.3kg weight rather less easy than it might be. I can’t deny I’ve used the bass reflex port as a handle, but I can’t imagine Audio Pro would recommend it as an option…
Audio Pro Addon C10 MkII review: Usability and setup
- Great control app, extensive physical controls
- No voice control
- Can easily be part of a multi-room set-up
Unlike the previous generation of C10, there’s no Amazon Alexa voice control here – there’s no voice control at all, in fact. You may count this as a negative, you may not, but there’s no denying that your other control options are very nicely realized indeed.
That WiiM-powered control app, as already mentioned, is stable, logical and slick in operation. As well as the ability to integrate a generous number of music streaming services and internet radio providers, it’s also where you can form a stereo pair or establish a multi-room system. There’s bass and treble adjustment, the ability to establish as many as half a dozen presets, input selection, the ability to check for firmware updates and various timer and alarm-clock functions.
The top surface of the cabinet features a selection of controls, too, embedded in a tactile steel plate. Power, volume, playback control and Bluetooth pairing are all available here, and access to the six presets you’ve defined in the control app are also available. There’s also a little LED giving confirmation of the selected input.
- Usability and setup score: 4.5 / 5
Audio Pro Addon C10 MkII review: Value
- Excellent standard of finish
- Versatile streaming platform and app
- Extras add up to value for money
Consider the standard of build and finish, and then consider the out-and-out sound quality. Take into account the great new WiiM-powered streaming platform and all its possibilities, from forming a true stereo pair to easily creating a multi-room system.
And then look around at what this kind of money can buy you from alternative brands. Yes, the Audio Pro Addon C10 MkII is very good value for money indeed.

Audio Pro Addon C10 MkII: Also consider
How I tested the Audio Pro Addon C10 MkII
Because the C10 MkII is mains-powered rather than battery-powered, I listened to it exclusively in my home. It’s a bit big for a desktop speaker, but nevertheless I gave it a go – it was much more at home on a shelf in the lounge, though.
I listened to music from Tidal and Qobuz via the excellent control app, of many types and quite a few different file sizes. And I listened both critically and with the Audio Pro functioning simply as a ‘background’ device – and there were never less than thoroughly enjoyable.
