Denon AH-C830NCW Review
Denon decides the time is finally right…
In This Article
Verdict
Taken on their own terms, the Denon AH-C830NCW are a very likeable pair of true wireless in-ears indeed. How many people will take them on their own terms, though?

Key Features
Introduction
When you realise companies with no audio background whatsoever want to sell you true wireless in-ear headphones, it seems a bit weird that a brand such as Denon – with well over a century of experience under its belt – is only just getting in on the action.
After all, the market seems to be packed to capacity. How can a brand (even a brand with the reputation and credibility of Denon) hope to stand out?
Availability
The Denon AH-C830NCW are on sale now. In the UK, they’re priced at £139 or thereabouts, while customers in the US will need to hand over $159. In Australia, the asking price is around the AU$259 mark.
You don’t need to be a keen observer of the electronics industry to realise you can spend this sort of money on a pair of true wireless in-ears from any number of brands. Apple, Beats,Cambridge Audio, Sennheiser,Sony… I could go on, but what would be the point? Basically, you’re spoiled for choice and Denon is just another name on the list.
Design
It isn’t easy when a product is as little as this, but Denon has managed to make the AH-C830NCW look and feel quite expensive. The flawlessly shiny finish doesn’t do any harm, and the angled silver cap at the end of each stem makes the earbuds look like a more premium proposition than, say, theApple AirPods equivalent.
A choice of three sizes of silicone eartip, combined with a per-bud weight of 5.3g, means the AH-C830NCW are easy to fit and stay comfortable once you’ve done so. And when they’re not in use, the charging case is just as tidily finished as the earbuds themselves. It only charges via USB-C, though – there’s no wireless charging available here. And that shiny finish is slippy, too – which makes getting the earbuds back out of their case a little more fiddly than it otherwise would be.
Features
As far as the business of serving up music goes, the Denon AH-C830NCW useBluetooth 5.0for wireless connectivity. They’re compatible with SBC and AAC codecs – and that’s your lot. At this sort of money, any number of rival designs can accommodate aptX as a minimum, and it’s a pity to see Denon ignoring the opportunity. Once it’s on board, audio information is served up by a couple of 11 x 10mm full-range dynamic drivers.
Active noise cancellation is governed by a couple of mics in each earbud, while call quality is handled by three more. With ANC switched on, you’re looking at just shy of five hours of battery power from the earbuds themselves; switch ANC off and you can expect closer to six hours. The case itself will hold another four full charges, so you should hope to achieve somewhere between 25 and 30 hours of playback before a visit to the mains is required.
As far as control is concerned, the Denon fall quite heavily into the just about “adequate, I suppose” category. A responsive touch-surface on each earbud covers play/pause, skip forwards/backwards, answer/end call and noise-cancellation (the latter has ‘on’, ‘off’ or ‘ambient sound’ as its options). And as far as bossing your earbuds around, that’s your lot.
There’s no voice control. There’s no control app. Which means there’s no facility to adjust EQ levels or anything like that. In fact, you can’t even adjust volume levels without using your music player to do so. As Points of Difference go, this isn’t one with which Denon should be especially pleased.
Sound Quality
With no EQ adjustment available at any point, Denon has made a rod for its own back with the AH-C830NCW. Unless the company has voiced these earbuds to sound good to pretty much everyone, with pretty much any genre of music, there may be trouble ahead…
…but to be honest, it’s difficult to see how Denon could have done a better job where the sound design of these earbuds is concerned. Will the sound appeal to everyone? Probably not – there are plenty of listeners who confuse ‘too much bass’ with ‘excitement’. Will the AH-C830NCW deal faultlessly with every genre of music? Probably not – there are some categories that thrive almost exclusively on ‘too much bass’. But for the rest of us, the Denon are a poised, balanced, realistically musical and periodically thrilling listen.
A relatively complex and musicianly recording such as Sunglasses by Black Country, New Road makes the point in some style. The balance the Denon strike is nigh-on ideal – from the deep, textured and properly controlled low frequencies to the bright, shining and equally detailed top-end, tonality is consistent and believable. In between, the AT-C830NCW pile on the details to the point that a singer sounds like a characterful individual with specific intentions.
Rhythms are expressed organically – even rhythms as gimpy as those on display during this recording. The dynamics of the tune – the broad pile-ons and the finer harmonic variations – are given proper articulation, too. The Denon manage to create a wide, deep soundstage and position individual instruments on it with absolute certainty, and do so without making any element of the recording sound remote or estranged. There’s convincing unity to the way the Denon present the song, a harmoniousness that’s by no means a given in wireless earbuds at any price.
The active noise-cancellation circuitry is a slightly more qualified success. Taken in isolation, the Denon do a decent job of minimising external distractions without introducing a sensation of counter-signal or particularly affecting the way they deliver music. But compared to the best alternatives, the AH-C830NCW are just slightly tentative – other designs will isolate you more effectively from the sound of the outside world.

Final Thoughts
Why it’s taken Denon this long to launch some true wireless in-ear headphones is anyone’s guess – and it’s equally difficult to know why there are such significant gaps in their functionality. But in terms of sound, there’s an awful lot to admire here.
