Bluetooth 5.0 is average. The buds will connect instantly to recognized devices once taken out of the charging vase. Google Fast Pair expedites the process on Android smartphones. Range can extend up to 40 feet before dropout occurs.

Denon equipped the AH-C830NCW with 0.4-inch oval dynamic drivers that dish out solid lows, mids, and highs across the board. Bass response won’t rattle your skull, but it is rich and well controlled. Stavinsky’s The Rite of Spring as played by the Royal Liverpool Philarmonic orchestra shows a calmer, more delicate side to the little buds. Denon has even managed to bring a tiny touch of individuality to the ‘stem’ design, too - it finishes at an angle and is capped in contrasting silver. No app also means you will have to make do with the default setup for touch controls. This isn’t the end of the world as the controls cover most bases but some level of customisation would certainly be welcome.Denon didn't hit it out of the park with the AH-C830NCW, but it certainly didn't come out with a dud, either. These are solid earbuds that do a key fundamental well, which is sound quality. The fit is hard to measure because of how subjective it may be, but if you can get that right, you will like the combination. It's just a shame there is no real customization involved from an app perspective. If you’re hoping for more in an app, you’ll be disappointed: There is none. Noise-canceling in practice

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 This is a strange, rather user-unfriendly omission, given how much it constrains the ability to edit the controls, the EQ, and the noise cancellation levels. I’ve reached out about whether they are going to release one and once they reply, I’ll update this review. Soundcore Liberty 3 Pro: Better battery life, wireless charging, customizations, and hi-res audio on Android devices, but ANC isn’t as good. Having said that, though, the most committed bass-heads will probably want to look elsewhere. The low frequencies these earbuds deliver are deep, sure, nicely shaped and textured… but they’re balanced, too, where many alternatives push them forwards in the name of ‘excitement’. Listen to David Holmes’ Gone and even the deepest bass sounds stay in their lane, keeping clear of the midrange and allowing the rhythm and tempo full expression rather than dragging at it. That’s as it should be, but not every true wireless earbud is brave enough to insist on it.

Mid-bass is nice and fat, while the mids are perfectly balanced. You couldn’t want for more, in all honesty, and I think that’s high praise indeed. Denon claims up to 4.8 hours per charge and 19 hours in total when you include the charging case and you’ve got ANC turned on. When ANC is off, this goes up to six and 24 hours respectively. That’s about the same as the AirPods Pro, which is to say, not bad — enough for a full day — but nothing impressive by today’s standards. I couldn’t fully test these claims because the wear sensors can’t be defeated, but based on the remaining battery life visible in my Google Pixel 5’s control center, it looks pretty accurate. You get an audible low-battery warning from the earbuds, but there’s no fast-charge option for topping up a nearly dead battery. Our take For clear voice calls, Denon's AH-C830NCW Noise Cancelling Earbuds feature dual beamforming microphones working in conjunction, with a third mic taking advantage of the ear canal’s natural shielding against wind and ambient noise to bring additional voice clarity. The Denon AH-C630W Wireless Earbuds (above), meanwhile, use a single microphone for voice calls.

No EQ adjustment means dealing with the sound Denon has dealt, which may not seem ideal to any number of prospective owners. Those who hear the AT-C830NCW in action, though, will realise it’s not the deal-breaker it might have been. Denon has voiced these earbuds expertly. I was content with their active noise cancelling capabilities, too. With ANC enabled, the whoosh of passing traffic when walking beside a busy road was reduced to a quieter grumble and the ANC system did a solid job attenuating low and mid-range noise. Higher-pitched squeals made by a police siren, my washing machine and the clinking of kitchen utensils weren’t attenuated as well but that’s not unusual for earbuds at this price point. I’ve got no complaints about their Ambient mode either – it allowed me to hold conversations effectively and piped in sound from the outside world in a natural manner. The digital assistant was the only function that gave me trouble. Firing up Google Assistant became frustrating at times due to the assigned input gesture not always working. When it did pop up, certain words were misinterpreted and minor inquiries like “what is my next event” lead to different actions (why it pulled up my alarm screen was baffling). Siri was more difficult to activate, and it stopped working on my MacBook Pro after one try. The Denon use Bluetooth 5.0 for connectivity, which is decent enough – but codec compatibility extends only as far as SBC and AAC, which really isn’t. Still, it’s efficient enough to deliver a battery life of near enough five hours from the earbuds with another four charges in the case – that with noise-cancelling engaged. Switch it off and the numbers rise to an all-in total of around thirty hours, with the ‘buds accounting for six hours of that. Charging is via USB-C – there’s no facility for wireless charging here. 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, the Apple AirPods equivalent.Music can be played via Bluetooth 5.0. Besides the standard SBC, Denon just offers AAC as a high-quality codec alternative. A choice appreciated by iPhone users, while Android fans who want to use one of the latest aptX variants might feel a bit of a disappointment. Once it’s piped aboard, sound is delivered by a couple of biggish (11mm x 10mm) oval full-range drivers. Interface The AH-C830NCW greatest strength is the way it delivers music. Respectable ANC and call quality also make it a serviceable pair of wireless earbuds for brand enthusiasts, or anyone seeking relatively affordable AirPods alternatives. They’re equally skillfully balanced elsewhere, too. The midrange fidelity during serpentwithfeet’s Wrong Tree is outstanding – poised, brimming with detail and utterly believable. The top of the frequency range, too, is nicely judged, with enough substance to offset the bit and shine these Denon earbuds can generate. Rhythmic expression is equally good, and the earbuds build a big, focussed soundstage that’s explicitly laid out and simple to understand. In terms of features and specifications, the Denon AH-C830NCW seems to deliver good value for frequent travelers. However, most people who are interested in in-earbuds will probably find alternatives in view of the too silverish and not very groovy sound, the clumsy handling and the not always secure fit. First and foremost, the cheaper JBL Tune 230NC TWS, which offers less resolution, but otherwise can actually do everything better than the Denon. Those who want more audiophile tuning and more isolating noise-canceling will probably be happy to pay the small premium for the Panasonic RZ-S500W. Specifications Denon AH-C830NCW

I put Denon’s ANC up against the very best: The Apple AirPods Pro, Bose QuietComfort Earbuds, and Sony WF-1000XM4, and it was almost impossible to tell the difference. The Denons produce a very slight hiss when you’re not listening to music, and there’s not much in the way of external sounds to cancel, but otherwise, they do an excellent job of keeping things nice and quiet. Sennheiser CX Plus True Wireless: A more secure fit, tons of app-based customizations, volume control, plus sound and ANC quality that matches the Denons.The AH-C830NCW doesn’t come with a full suite of controls (there is no on-board function for volume, for example). During my early testing, I thought that these Denon earbuds didn't include digital assistance support. However, it turns out the feature is supported but just rather poorly executed. The mic sounds average. We understood every word from a recording in the Voice Memos app on an iPhone, but as is typical, some Bluetooth audio artifacts detract from the quality. Nonetheless, the signal is strong enough and you shouldn't have any issues being heard clearly calls. An Average Entrant With Accurate Audio You’ll be able to discern instruments on orchestral masterpieces like Quincy Jones’“Soul Bossa Nova,” where brass arrangements and percussive elements like the striking congas are reproduced perfectly. My greatest joy came from indulging in jazz records. The melodic touch on Ahmad Jamal Trio’s “Dolphin Dance” was certainly felt, delivering double bass with such delicacy and steady hi-hats that tap gently on the eardrum. Rated to IPX4 standard, these earphones are tough enough to cope with a sweaty workout or being caught in a rain shower. Although tough, the AH-C830NCW’s are also comfortable. Light, compact and supplied with three sizes of silicone eartips, they easily fit most.
