Denon AH-C830NCW True Wireless In-Ear Headphones with Active Noise Cancelling, Water Resistant Earbuds with Crystal Clear Call Quality

Product Information

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. Soundcore Liberty 3 Pro: Better battery life, wireless charging, customizations, and hi-res audio on Android devices, but ANC isn’t as good. The sound quality is the biggest thing that I love about these little buds. It’s perfectly balanced, so there’ll be no need to use any kind of equalizer. It’s not earth-shattering, let’s get that out of the way, but it is very surprising when you first play something through them. Sub bass is more punchy and present than with other in-ear buds, without drowning out the crisp, tingly highs. 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.

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. That also doesn't bode well when you want to get active. Denon gave these earbuds an IPX4 rating, which is passable for sweat and water resistance, but hardly what I consider durable. The AirPods Pro have the same designation, so yet another thing these earbuds match them on, but if you are looking for something to break a sweat in, the best running and workout earbuds could be a place to start. 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.

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. 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. 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 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 Sound quality is where the Noise Cancelling Earbuds show their greatest strength: They sound fantastic.

The biggest difference between these 830s and their more affordable relatives is the appearance of active noise-cancellation. It’s a three-stage system, cycling through ‘on’, ‘off’ and ‘ambient’ (which gives a little boost to external sounds). There are a couple of mics in each earbud to assist the noise-cancelling processing, while a further three take care of call clarity. Here’s the problem, and it’s a weird one. Normally, I will be spending some time telling you about the additional features and customization potential granted by a companion app. But Denon does not have a companion app for its AH-C830NCWs.Supplied with a charging case, the Denon True 830 earphones have a total of up 24 hours charge. Enjoy up to 6 hours charge from the earphones without ANC activated and up to 4.8 hours with it switched on. 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.

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.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.

Denon promises up to six hours of listening time, extended to 24 with the case. That “up to” is doing a lot of heavy lifting in Denon’s claim, as that is with ANC turned off. And in those same testing conditions, the AH-C830NCWs live up to that promise — just over six hours of listening time. In 2022, releasing your earbuds without an app to control them is quite the own-goal. Denon AH-C830NCW: Battery life The AH-C830NCW express dynamic variations well too (the big shifts and the more minor harmonic variations as well), and do really good work with soundstages too. Laying out a symphony orchestra in a rational manner isn’t all that easy for even the most expensive earbuds, but there’s no mistaking where everyone’s sitting when the Denon buds describe it. Overall, calling on the Denon Noise Cancelling Earbuds is very good. External sounds are largely cancelled, and your voice will sound full, not thin and tinny, like it can with some earbuds. There were the occasional wobbles, as can happen with any earbuds, but I don’t think your callers will be bothered by it.

Who needs an app anyway?

This performance is typical of similarly priced competitors, but to Denon's credit, we didn't notice obvious changes to the sound signature when we turned on any of the ANC modes, which is a plus. In any case, it's easy to switch between the three ANC modes, and the transparent listening mode works reliably when you need to hear your surroundings. Controlled, Detailed Audio 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 Denon estimates the earpieces can last between 4.8 and 6 hours on battery depending on your use of ANC and volume. The case holds an additional 14 to 18 hours of charge.
