• New Denon buds have 12mm drivers and a choice of open or ANC models
• Denon AH-C500W open earbuds are £99 / $99 (about AU$208)
• Denon AH-C840NCW ANC earbuds are £159 / $159 (about AU$334)

Denon has announced two pairs of true wireless earbuds; one with an open-ear design for environmental awareness, and one with hybrid active noise cancellation and transparency modes.

The new Denon AH-C500W and Denon AH-C840NCW earbuds come with Bluetooth LE Audio, Auracast and multi-point pairing, and they're both rated IPX4 for water resistance. Both offer strong battery life and feature Denon's 'FreeEdge' 12mm drivers.

These should be very impressive earbuds: we've previously reviewed the AH-C830NCW from 2022 and we really loved the sound quality. Our only major gripe was the "unremarkable" noise cancellation of those ANC buds, and Denon's had three years to work on that to rival the best noise cancelling earbuds.

Choose your fit

The open earbuds are the Denon AH-C500W, and they promise up to 24 hours of listening time from a single charge with a fast charge adding an extra hour of playback in just 10 minutes. The drivers are 12mm and there are dual microphones in each bud for clear calls.

They're open-ear in the same sense as the AirPods 4 are – they sit just outside the ear canal, with no tip inserted inside (unlike many of the best open earbuds that leave a bigger gap between your ear and the speaker). And then the ANC buds, the AH-C840NCW, are like the AirPods Pro 2 (and most of the best earbuds) in that they're a similar design but with the in-ear isolating tips.

The ANC buds, the AH-C840NCW, use their charging case to deliver battery life of 35 total hours, and they charge faster than their siblings: the extra hour of playback takes just five minutes from flat. There are three eartip sizes included.

The pair have similar designs to the AirPods models referenced above, but have two tempting elements that make them a great alternative. The first is more likely useful for Android users, and it's Bluetooth LE Audio support, which is capable of higher quality and better stability than regular Bluetooth (though support is still thin on the ground). Bluetooth Auracast support is also nice as a future-proofed option.

The other element is the price. The AH-C500W are £99 / $99 (about AU$208) and the AH-C840NCW are £159 / $159 (about AU$334). These are the kinds of prices that AirPods fall to when they hit record-low prices, so by having these as a starting price, Denon has a nice edge. Both sets of buds will be available to buy from 15 April 2025.
