AH-C820 Powerful Dual Driver In-Ear Headphones


Drawing on half a century of Denon headphone engineering experience, the new 2016 models are designed to combine comfort with no-compromise sound. Aimed at those who want the very best sound whether travelling, working or relaxing, the new in-ear models are packed with advanced Denon technologies, designed to deliver the best possible performance from compact, lightweight earphones.


Double Air Compression Driver™

The range-topping AH-C820 incorporates Denon’s unique Double Air Compression Driver™ technology for powerful bass and ultimate clarity. It uses two 11.5 drivers, one in front of the other, to move more air and thus deliver powerful, low-distortion bass. This patented design also uses separate wires from the plug to each driver, for ultimate signal purity – another Denon world-first. The drivers are mounted in housings combining die-cast aluminium and resin, designed for rigidity and vibration-damping, while dual Denon Acoustic Optimiser ports to the front and rear of the housing help equalize the air-pressure in front of and behind the drivers. It’s all part of making the sound as dynamic and distortion-free as possible.


Radial Cascade Damper system, goodbye cable noise

Audio enthusiasts often complain about the noise generated from the cable rubbing against their chest when they’re moving. Denon’s specially designed Radial Cascade Damper system reduces cable-transmitted vibration noise, enabling you to enjoy studio-quality music on the go. In addition, the AH-C820 is fitted with Comply TX500 ear-tips, which combine with the ergonomically-shaped housings to give a secure fit for the purest sound and maximum isolation from external noise. The tips use memory foam activated by the heat of the user’s ears, and have an integral wax-guard to keep the inside of the earphones clean. Four sizes of silicon ear-tips are also provided, along with a carrying case and cable clip.

Optimising sound with the dedicated Denon Audio Application

To round up, the AH-C820 can be used with the dedicated Denon Audio Application for iOS and Android, allowing you to enhance the sound and tune it to suite your personal preferences. This app not only optimises the sound of portable devices, it also offers an improved player interface supporting queuing, and playlisting, and allows the user to access over 70,000 radio stations and 2 million on-demand programs via the TuneIn Internet Radio platform.

Awards & Reviews - AH-C820

VGP Lifestyle 2019
Denon C820 Earphones highly reviewed by The Gadgeteer's

"These headphones are impressive. Even at reasonable volumes the bass booms. In fact, I had an odd sensation during a particularly bass-filled passage. The specs indicate full spectrum sound down to 4Hz and Denon wasn’t kidding."
