The AH-C620R, available in black and white, is the most compact and lightweight Denon In Ear headphone. It uses an 11.5mm driver, mounted in housings combining die-cast aluminum and resin, designed for rigidity and vibration-damping. Denon Acoustic Optimiser technology helps equalizing the air-pressure in front of and behind the driver. It's all part of making the sound as dynamic and distortion-free as possible. The AH-C620R comes complete with a high quality cable and a 3-button remote controller including a microphone, letting you control music functions for your iPhone such as Play/Pause, Forward, Rewind, or Volume. Moreover, you can also use them to answer an incoming call or end the call. For optimum wearing comfort, the AH-C620R is ergonomically shaped to fit snugly into your ears and reduce stress. ;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-C620R is fitted with Comply TX400 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. ;To round up, the AH-C620R 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 play listing, and allows the user to access over 70,000 radio stations and 2 million on-demand programs via the TuneIn Internet Radio platform.
