It uses an 11.5mm driver, mounted in housings combining die-cast aluminum and resin, designed for rigidity and vibration-damping. 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. Moreover, you can also use them to answer an incoming call or end the call. In addition, the AH-C620R is fitted with Comply T X400 ear-tips, which combine with the ergonomically-shaped housings to give a secure fit.

Four sizes of silicon ear-tips are also provided, along with a carrying case and cable clip.
