Featuring Denon's latest in-ear headphone technologies, the AH-C360 comes equipped with our exclusive Radial Cascade Damper system which minimizes cable-transmitted vibration noise for superior fidelity while on-the-go. Denon's Acoustic Optimizer technology balances the sound pressure in front of and behind the diaphragm delivering neutral tonal balance with superior deep bass detail. The lightweight in-ear headphone housing features Denon's hybrid material driver system which incorporates a soft elastomer outer layer for optimum comfort. The in-ear design ensures a comfortable fit, and the AH-C360 is supplied with four sets of soft, compliant silicon earpads that allow the best fit and optimum isolation from extraneous ambient noise. The headphones also feature Oxygen Free Copper cabling, and are supplied with an extension cable that features an L-shaped 3.5mm gold-plated plug that is iPhone compatible. The included semi-hard shell carrying case is compact and lightweight.
