Part of Denon's Acoustic Luxury series, the AH-260 in-ear headphones combine our latest technologies to deliver optimum sound quality and superior comfort. Denon's Acoustic Optimizer system provides equal ambient air pressure on both sides of the diaphragm for naturally balanced sound. Our exclusive Radial Cascade Damper system reduces cable transmitted vibration, and the cable features Oxygen Free Copper wire. The earpiece housings are constructed of a hybrid Aluminum and resin compound to dramatically reduce resonance improving sound detail and balanced. The large 9mm diaphragms are driven by powerful Neodymium magnets for dynamic sound and high efficiency, extending the battery life of your portable music player or computer. To ensure optimum fit and comfort, the AH-C260 comes with four sets of compliant ear pads that allow the best match for any ear. The ear pads are super soft, and allow maximum isolation from external noise, as well as supreme comfort even with extended listening sessions. The 1.3 meter (4½ feet) cable features equal length (left/right) earpiece cables, along with an adjustable branch point adjustment slider, as well as a cable clip. A compact soft shell carrying case is included.
