With a lightweight honeycomb aluminum casing, these open-air headphones produce no sense of pressure on the ears, offering a completely natural listening experience. Newly designed 53 mm drivers with bobbin-wound CCAW voice coils deliver spacious sound with superior highs and mids. The self-adjusting wing support automatically adjusts to your head size for easy-wearing listening comfort. A straight cord at the left earpiece terminates to a mini plug with the included 1/4" adapter.
