Designed for incredibly comfortable listening. With a lightweight honeycomb aluminum casing and magnesium frame structure, these open-air headphones produce no sense of pressure on the ears, offering a completely natural listening experience. Newly designed 53 mm drivers with CCAW voice coils reproduce remarkably natural sound, with impactful bass and outstanding vocal projection. The self-adjusting wing support automatically adjusts to your head size. A straight OFC cable at the left earpiece terminates to a mini plug with included 1/4" adapter.
