Within the construction of the ear cup, our specially designed acoustical porting allows both drivers to move freely, increasing the bass and reducing distortion. The new Crusher draws its power from a premium battery (AA) powered amp hidden in the ear cup. The bass sensation slider on the left ear cup allows you to adjust the sensation levels to your preference or playlist. When your music stops or the headphone is unplugged from a source during play, the amp will power off within 10 seconds. Crusher incorporates dual ear cup articulation and a precise selection of materials to deliver long-lasting comfort without affecting sound quality. Crusher features a foldable hinge design that breaks down to 40 percent its size. Toss it in the included microfiber travel bag, and your headphone is in safekeeping for wherever you take it next. The Crusher's detachable cable serves multiple purposes - it eliminates cable tangling, increases longetivity, customizes your look, upgrades your mic and can be used as an AUX cord for other devices.
