Bass You Can FeelSkullcandy goes out of their way to make bass that you can feel a physical sensation with the Crusher Headphones. The custom REX40TM coupled with the Sensation55TM drivers deliver pulse-pounding bass experience like a pair of subs in the trunk of a low-rider. Ported to deliver the deepest bass, with an amplifier built-in directly to the earcup instead of a bulky inline amp. Control the bass from a single position on the outside of the Crushers for as much low-frequency love that you can handle.Durable construction to take the day-to-day use and with a foldable hinge to store in the included microfiber carrying case. The detachable cable includes the singe button Mic1 remote for control of most smartphones. Take calls or listen to music all with a single button press.
