The black Crusher Over-Ear Headphones from Skullcandy feature an active bass boost amplifier built into the earcups that provides adjustable bass control over your music. The over-ear earcups house both bass extension and standard drivers within acoustical porting that is designed to increase bass response and reduce distortion.
The built-in amplifier is powered by a single AA battery for up to 40 hours of playback and features an Auto On/Off Smart Circuit that automatically turns the amp off when you unplug your headphones or when no audio is sensed for 10 seconds. The headphones themselves have an ergonomic design and leather ear pillows for comfort during extended listening sessions. The in-line single-button remote and mic allow you to control playback and take calls. You can fold the Crushers for storage in the included microfiber travel bag.
