The Sennheiser HD 215 is a set of dynamic headphones designed especially for the Dj who wants function as well as good sound. Rotatable ear cups are essential for the dj to wear in different ways for performing different mixing functions. Closed, circum-aural design means the headphones completely cover the ear, thus keeping sound in and ambient noise out, important for mixing in noisy environments. A protective pouch is included for storage and travel, and the cable is one-sided and detachable, only connecting to one side to power both speakers. These are the next step up from the more basic HD 205 Dj headphones and as such they have an improved Frequency Response and less Total Harmonic Distortion(THD). This means deeper bass and higher treble response as well as less distortion of the audio signal. The detachable cord is also an extra feature of the HD 215.
