Ultrasone PROline 650   
High SPL, High Isolation S-Logic Stereo Headphones

Ultrasone PROline 650 headphones are rooted in the legendary HFI-650 by using the same high class gold-plated drivers. Due to the new design PROline 650 offers an even more spectacular open three-dimensional image with a maximum of transparency. Thanks to its closed construction, external noise is suppressed.

The PROline-650's have a frequency response of 10Hz to 25kHz and deliver a max SPL of 95dB. Like all Ultrasone headphones, the PROline 650 incorporates their patented S-Logic technology to produce a natural three dimensional sensation while ensuring hours of fatigue free listening. Ultrasone implemented an additional function which enables you to fold these headphones for a compact storage and easy transportation in a suitcase.

Much like toothbrushes and underwear, headphones cannot be returned or exchanged.
