KOSS Black/Silver KSC17 (163585) 3.5mm Connector Supra-aural Collapsible Stereo Headphone

The ultra-light KSC17 Stereophone delivers high quality sound in a behind-the-head design that folds into an ultra-compact configuration that tucks neatly into a gym bag, backpack, or briefcase. Dynamic elements, constructed from mylar for enhanced rigidity, minimize mechanical distortion and yield a full frequency response from 40-20,000 Hz. Neodymium iron boron rare earth magnet structures enable the KSC17 to deliver greater volume, even with low-voltage portable devices. Oxygen-free copper voice coils improve signal transmission and conduction for cleaner, clearer sound. Foam ear cushions provide an open, hear-through sound that lets listeners stay in touch with the world around them, perfect for working out, navigating the city, or listening at the office.
