Koss KSC24

The Koss KSC24 are Behind-the-Head headphones designed for a user on the go looking for portability as well as sound quality.  Its lightweight 2 ounce and fully collapsible design make it ideal to be packed into a gym bag or briefcase.  The adjustable headband accomodates all head shapes, and will not interfere with hats or helmets.  Dynamic elements made of mylar minimize mechanical distortion and give the KSC24 a frequency response of 18-22,000 Hz.  This is a much wider range than the 40-20,000 Hz produced by the remainder of Koss' behind-the-head models, which gives the KSC24 deeper bass and and a overall clearer sound. Neodymium iron boron rare earth magnet gives them higher output volumes, even from low-voltage portable devices.  The included foam earpads allow users to still hear the world around them, making them ideal for work-outs, navigating the city or use at the office.  The KSC17 has a 4 foot single entry cord, with L-shaped standard 3.5mm (1/8") plug.
