Enjoy rich, accurate sound through your portable CD or MP3 player using the Koss KSC75 on-the-go headphones. Designed for people who want a lightweight listening solution without sacrificing audio quality, the phones employ a pair of sport clips to fit neatly around each ear, thus eliminating the constraints of conventional headbands. As a result, listeners can wear the phones--which weigh a mere 1.5 ounces--without disturbing their carefully coifed hairdos. When not in use, the headphones store compactly in a backpack or purse without taking up unnecessary space. Meanwhile, the phones produce terrific sound through their titanium-coated high-polymer drivers, which are built for maximum precision, as are the bass-boosting neodymium iron boron magnets. Their combined efforts generate a noteworthy 15 Hz to 25 kHz frequency response.
