Getting great sound out of a portable audio device has never been easier thanks to Koss TM602 headphones. Koss's over the head headphones have an 88-dB sensitivity rating, a frequency response range of 100 Hz to 18 KHz, and 32-ohm impedance. Those features mean that the Koss headphones can provide clear sounds from numerous devices. Intense bass notes and beautiful tones in higher registers sound perfect thanks to the careful engineering behind the Koss TM602 headphones. Koss's over the head headphones, however, offer more than just on-the-go listening. While the Koss headphones come with a standard 1/8-inch (3.5 mm) connection used in most portable devices (MP3 players, smartphones, tablets, etc), they also come with a 1/4-inch (6.3 mm) connection that fits most home stereos. A 4-foot cable built into the headphones lets listeners enjoy music, audiobooks, and other audio media without feeling constrained. With Koss TM602 headphones, practically anyone can enjoy audio recordings privately whether they are at home or in public.
