Koss HB70 headphones are all the Sound of Koss without the wires. These single-channel wireless headphones and compact infrared transmitter incorporate state-of-the-art infrared (IR) technology ideal for home audio, video, and computer use. Let the music truly set you free. 

Unlike conventional wireless systems, the HB70 system features a compact, lightweight design. The transmitter connects to most home systems through a 3.5 mm headphone jack (or audio output) and transmits an invisible, infrared signal to the wireless headphones, which reproduce the audio signal. A behind-the-head headband design makes wearing the HB70s comfortable, while foam ear cushions provide an airy sound allowing you to stay in touch with your environment. A volume control on the ear cup makes level adjustment convenient and easy. Untether yourself from your music with wireless audio and indulge in a cordless experience with Koss.
