The HB70 Infrared (line of sight) Stereophone system consists of a single channel wireless stereophone & a compact infrared transmitter.
Incorporating infrared technology, the HB70 is ideal for home audio, video & computer use.
The transmitter connects to most home systems through a 3.5mm headphone jack or audio output.
Utilizing infrared (IR) technology, it transmits an invisible, infrared signal to the headphone which then reproduces the audio signal.

When a conventional headband is too cumbersome, the HB70 behind-the-head stereophone provides maximum comfort during extended wearing periods while providing the same excellent Sound of Koss.
A volume control is placed on the earcup for convenient level adjustment.
Foam cushions rest on the ear & provide an open, airy sound that allows the user to stay in touch w/their environment.
