Our single-sided mono headphone is designed for individuals who are listening to lectures, extended instructions, or other spoken words with the aid of a personal receiver. The ER1 is ideal for use in tour groups, by those needing additional audio reinforcement in classes or larger lecture halls, or for when a smaller group within an audience is being served by a translator.

Lightweight and comfortable to wear, the hook of the ER1 rests around the top of the right ear while the jack connects into one of the dual 3.5mm headphone plugs on the WS-R receiver. The volume is controlled from the audio source.
