General description

The Wireless Headphone System CIC-336/UT/UR allows for diffusion of broadcast and entertainment signals to several wireless headphones in closed spaces.

The headphone system provides operators with a protection against background noise, as the receiver circuit is mounted within a structure that reduces outside noise considerably.

The system consists of a transmitter unit (336/UT) and several receiver units (336/UR).
