The transmitter can be set to one of four color-coded frequencies (blue, yellow, green, and orange). Simply connect the transmitter to any audio source that has a standard 3.5mm mini jack, such as a tape player, CD player, TV, or computer, and the transmitter will use a VHF signal to send the audio to an infinite number of compatible headphones within a 300' range.
