The Hamilton Buhl W904-MULTI is a four-user wireless listening system ideal for use in schools and other institutions. The system consists of a W900-Multi wireless transmitter and four pairs of W901-Multi wireless headphones. The system has four selectable color-coded operating frequencies.
The transmitter can connect to any audio source with a 3.5 mm jack, such as a tape player, CD player, VCR, DVD player, computer, or television. It then uses a VHF signal to transmit the audio to any headphones set to the same color-coded frequency within a 300 ft range.
The headphones have a fully adjustable headband and thickly cushioned earcups to provide a great fit with long-lasting comfort. The internal NiMH battery provides up to 50 hours of operation on an eight-hour charge. LED charging lights indicate when the headphones are fully charged.
