A 3-channel pair of silent disco headphones loaded with red, green and blue LED indicator lights that let you know which one of the three channels is active. Specifically designed for silent disco, the W Audio SDPRO headphones are unaffected by other wireless transmitters in the room and feature soft padded, comfortable ear cushions with built-in volume control. Charging the internal battery takes around 3 hours using the multi-charger (not included), after which the user may roam free around the event space selecting their favourite music source. The RF transmission system operates on 863-865Mhz in the license free CH70 spectrum.
