Silent Disco Headphones – 3 Selectable Channels – 863-865MHz. Stereo headphone receiver for QSD silent disco system featuring 3-selectable channels within the CH70 band and individual volume control.
Pair multiple receivers to either the QSD-3PROTX or QSD-3PROBTX for a scalable wireless audio headset system and charge multiple headsets simultaneously with the SD-CH20 or SD-CH48 charging units.

The Q-Audio QSD-3PRO is a 3-channel silent disco headphone system, featuring integrated red, green, and blue LED indicators to clearly denote the active audio channel. Engineered specifically for silent disco applications, these headphones operate independently of other wireless devices in the environment, thanks to robust RF architecture. They utilise the licence-free CH70 spectrum, transmitting on 863–865 MHz for reliable, interference-free performance. The QSD-3PRO is equipped with soft, ergonomically designed padded ear cushions and an integrated volume control for user comfort and convenience. Power is supplied via a built-in rechargeable battery, which charges through a USB-C interface. Full charge time is approximately three hours. The system is fully compatible with Q-Audio’s new 20-way and 48-way USB-C multi-chargers, offering efficient large-scale charging solutions ideal for professional event deployment. Designed for versatility, the QSD-3PRO is ideal for a range of applications beyond silent discos. It is well-suited to conferences, exhibitions, and corporate events where background noise or shared spaces can interfere with audio clarity. By delivering direct-to-ear sound without external amplification, the system ensures clear, uninterrupted communication in noisy or acoustically challenging environments.
