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.

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.
