This Bundle Includes:
50 x Q-Audio QSD-3PRO Silent Disco Headset Receiver
1 x Q-Audio SD-CH48 Silent Disco 48-Way Charger
1 x Q-Audio QSD-3PRO TX+ Bluetooth Silent Disco Transmitter

This Q-Audio 50-Way Silent Disco Bundle with Bluetooth Transmitter and Charger is a larger wireless headphone system for silent disco events, schools, fitness classes, wellness sessions, guided tours, conferences, exhibitions, corporate AV, venues and event hire users. With 50 QSD-3PRO headset receivers, the QSD-3PRO TX+ Bluetooth transmitter and the SD-CH48 high capacity charger included, this package is ideal for organisers needing a scalable silent listening system for bigger groups.

The 50 included QSD-3PRO headset receivers are designed to deliver music or speech directly to each listener without the need for loudspeakers. This makes the system useful for noise-sensitive venues, shared spaces, schools, hotels, gyms, studios, outdoor classes and event environments where clear audio is needed without disturbing other people nearby.

Each QSD-3PRO headset receiver features 3 selectable channels within the CH70 band, operating between 863 and 865MHz. Integrated red, green and blue LED indicators show the active channel, helping organisers quickly see which audio feed each listener is using. Individual volume control on each headset also allows every user to set their own comfortable listening level.

The QSD-3PRO TX+ transmitter gives the bundle a professional and flexible audio input point. Bluetooth pairing allows quick wireless playback from compatible devices, while the balanced stereo XLR/combi jack inputs make it suitable for DJ mixers, controllers, sound desks, media players and AV equipment. This means the bundle can be used for both straightforward music playback and more professional event setups.

A 1/8 inch microphone input on the TX+ allows voice announcements to be mixed into the transmitted audio, making the system practical for instructors, tour guides, teachers, hosts and presenters. This adds extra value for fitness sessions, guided tours, school activities, exhibitions, conferences and corporate events where spoken instructions need to be heard clearly by every participant.

The system supports 3 selectable channels, with up to 3 transmitters able to be used together when additional audio feeds are required. One TX+ transmitter is included in this bundle, providing one audio feed as supplied, with the option to expand later by adding more compatible transmitters for multi-channel silent disco events, language options or separate listening zones.

The included SD-CH48 charger is a high capacity charging system for QSD-3PRO headset receivers. It provides 48 USB-C charging outputs using a 12-port USB power supply and twelve 4-way USB-A to USB-C splitter cables. This allows 48 of the 50 included headsets to be charged at the same time, with the remaining two headsets charged separately or in a second charging cycle. For larger systems, this still gives a practical and organised charging solution while keeping the package compact and easy to manage.

Each QSD-3PRO headset charges via USB-C, with a full charge taking approximately 3 hours and battery life of around 8 to 10 hours. This makes the bundle suitable for regular events, classes and professional use where multiple headsets need to be charged, prepared and ready for repeat sessions.

Best for silent disco parties, wedding entertainment, schools, colleges, fitness instructors, wellness classes, guided tours, museums, conferences, exhibitions, corporate AV, event organisers, hire companies and venues needing a larger 50 headset silent disco system with Bluetooth transmitter and high capacity charging.
