Product Overview
The Avantree Quartet 2 is a wireless group listening system designed for shared audio experiences in environments such as homes, classrooms, churches, and silent discos. It consists of a transmitter that connects to audio sources like TVs, soundbars, or mixers and broadcasts high-quality sound to up to four compatible headphones simultaneously. Ideal for families, educators, worship leaders, and event organizers, this plug-and-play solution ensures everyone hears clearly with minimal setup. The system supports scalable use—expandable to hundreds of users with additional compatible headsets—making it suitable for both small gatherings and large-scale events. With low-latency performance and intuitive volume controls, the Quartet 2 delivers reliable, synchronized audio without delay.
Key Features

- Plug & Play Setup: No complex pairing required—simply connect the transmitter to your audio source via optical, AUX, or Bluetooth input. Once connected, all headphones sync automatically and begin receiving audio immediately.

Benefits & Use Cases
The Avanttree Quartet 2 excels in scenarios requiring shared audio access across multiple individuals. In educational settings, teachers can distribute headphones to students during lessons without disturbing others. At home, parents and children can enjoy films together while maintaining separate volume levels. Churches benefit from integrating a microphone into the system so sermons or announcements broadcast clearly through all headsets. For private events like silent discos or movie screenings, the expandable nature allows dozens of guests to participate using compatible headphones. Its compatibility with standard AV equipment ensures easy integration into existing setups.
Important Notes
- This system uses 2.4GHz wireless technology rather than Bluetooth; the headphones do not pair directly with phones or tablets and must connect exclusively through the included transmitter.
- Maximum effective range between transmitter and each headset is approximately 10 meters indoors; outdoor performance may vary based on obstructions.
- To support microphone input for public address functions (e.g., church or classroom), plug a wireless mic receiver into the AUX port of the transmitter.
- Package includes one transmitter and four headphones; additional headsets sold separately.
- For simultaneous use with a soundbar, connect both devices to the transmitter—audio will play through both outputs at the same time.
