Benefits & Use Cases
The Avantree Quartet 2 is engineered for reliable, multi-user audio sharing across diverse environments. In home theaters, it allows multiple family members to enjoy movies or shows at their preferred volume levels without disturbing each other. Classrooms benefit from simultaneous listening during lectures or language instruction, while churches can broadcast sermons or choir performances clearly throughout services. The system also supports silent disco setups where guests dance to shared music through private headsets. Its compatibility with optical and AUX inputs ensures broad support for older and newer AV equipment alike.
Important Notes
The Quartet 2 uses proprietary 2.4GHz wireless technology rather than standard Bluetooth, meaning the included headphones cannot connect directly to smartphones, tablets, or other Bluetooth devices outside the system. They are designed exclusively to pair with the included transmitter. For maximum performance, ensure the transmitter and headphones remain within their operational range—up to 30 feet indoors and 100 feet outdoors under ideal conditions. The package includes the transmitter unit and four headphones; additional accessories or expansion units must be purchased separately. Care should be taken to avoid physical obstructions or interference from other electronic devices when deploying the system over longer distances.


Regulate the quantity on every pair of headphones independently of the others with built-in controls.

Pay attention by means of each an exterior soundbar and the Quartet 2 headphones concurrently.
