The Quartet-Extra is a single pair of 2.4GHz wireless headphones designed to be used as an add-on for the Avantree Quartet bundle (sold separately). Unlike other 2.4G transmitters, it will only work with the Quartet transmitter and not with other devices. This single pair can be connected to the Quartet bundle, allowing you to add up to 100 headphones to create an immersive, wireless audio experience for outdoor movies, silent concerts, or other shared viewing experiences without disturbing the neighbors.

Compared to standard Bluetooth, the Quartet-Extra headphones feature 2.4G technology, which reduces audio lag to as low as 7ms - significantly less than the 220ms of standard Bluetooth and even the 40ms of aptX Low Latency. This improved latency, along with the higher bitrate and extended bandwidth of 2.4G, also enhances the overall sound quality.

Each pair of Quartet-Extra headphones is equipped with built-in individual volume controls, allowing everyone to listen at their preferred volume without affecting the levels of other connected headphones. This provides a personalized listening experience for each user.

Designed for comfort and all-day use, the Quartet-Extra headphones feature an ergonomic, lightweight, and flexible construction with soft memory foam earpads and an adjustable headband. Replacement earpads are also available for purchase.

With a battery life of up to 20 hours, these headphones can power through your longest movie marathons or concert sessions, ensuring you can enjoy uninterrupted audio without the need for frequent recharging.

In addition to the Quartet-Extra, the Avantree Quartet bundle includes a 2.4GHz wireless transmitter and four pairs of headphones. This bundle allows you to create a multi-user wireless audio setup, enabling up to 100 headphones to be connected simultaneously. The Quartet bundle also supports pass-through mode, allowing you to listen on the headphones while your speaker system remains active.

The Quartet-Extra headphones are compatible with a variety of audio inputs, including optical, 3.5mm, and RCA, making them versatile for use with smart TVs and other entertainment systems.

Customer reviews of the Quartet-Extra and the Quartet bundle are overwhelmingly positive, with average ratings of 4.4 out of 5 stars and 4.5 out of 5 stars, respectively. Users have praised the low latency, clear audio quality, and the ability to create a personalized, wireless listening experience for multiple users.

In summary, the Quartet-Extra wireless headphones and the Avantree Quartet bundle offer a versatile and high-quality solution for shared audio experiences, with features like low latency, individual volume control, and extended battery life, all designed to enhance the overall user experience.
