Avantree Quartet-Extra Add-On Headphones – 2.4G RF Wireless, Scalable to 100

Overview

Enhance any Avantree Quartet setup with the Quartet-Extra add-on headphones. This lightweight, comfortable pair is designed to work with the Quartet bundle (sold separately) and lets you expand group listening to a full audience—great for outdoor movies, silent concerts, or any shared space where quiet is key.

With a focus on reducing delays and improving clarity, Quartet-Extra is built for environments where everyone should be able to hear clearly without stepping on each other’s toes. The result is a more immersive experience for viewers, listeners, and performers alike, without the need to raise the volume for the entire room.

Compatibility and Performance

Note that these are add-on headphones and only function when paired with the Quartet system. They use 2.4G wireless rather than Bluetooth, which helps reduce audio lag and increase overall sound quality. Expect a smoother, more immediate listening experience thanks to the higher bit rate and wider bandwidth offered by the 2.4G connection.

Key Benefits

• 2.4G wireless, not Bluetooth: lower latency and higher bandwidth for crisper audio.
• Lower delays, better quality: latency around ~30 ms improves real-time listening compared with typical Bluetooth ranges.
• Scalability: add up to 100 headphones to a single Quartet bundle for larger events.

Comfort and Durability

• Lightweight & comfortable: ergonomic design with soft memory foam ear pads and an adjustable headband for all-day wear.
• Replaceable ear pads available if you want to refresh comfort or hygiene over time.

Power and Control

Enjoy long sessions with up to 20 hours of battery life per charge, making it easier to cover full movies, concerts, or multi-day events without frequent recharging. Each headset includes individual volume control so listeners can tailor their own listening level without impacting others.

Practical Scenarios

Ideal for family movie nights, silent discos, classrooms, or outdoor screenings where background noise matters. The Quartet-Extra helps you maintain a focused listening environment while keeping neighbors and nearby attendees undisturbed. While it is designed to work with the Quartet system, it remains a flexible choice for anyone seeking a scalable listening setup in compatible contexts.

Compatibility note: These headsets require the Quartet bundle to operate and are not standalone Bluetooth devices.
