## Description

Product description No Lip-sync Delay The Quartet's RF 2.4Ghz technology reduces the audio lag down to as low as 7ms and allows you and your whole party to experience no lip-sync delay, no matter how many devices are connected. Individual Volume Control Each pair of Quartet headphones is able to increase and decrease its own volume without affecting the volume levels of any other connected headphones. Clear Voice Mode This built-in mode reduces background noises and increases voice volumes, so you'll be sure to never miss a word. Before You Buy, Please Note That... The Quartet-Extra is a single pair of 2.4Ghz wireless headphones designed to be used with the Avantree Quartet bundle (sold separately). It will only work with the Quartet transmitter and will NOT work with other 2.4G transmitters.

## Features

- [ONLY WORKS WITH QUARTET] This single pair of 2.4G wireless headphones is an add-on for the Avantree Quartet bundle (sold separately). Add up to 100 of these headphones to the Quartet bundle and enjoy an outdoor movie or silent concert without disturbing the neighbors.
- [LESS DELAYS, BETTER QUALITY] The Quartet-Extra headphones feature 2.4G technology and NOT Bluetooth. This reduces the audio lag down to ~30ms -- significantly less than the 220ms of standard Bluetooth and even the 40ms of aptX Low Latency. This also improves overall sound quality due to 2.4G's higher bit rate & extended bandwidth.
- [INDIVIDUAL VOLUME CONTROL] Each pair of wireless headphones are equipped with built-in individual volume controls, so everyone can listen at their own desired volume.
- [LIGHTWEIGHT & COMFORTABLE] These headphones are ergonomically designed to be lightweight and flexible, featuring soft memory foam earpads and an adjustable headband. Enjoy all-day, pressure-free use. NOTE: Replaceable earpads are available for purchase.
- [EXTENDED PLAYTIME] With a battery life of up to 20 hours, these headphones will last through your longest movie or concert sessions with time to spare.
