1. Ensure Quartet Transmitter is On: Verify that your Avantree Quartet transmitter (sold separately) is powered on and actively transmitting audio.
2. Power On Headphones: Press and hold the power button on the Avantree Quartet-Extra headphones until the indicator light illuminates.

Operating Instructions

Power On/Off

• To Power On: Press and hold the power button located on the headphone earcup for approximately 3 seconds until the LED indicator lights up.
• To Power Off: Press and hold the power button for approximately 3 seconds until the LED indicator turns off.

Volume Control

Each pair of Avantree Quartet-Extra headphones is equipped with independent volume controls. This allows every listener to adjust their audio level without affecting others connected to the same Quartet system.

• Increase Volume: Use the '+' button on the headphone earcup.
• Decrease Volume: Use the '-' button on the headphone earcup.

Charging the Headphones

To charge your headphones, connect the provided charging cable to the charging port on the headphones and a standard USB power source. A full charge takes approximately 2 hours and provides up to 20 hours of playtime.

EQ Modes

The headphones feature two Equalizer (EQ) modes to optimize your listening experience:

• Voice Clear Mode: Enhances vocal clarity, ideal for dialogue-heavy content like news or talk shows.
• Balanced Sound Mode: Provides a well-rounded audio profile suitable for music and general entertainment.

Switch between these modes using the dedicated EQ button on the headphones to match your audio preference.

Key Features

• 2.4G RF Wireless Technology: Unlike Bluetooth, the 2.4G RF technology significantly reduces audio latency to approximately 30ms. This ensures audio and video remain synchronized, eliminating lip-sync delay during TV watching. This technology also supports a higher bit rate and extended bandwidth for improved sound quality.
• Lightweight and Comfortable Design: The headphones are ergonomically designed with soft memory foam earpads and an adjustable headband, providing comfort for prolonged listening sessions. Replaceable earpads are available for purchase to maintain hygiene and comfort over time.
• Extended Playtime: A single charge provides up to 20 hours of continuous audio playback, ensuring long-lasting performance for movies, music, or other audio content.
