- On your device (phone, PC, Bluetooth-enabled TV), go to Bluetooth settings and search for new devices.
- Select "Avantree Loop Dock" from the list of available devices.
- Once connected, the LED indicator on the earbuds will flash blue slowly.
2.3 Auracast Connection
The Avantree Loop Dock is Auracast-enabled, allowing connection to Auracast transmitters and audio sources. Refer to your Auracast transmitter's manual for specific pairing instructions. The earbuds will automatically detect and connect to available Auracast broadcasts.

The Avantree Loop Dock connects to various Auracast transmitters from different brands, including Avantree's own ecosystem.
2.4 TV Compatibility Note
These earbuds are designed for TVs and devices with built-in Bluetooth audio. If your TV only outputs sound via HDMI ARC/eARC, Optical, or AUX, direct connection is not possible. In such cases, an external Bluetooth or Auracast transmitter (e.g., Avantree Aura Loop) is required to connect your TV to the earbuds.

This diagram shows that the Loop Dock connects directly to Bluetooth-enabled TVs but requires a transmitter for non-Bluetooth TVs.
