FAQ

Can I use the Avantree Relay with my smartphone?

No, the Relay is designed specifically for 3.5mm audio-out sources like airplane seat jacks and is not compatible with phones or other devices that require bidirectional audio communication.

How do I connect two headphones simultaneously?

After plugging the adapter into the audio jack, put both headphones into pairing mode and follow the standard Bluetooth connection process; the Relay will automatically sync audio to both devices.

Is there any audio delay when using this adapter?

Latency depends on your headphones’ codec support; aptX Adaptive offers minimal delay, while standard Bluetooth may have 150–200ms, which is noticeable for lip-sync but acceptable for most video content.

Can I use the Relay for gaming or musical instruments?

No, due to Bluetooth transmission delay, it is not suitable for real-time applications like gaming, live monitoring, or instruments where precise timing is critical.

What should I do if my headphones automatically reconnect to another device?

Ensure Bluetooth is turned off on previously paired devices to prevent auto-connection issues; the Relay functions as a transmitter only and pairs exclusively with headphones.
