FAQ
Can I use the Avantree Relay with my smartphone?
No, the Relay is designed as a transmitter for airplane seat audio jacks and similar sources, not for connecting to phones or tablets to avoid compatibility issues.
How do I connect two headphones at the same time?
Simply pair the first headphone by holding the adapter’s button until it flashes, then repeat for the second headphone; both will stream audio simultaneously from the source.
Is there any audio delay when watching movies?
Delay depends on your headphones; aptX Adaptive models offer low latency for near-perfect sync, while standard Bluetooth may have 150-200ms delay, which could be noticeable for lip-syncing.
What should I do if my headphones don’t connect automatically?
Ensure Bluetooth is turned off on previously paired devices to prevent auto-connection conflicts, and reset the adapter by holding the button for 10 seconds if needed.
Can I use this for gaming or musical instruments?
No, the Relay is not suitable for real-time applications due to Bluetooth latency, which affects rhythm-critical uses like gaming or instrument monitoring.
