HT5009 Plus - How To Reconnect and Lock – Avantree Support

Your HT5009 Plus headphones may not reconnect automatically because the saved Bluetooth connection was lost, interrupted, or not properly locked.

Make sure the transmitter and headphones are both ON.
Keep the headphones close to the transmitter.
