HT5009 Reset Pairing Issues – Avantree Support

Reset both the transmitter and headphones to clear their Bluetooth pairing history, then turn them back on to reconnect.

Important — Before You Reset

Turn Bluetooth OFF on nearby phones, tablets, computers, and other Bluetooth devices before starting. This prevents the HT5009 from connecting to another device during the reset.

Reset Both Devices

The HT5009 transmitter and headphones are factory paired and locked together. Resetting clears other pairing history, but the original set remains paired and locked.

Watch for the Pink Light

Keep holding until the red and blue LEDs are both on for about 2 seconds. Together, they may look pink. This means the headphone pairing history has been cleared.

Turn the Headphones Off

Once you see the red and blue pairing light, turn the headphones OFF.

Turn Both Devices Back On
