Ensemble - Pair and Lock – Avantree Support

Ensemble headphones won't connect to the transmitter or keep disconnecting? Follow these steps to pair and lock the connection for automatic reconnection.

BEFORE YOU START

Your Ensemble headphones must connect to the Ensemble transmitter (base), NOT directly to your TV's Bluetooth.

Turn your TV OFF.
Turn Bluetooth OFF on nearby phones, tablets, computers, and other Bluetooth devices.
Keep the headphones close to the transmitter.

Pair the Headphones with the Transmitter

Put the Transmitter into Pairing Mode

Connect the transmitter to power and turn its side power switch ON.
Press and hold the Pair/Lock (↻) button for 5 seconds.

Flashing Red & Blue — Ready to pair.

Put the Headphones into Pairing Mode

Turn the headphones ON.
If the LED is not already flashing red and blue, hold the Play/Pause (▶⏸) button for 5 seconds.

Flashing Red & Blue — Ready to pair.

Wait for the Connection

Keep both devices close together until both LEDs turn solid blue.

Solid Blue — Successfully connected.

Lock the Connection

Connected? Now Lock It.

While both devices show solid blue, quickly double-click the Pair/Lock (↻) button on the transmitter.

This locks the headphones to the transmitter for automatic reconnection.

Test Automatic Reconnection

Turn the headphones OFF, then ON again. Wait for them to reconnect automatically.

Replacement Headphones Won't Connect?

Replacement headphones may need to be manually paired and locked with your existing transmitter.

Confirm the replacement headphones are compatible with Ensemble HT5150.
Turn OFF other headphones already connected to the transmitter.
Repeat Step 1: Pair and Step 2: Lock using the replacement headphones.
If pairing fails, reset the transmitter and replacement headphones, then try again.

Still won't connect?

Check the model and batch numbers of the transmitter and replacement headphones. Different production batches may require a compatibility check.

Transmitter Has No Light or Keeps Turning Off?

Make sure the transmitter's side power switch is ON.
Connect it to a working wall power adapter instead of a TV USB port.
Try another compatible USB power cable, adapter, or wall outlet.
Once the transmitter powers on normally, repeat Steps 1 and 2.

Still no light or repeatedly shutting off?

The transmitter may need further inspection. Contact Avantree Support with your batch number and the power checks you completed.

Still Need Help?

Include your Ensemble HT5150 batch number, whether you're using original or replacement headphones, the LED behavior, and a short video showing the issue.
