Listen with hearing aids

To join directly, your hearing-aid model must support Auracast. Bluetooth alone is not enough. Check your model and any receiver options in the guide below.

Before you start: Connect and power the transmitter, complete the TV sound settings in Step 3, and keep TV audio playing.

Check Hearing Aid mode

The transmitter LED beside Hearing Aids should be white.

Not white? Hold the transmitter’s Mode button for 3 seconds, then recheck.

Use the headphones with a Phone/PC

Connect the headphones directly—do not pair the transmitter.

Watch: connect to a phone or PC

Turn off the transmitter

This prevents the headphones from rejoining TV audio.

Start Bluetooth pairing

Hold the headphone switch at Pair with Phone for 3 seconds. Wait for red + blue flashing.

Select Aria Aura

Open Bluetooth on the phone or computer and select Aria Aura.

Confirm solid blue

A solid blue headphone LED means connected.

Back to TV: Turn off phone Bluetooth. Switch the headphones ON near the powered transmitter; wait for solid orange.

Charge the headphones

About 2.5 hours for a full charge.

Use the powered dock or USB-C with a 5 V, 1–2.4 A source.
On the dock, align the charging contacts.
Solid red means charging; the LED turns off when full.

Not charging?

If the battery is low, check the power source and reseat the headphones on the dock. Then try charging by USB-C. Solid red confirms charging. If neither method works, contact Support with the results of both tests.

Battery reference

Up to 35 hours of playtime. Actual time varies with volume, connection, and use.

Use a soundbar and headphones together

TV Optical audio enters the Opera Aura transmitter, passes from OPT OUT to a soundbar, and broadcasts wirelessly to the headphones — OPT IN → OPT OUT, or AUX IN → AUX OUT.

Update Opera Aura headphones

Download the Avantree Updater for your Windows PC or Mac.
Connect the Opera Aura headphones—not the transmitter dock—to your computer with a USB data cable.
Use the included gray-tip data cable. On Mac, an Apple charging cable also works.
Run the updater. Follow its instructions and keep the headphones connected until it says Complete.

After updating: follow the updater’s reset instructions.

Download Avantree Updater Notify me about updates

During the update: do not unplug the headphones, close the updater, or turn off the computer.

Cannot download or start the updater?

If the download fails or the headphones are not detected before an update starts, contact Support with your computer operating system and the error message.

Private Mode is coming soon

Private Mode uses an encrypted, password-protected Auracast broadcast.

What to expect

The feature is not available yet. Once released, it will be added to the headphones through a DFU firmware update.

See Firmware Update instructions ↑

Until then

Use the open Opera Aura broadcast for normal TV listening. The headphone app is only needed for password-protected broadcasts.
