Start setup

Set up the Opera Aura kit.

This is the best choice for most users: lower delay and louder sound.

Want to connect without the transmitter? — more audio delay and no Volume Boost.

Quick fixes

Match what you see.

Each fix states the action, expected result, and next step.

⌁Headphones won't join the transmitter
  1. Confirm the transmitter is on and playing TV audio.
  2. Keep the headphones close to the transmitter and at least 2 m from Wi-Fi routers or microwaves.
  3. Double-press ⏯ if the LED is red + blue, then hold ⏯ for 3 seconds until it flashes orange.
  4. Wait for solid orange.

Expected: solid orange and TV sound. If it still fails, hold + and − together for 5 seconds to reset the headphones, then search again.

🔇Joined, but no TV sound
  1. Check the cable: use a TV audio OUT port and match the transmitter selector to HDMI ARC, OPT, or AUX.
  2. Check the transmitter: a solid Audio Signal light means usable TV audio is arriving. If it blinks, correct the cable or TV settings first.
  3. Check the TV: for Optical/HDMI ARC choose the matching Sound Output and set Digital Audio Format to PCM; for HDMI ARC also turn eARC off.
  4. Check volume: raise the TV volume for AUX, then raise the headphone volume and try Voice Clear 1 or 2.
  5. Restart: turn the transmitter OFF, then ON.

Expected: the Audio Signal light is solid and spoken dialogue plays. Still silent? Reopen Step 2 and follow the matching connection path from the beginning.

ARCHDMI ARC has no sound
  1. Use the TV port labeled HDMI ARC/eARC—not a standard HDMI input.
  2. Select HDMI ARC/Receiver as TV Sound Output.
  3. Turn eARC off and set Digital Audio Format to PCM.
  4. Set the transmitter Input Selector to HDMI ARC, then restart the TV and transmitter.

A soundbar already using the ARC port must be disconnected or rerouted; Opera Aura soundbar pass-through is Optical/AUX only.

⚡No light on transmitter
  1. Reconnect USB-C at both ends.
  2. Try a known-working 5 V USB adapter.
  3. Slide the transmitter switch to OFF, then ON.

If there is still no light, submit a support ticket with a photo of the power connection.

🔋Headphones will not charge
  1. Confirm the dock has power.
  2. Align the charging contacts and look for solid red.
  3. Try USB-C charging directly.
  4. Allow about 2.5 hours.

Make dialogue louder

Adjust volume in this order.

Start with the source, then fine-tune the headphones.

1. TV and transmitter

  • TV/source volume: raise it first when using AUX.
  • Volume Boost: switch it ON at the transmitter for +6 dB. It supports AUX, Optical, and HDMI ARC.

2. Headphones

  • Volume: raise it slowly to a comfortable level.
  • Voice Clear: headphones ship in Balance mode. Try Voice Clear 1, then Voice Clear 2 for the strongest dialogue emphasis.

Bluetooth · Phone / PC

Use the headphones with a Phone/PC.

Connect the headphones directly—do not pair the transmitter.

1

This prevents the headphones from rejoining TV audio.

2

Start Bluetooth pairing

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

3

Select Aria Aura

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

4

Return to TV listening Turn off the phone's Bluetooth, then switch the headphones to ON near the powered transmitter. Wait for solid orange.

Daily use

Charge the headphones.

Use the powered dock or a USB-C cable.

Power & charging

About 2.5 hours for a full charge.

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

Not charging? Reseat the headphones or USB-C cable and verify the power source.

Battery reference
