Quick fixes

Match what you see

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

⌁Earbuds won't join the transmitter
  1. Confirm the transmitter is powered on and playing TV audio.
  2. Place both earbuds in the charging case, close it for 5 seconds, then remove both together.
  3. Keep the earbuds close to the transmitter while they reconnect.

Expected: each earbud shows solid blue for 1 second, then its light turns off and TV sound plays. If not, submit a support ticket with the LED pattern.

🔇Joined, but no TV sound
  1. Check the cable: use TV audio OUT and connect it to transmitter OPTICAL or AUX.
  2. HDMI-only TV: connect HDMI ARC/eARC to HAX06, then HAX06 Optical OUT to transmitter OPT IN.
  3. Check the TV: Optical or HAX06 requires PCM/Stereo. AUX requires Headphones output and normal TV volume.
  4. Restart: turn the transmitter OFF, then ON.

Expected: the Audio Signal light is solid and dialogue plays. If it still blinks, recheck the selected TV output.

ARCTV only has HDMI ARC / eARC
  1. Aura Focus does not accept HDMI directly.
  2. Connect TV HDMI ARC/eARC to the HAX06 adapter.
  3. Connect HAX06 Optical OUT to transmitter Optical input.
  4. On the TV choose HDMI ARC/Receiver, turn eARC off if required, and select PCM/Stereo.

Expected: the Audio Signal light becomes solid. A standard HDMI cable connected directly to Aura Focus cannot work.

◉Charging-case middle light blinks, side lights stay solid
  1. Place both earbuds fully into the charging case and confirm their contacts are seated.
  2. Connect the case to USB-C power or place it correctly on the powered charging dock.
  3. Leave it charging for about 2 hours, then remove and reinsert both earbuds.

Expected: the three white case lights indicate the case battery level. If the middle light continues blinking abnormally after a full charge, submit a support ticket with a short video of the pattern.

±Volume taps respond slowly
  1. Tap the center of the round silver control once—left for volume down, right for volume up.
  2. Wait briefly for the volume step before tapping again.
  3. Dry the control surface and your fingertip, then retry.

Expected: each deliberate tap changes one volume step. If it remains unresponsive, use the transmitter + / − buttons and contact support.

⚡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.

🔋Earbuds 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 hours.

Share TV sound

Use TV speakers or a soundbar with Aura Focus

The TV must support two audio outputs at the same time.

TV SPEAKERS + EARBUDS

Possible when your TV supports simultaneous output

  1. Connect Aura Focus to the TV Optical output.
  2. In TV Sound settings, choose TV Speaker + Optical, Simultaneous Optical Output, or Dual Audio Output.
  3. Set Digital Audio Format to PCM.
SOUNDBAR + EARBUDS

First check whether the TV has a second active audio output

Yes — a separate Optical or AUX output works:
Keep the soundbar connected. Connect Aura Focus to that separate output, then enable simultaneous output on the TV.

No — HDMI ARC/eARC is the only active output:
Aura Focus and the soundbar cannot play together directly.

Important: Aura Focus has no audio passthrough. HAX06 can connect Aura Focus to an available HDMI ARC port, but it cannot split a port already used by a soundbar.

Private listening

Private Mode is coming soon

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

Until then

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