4. Bypass Function for Soundbar/AVR
The innovative bypass feature allows the headphones to work simultaneously with your existing soundbar or stereo AV Receiver, sharing the same audio output port on your TV. This means you can hear the TV at your own volume through the headphones while others hear directly through the sound system.
- Connect your TV's audio output to the "INPUT FROM TV" port on the transmitter (e.g., Optical).
- Connect the "OUTPUT TO SPEAKER" port on the transmitter (e.g., Optical) to your soundbar or AV Receiver's audio input.

Troubleshooting
If you encounter any issues with your SIMOLIO SM-829D2 headphones, please refer to the following common solutions or contact support.
No Sound Issues
One of the most common issues is no sound from the headphones. This is often related to TV audio settings. Ensure your TV's digital audio output is set to PCM (Pulse-Code Modulation) format, especially when using optical connection.
- Check TV Sound Output Settings: Navigate to your TV's sound settings and ensure the audio output is directed to the correct external device (Optical/Headset/External Speaker) and not just the TV speakers.
- Set Digital Output to PCM: For optical connections, verify that your TV's Digital Sound Output Format is set to PCM. Dolby Digital or other surround sound formats may not be compatible.
- Power Cycle TV: Unplug your TV from the power outlet for a few minutes, then plug it back in. This can resolve temporary audio glitches.
