Troubleshooting
- No Audio/Poor Connection:
- Ensure the headset is charged and powered on.
- Verify the Loop 100 USB Dongle is securely plugged into your computer and its indicator light is solid blue.
- If using direct Bluetooth, ensure the headset is in pairing mode and selected on your device.
- Check the Bluetooth range (up to 10 meters). Move closer to your device.
- Microphone Issues:
- Ensure the boom microphone is flipped down and positioned correctly near your mouth.
- Check your device's audio settings to ensure the OpenComm UC is selected as the input device.
- The active noise cancellation on the microphone is designed to reduce background noise, but extremely loud environments may still affect clarity.
- Sound Quality/Bone Conduction:
- Bone conduction audio is experienced differently than traditional in-ear or over-ear headphones. Sound is transmitted through your cheekbones.
- Ensure the transducers are placed firmly on your cheekbones for optimal sound.
- If experiencing muted sound, adjust the position of the transducers slightly.
