- No Sound: Ensure the plug is fully inserted into the device's audio port. Check your device's volume settings and ensure the earbuds are selected as the output device.
- Distorted Sound: Try reducing the volume on your device. Ensure the cable is not damaged or kinked. For Type-C versions, check the Nordi APP settings if applicable.
