Quick Answer
If you hear crackling, popping, or unusually high-pitched audio while using HellBlocker, cycle HellBlocker on and off before testing playback again. This can refresh the noise-cancellation system if it has temporarily fallen out of sync.
Symptoms
Follow these steps if:
- Audio crackles or pops.
- Voices or music sound unusually high-pitched.
- The sound changes unexpectedly when using HellBlocker.
How to Refresh HellBlocker
- Play audio where you can clearly hear the issue.
- Turn HellBlocker off.
- Turn HellBlocker back on.
- Turn HellBlocker off again.
- Continue playing the audio and check whether the sound has returned to normal.
Result: The crackling, popping, or high-pitched audio should stop if HellBlocker was temporarily out of sync.
If the Issue Continues
- Test the same audio with HellBlocker off.
- Note whether the issue occurs in the left, right, or both earbuds.
- Test another song or audio source.
- Try another app and connected device.
- Check the HEAVYS App for available firmware updates.
