While this isn’t a common issue, there are a few things that can occasionally cause high-pitched sounds, buzzing, or reduced volume, especially if it’s only happening in one earbud.
What might be causing it?
- Pressure on the speaker driver: If abnormal pressure is applied to the earbud, such as pressing it too firmly into the ear, using an incorrect fit, or something pressing against it, this can sometimes trigger feedback or a high-pitched tone.
- Blocked speaker mesh: A buildup of earwax or debris on the speaker mesh can also lead to sound issues, including lower volume or high-pitched noise. This can happen gradually over time and may not always be visible to the eye.
What can I do to fix it?
Please try the following steps:
- Clean the speaker grille:
Gently brush the speaker mesh on each earbud using a clean, soft, dry toothbrush.
For a deeper clean, you can lightly dampen the brush with a small amount of isopropyl alcohol (surgical spirit). Just be careful not to let any liquid get inside the earbud. - Try different eartips:
A poor seal can affect both sound quality and clarity. Testing different tip sizes might resolve the issue. - Pair with another device:
This helps determine whether the issue is with the earbuds or the connected device.
