I recently received an email from a reader who wrote:
“I’m having issues with my ReSound Vivia hearing aids. I notice static, intermittency, and sometimes a clicking sound. Has anyone else had this problem, and what should I do?”
These symptoms are fairly common, and one of the most frequent causes is a clogged microphone cover.
Why the Microphone Cover Matters
ReSound hearing aids have tiny protective covers over the microphones. Over time, these covers can become blocked with dust, moisture, or debris. When that happens, you may hear static, distorted sound, or clicking noises.
The good news? This is often an easy fix at home by simply replacing the mic covers. This is similar to other regular maintenance tasks like changing hearing aid tubing, domes, and wax traps.
How to Change a ReSound Microphone Cover
Replacing the microphone cover only takes a few minutes.
- Use the removal tool provided with the replacement kit to lift out the old microphone cover.
- Align the new cover with the microphone opening.
- Press gently until it clicks securely into place.
- Test your hearing aids to confirm improved sound quality.
If your device still has intermittent sound, you may also want to review my guide on hearing aids cutting in and out.

Final Audiologist Tip
If changing the microphone covers doesn’t solve the problem, the next step is to see your audiologist. In many cases, they will run a test and may need to replace the receiver if that’s the source of the issue.
