Your hearing aids are meant to work together and give you balanced, natural sound. When one side sounds quieter, muffled or distorted, it is a sign that something needs attention. At Hear SF on Geary Boulevard in San Francisco, owner and hearing aid dispenser Michael Martinez, NB-HIS, and our team can check both devices and your hearing to find the cause.
Common Reasons One Hearing Aid Sounds Different
- Clogged wax guard: Earwax is the most common reason one side suddenly sounds weak.
- Blocked dome, earmold or tubing: Wax or moisture can build up and muffle sound.
- Low battery or charging issue: One device may not be charging fully or may have a weak battery.
- Settings out of sync: Volume, programs or phone connections can change on one side.
- Changes in fit: A loose or shifted fit can affect sound and cause whistling.
- Earwax in your ear: Buildup in the ear canal itself can block sound.
- A change in your hearing: Sometimes the device is fine and your hearing in one ear has changed.
Quick Checks You Can Try at Home
Replace the wax guard, clean the dome or earmold, and make sure the device is fully charged or has a fresh battery. Restart both hearing aids and check that they are on the same program and volume in your app.
When to Visit Your Hearing Care Provider
If the difference continues after these steps, book a visit. Your hearing aids may need repair or reprogramming. If the hearing in one ear drops suddenly, contact a physician right away, because sudden hearing loss is treated as urgent.
