Sound Weak, Muffled or Distorted: Causes & Fixes
Work through these in order
- Blocked wax guard or dome — Change wax guard + dome first — resolves ~60% of cases.
- Moisture in the receiver — Full night in the drying kit; humidity-season staple.
- Hearing change since last programming — If cleaning doesn't restore clarity, book a free retest; aids are reprogrammed to your new audiogram at no charge in the first year.
- Microphone ports clogged with dust — Brush mic ports gently, openings facing down.
