iPhone speaker sounds muffled during phone calls
A muffled speaker during calls is almost always dirt or lint blocking the speaker holes. Clean the bottom speaker grille with a dry soft brush. A dry toothbrush works perfectly. If that doesn't work, restart your iPhone and try a call to a friend to test it.
Your iPhone speaker has tiny holes that sound travels through. When lint, dust, or pocket debris builds up in those holes, the sound gets blocked and muffled. Cleaning the speaker grille is the quickest fix. If cleaning doesn't work, the problem is settings on your phone that need to be reset.

Skip — I just want a technicianCommon mistakes to avoid
- Trying to clean the speaker with a damp cloth. Water can damage the speaker, always use a dry brush
- Cleaning too hard or using sharp objects. You're just removing surface lint, not digging into the holes
- Not cleaning the microphone holes when the speaker is blocked. Both can cause muffled call audio
Signs you need professional help
- The speaker is still muffled after cleaning and restarting. The speaker now sounds completely quiet instead of muffled. You see water damage or the phone was dropped recently and now sounds muffled.
