iPhone: Sound muffled or low from the speaker or when speaking into the mic
Symptoms
When I play music or listen to a call through the speaker phone, the sound may appear low or muffled, or the person I'm talking to claims that I sound muffled or not loud enough.

Resolution
Check the following
- Check the volume setting on your iPhone. You can adjust the volume by pressing the volume up and down buttons on the left side of the iPhone.
- If you are using a third-party iPhone case, make sure it is not covering the speaker or microphone. Try making some calls without the case to see if a caller can now hear you more clearly or play music to see if the speaker's volume is better.
- If you have not removed the plastic display film used for protection during shipment, either ensure that the microphone and speaker are not covered or remove the film completely.
- Check that the holes in the speaker and mic cover are not clogged with lint or other debris.
- If the speaker and mic holes appear clogged, please use a clean, small, dry, soft-bristled brush to clean out the holes. To do this follow these instructions:
- Use the brush to carefully and gently brush the speaker and mic holes.
- Brush away from the 30-pin dock connector to avoid getting any debris into the dock connector.
