Cases and mic quality in speakerphone

[Arelunde]

Has anyone noticed a connection between having a case on or off and the quality of mic on a speakerphone call?

I'm getting comments that I'm muffled from time to time during a speakerphone call. I took off my case and the listener said my voice was clear. Put the case back on, muffled again.

Tried it with a TPU case, Seidio and the Vz case that comes with a holster. Same results for all, even though the Vz case is minimal and has a large cutout area around the back speaker.

None of my cases cramp the mic area on the front. If that little hole below the speaker is also a mic, it always is clear, but some of the cases only have a small hole around it.

I use an Otterbox Commuter & have never had anyone say I sounded muffled.

No issues here with VZW Superior Dual cover and the thin cheap ones from VZW.

No issues here either. Use the Leather case from VZW and the Holster Combo.
