I had a sprint TP2 for about a month. My girlfriend thought I was sad every time she talked to me. That was her interpratation of the muffled/far away sound.

I had to drop sprint because of coverage issues and went with the at&t tilt2. Sound quality is much crisper and brighter, I'm no longer sad according to the GF.

Not sure if it was coverage/signal issue or something specific to the Sprint model. Never could find anything on it and this is the first mention of it I've come across on any board.

Not very helpful but that's my experience with the problem you are having.

Edit: neudof has a point though, you might be having mic issues. Try holding the phone to your other ear and see if it makes a difference. Should flip the mic to the oppisite side which might help with voice and fingers.
