Who I have the same questioned this topic

Got my new D2G a few days ago and absolutely love it.  But, there's a problem that has got me frustrated to no end.  I can receive and make calls, but I cannot hear the person on the other end of the call.  They can hear me loud and clear, but they sound like they're a million miles away ... the sound is very faint.

This is  unacceptable.  I've tried everything I know but cannot figure out what's wrong. 

Any ideas?
