I have to strain to here anybody on my 3650 in all but the quietest of rooms. I even turned on the loudspeaker full volume and stuck it up to my ear just to hear the other person. Is this a unique experience, or does anybody else have this problem. My old 8260 was fine. I am not deaf, and strangley enough the earpiece seemed ok, though the volume was all the way up on that as well.
