People have no problem hearing me. Hearing them, on the other hand, is a total challenge on the 650, even more than it was on the 600. Then try to listen to another person in big city traffic... will never happen. Very frustrating. Palm should get rid of that stupid "fancy" earpiece design and make something more acoustically sound and also allow us to boost the volume. I don't supposed the voice app above does anything for raising the sound quality or levels to your ear, does it?
