All I can say is WOW. It is super loud and vibrant compaired to my Hero. And I thought that the speaker on that was decent. All my music actually sounds good (great hi's and mid's, obviously not much lows but come on) coming out of it with tons of volume. It's great to fall asleep with as a clock radio if you will. This phone is IMO better than what I was expecting, and this one feature is one that truly suprised me.
