The boom sound feature also is a perk because it delivers loud volume quality sound

It mostly just bumps the volume and bass, and that really doesn't work for all kinds of music

And if you are using your car speakers to listen to music when a call comes through then all the people riding in your car will want to fight you if you don't somehow get the volume turned way down quickly before the other person hangs up because if you don't, then BEEP

The audio output is very good with my Klipsch S4i headphones, yet I still miss the volume control that works with other Android phones from Motorola and Samsung, and also my iPad
