The sound quality on this speaker is just bright, true, and I was able to hear all the ranges of songs I played on it. That bass boost is the bomb! People will probably just keep it on all the time, I think. I found this speaker to be really lovely, sound-wise, but personally, since I need a speaker to play to a larger audience (I'm a wedding minister) I was a bit disappointed in the max volume level. Sure, I know that really, really loud speakers are bad for you and so I'm not taking away any stars because if I want to speak to a large crowd, I need to get an actual PA system. I do have one but I'm always looking for something that can double as wedding music player and speaker system. Even though I wish the volume went higher on this, I am DEFINITELY not returning it because of the beyond excellent sound quality! I am truly impressed by this sound quality...I don't think that Bose could do much better. Truly.
