It has really great sound quality and loudness! I used it at work you don't even have to turn it up all the way to hear it through out the kitchen. it has great battery life also. it lasted a whole shift! Even at its loudest there's no distortion! I'll 100% recommend this speaker if you're looking for great sound and battery life!

Great speakers.

Love this speaker for the money you can't go wrong. Oh yeah you can get better but it's going to cost you a lot more money. Get two and pair them you will be happy you did.
