Great speaker. The bass button doesn't make a huge difference but the bass on this thing is insane. High quality sound and really loud. I would say that battery isn't the best out there because I had the UEboom and I never had to charge that thing but this Sony looks better and is better quality.

Great sound to this speaker. Very pleased with it. Would definitely recommend.

Very good ...good sound quality as compared to size

I have used it constantly in my truck for about nine months. A super product for the price. However, I always have USB cord plugged in, so I don't know how long battery will last without a charge.

I have about 11 different Bluetooth speakers fugoo, Anker Altec Lansing, Bose, and many more brands. Sony blows them all away, will buy more Bluetooth waterproof speakers from Sony I guarantee that Buy these SPEAKERS you will not be disappointed trust me on that one

Works fantastic. I use it at hand at church when either I sing or the youth group sings. Bought refurbished and then ordered another to give to my teenage son.
