I find Sony's speaker in general, reliable and balanced. This one is no exception and mind you, you can put this speaker at full blast and never get any "artifacts" like other speakers where they begin to sound crappy at full volume.

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

Bluetooth speakers come in all shapes and colors. Some are large, designed to fill an entire room with sound for your next party. Others are portable, designed to be carried with you wherever you go.

I am really enjoying this product. The Bluetooth feature is really easy to use, the sound is great, and it is visually impressive.

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
