With Bluetooth speakers by Sony, you can enjoy powerful sound. The sleek boxes have multiple drivers and techniques that improve the sound quality. Choose a compact or medium size if you like to take the speaker with you. Almost all Bluetooth speakers by Sony are waterproof, but if you take the speaker to the beach or pool, check whether it has this feature. If you want to listen to your favorite songs all day long, go for a battery life of 12 hours or more.
