When the battery gets down to 70% ( and that doesn’t take long) the volume drops about 80% !,!
And so you plug the charger in and while charging the volume still is very low. So you only get 30% battery time at normal usage.
Not happy

Pretty good speaker for the money. Good sound and great lights. Just dont put it near the shower as steam will cause the sound to distort, it will dry out and go back to normal

Crystal clear sound, easy to set up, light and portable. The light display is simple, but great for going to sleep with. The sony app doesn't work with iPhone 4, but can still play music etc on speaker.
