UE MEGABOOM Portable Bluetooth Speaker (1-Piece): Bring any party to the next level with a portable speaker that offers 360° sound, dynamic wireless control from up to 2 Bluetooth-enabled devices at once, and a lightweight, waterproof design. Download the app to unlock cool, new features like a musical alarm, custom-tuning options and more.
If you want a tough and easily portable bluetooth speaker that has solid sound quality, give the UE MEGABOOM a try. It puts out a lot of sound for its size and has good battery life. I think it sounds the best when you put it up high in the corner of a room. So far I have been a fan of UE's products and the MEGABOOM is no exception.
