    Stereo sound in portable devices. These speakers deliver excellent base and are rugged and portable. Download the UE Boom app to control from your phone. I tested these at the store and they were superior to Bose & JBL.

    We really like this speaker....its not small but not big....great sound considering the size ....the large volume buttons are kinda funky (retro looking) which we liked. Great purchase all around and would buy it again.

    I read many positive reviews regarding these speakers so I decided to go with them because I liked how waterproof and though they are. After using these for a couple of weeks I noticed right away and ongoing that there is consistent skipping in the playback. I did some reading about turning off the voice over function to solve this issue but it did not work. Another issue was big volume control delay via Bluetooth. Positives are the ability to pair speakers for stereo sound, waterproof and drop resistant as well as the 360 degree sound. I just can’t look past the lagging volume control and consistent dropping of sound on playback. I will be returning these.
