    Awesome speaker. Looks good and sounds great. Bass is slightly lacking but I knew that going in. It's high quality and feels that way. Perfect for outdoors and around kids, especially if a pool is involved and it's water resistant.

    It sounds good, not audiophile quality. When volume gets to max it makes an annoying beep sound and stops music, which is an awful feature.
