When you purchase through links in our articles, we may earn a small commission. The Wonderboom 4 floats, survives submersion up to 1 meter, and lasts 14 hours on a full charge. It's now $52 (was $100) at Amazon. Specially designed to float, you can take it with you to the pool/beach and actually bring it into the water with you. The sound quality is fine, and fine is good enough because you aren't buying a speaker like this for top-notch sound.
