Short answer: the Onn Portable FM Boombox. It ranks #26 of 115 large speakers by sound quality, rated 4.2/5, at $74.83; the LG Xboom Bounce ranks #33, rated 4.0/5, and costs $103.17, which makes this an easy call rather than a real tradeoff.
Why pick the Onn Portable FM Boombox: An excellent value waterproof boombox that floats, with reasonably deep bass, FM radio, lights and a long battery. Watch for: Reasonable frequency response, but not quite as smooth as some of the top-ranked speakers in this size.
The LG Xboom Bounce is the longer-running, lighter pick. A tough, waterproof speaker that survives drops and extreme temperatures, with a long battery and multipoint pairing. It is rated for 30 hours of battery against 16 for the Onn Portable FM Boombox. At 2.9 lbs (1.32 kg) it weighs much less than the Onn Portable FM Boombox at 4.9 lbs (2.22 kg). It has an adjustable EQ, which the Onn Portable FM Boombox lacks. The tradeoff: Bass extension not as deep as the top speakers.
Buy the Onn Portable FM Boombox. It is rated higher for sound quality than the LG Xboom Bounce and costs less, so only choose the other one for a particular feature it does better.
