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 Klipsch Detroit ranks #76, rated 3.1/5, and costs $235.11, which makes this an easy call rather than a real tradeoff.
The Onn Portable FM Boombox is the better-sounding option. An excellent value waterproof boombox that floats, with reasonably deep bass, FM radio, lights and a long battery. The catch: Reasonable frequency response, but not quite as smooth as some of the top-ranked speakers in this size.
Why pick the Klipsch Detroit: A rugged, fully waterproof stereo boombox with a long battery, fast USB-C charging, and power bank output. The catch: Weird boosted upper bass, bass not very deep.
Buy the Onn Portable FM Boombox. It is rated higher for sound quality than the Klipsch Detroit and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
