Short answer: the Soundcore Motion X600 if sound quality matters most, the Onn Portable FM Boombox if price matters most. The Soundcore Motion X600 ranks #19 of 115 large speakers, rated 4.3/5, at $159.99. The Onn Portable FM Boombox ranks #26, rated 4.2/5, at $74.83, $85.16 cheaper.
The case for the Soundcore Motion X600: A stereo speaker with impressive sound after its latest firmware update, especially with a well tuned EQ. The tradeoff: Stock frequency response is wavy.
The Onn Portable FM Boombox is the longer-running option. An excellent value waterproof boombox that floats, with reasonably deep bass, FM radio, lights and a long battery. It is rated for 16 hours of battery against 12 for the Soundcore Motion X600. The catch: Reasonable frequency response, but not quite as smooth as some of the top-ranked speakers in this size.
Buy the Soundcore Motion X600 if sound quality is the priority over the price, or the Onn Portable FM Boombox if the price is the priority over sound quality.
