Short answer: the Soundcore Boom 2 if sound quality matters most, the onn Portable FM Boombox if price matters most. The Soundcore Boom 2 ranks #10 of 78 large speakers at $89.99. The onn Portable FM Boombox ranks #23 at $74.83, $15.16 cheaper.
What the Soundcore Boom 2 offers: Pretty deep bass for the size. Cool lights in the side passive radiators. For the best sound quality use Oluv’s EQ or Alan Ross’s EQ. With the stock tuning, this speaker would rank around #24, due to the boosted bass and rising treble. Watch for: Only a single midrange driver, so you only get stereo for the tweeters. Sound processing issues with inconsistent bass notes that disappear at low levels like the Soundcore Boom and Soundcore Boost, not great for listening at low levels. Quite bass heavy with BassUp turned on, I’d recommend turning it off. A little bit of a bright tuning in the treble, about +5db.
What the onn Portable FM Boombox offers: Extremely good value. Reasonably deep bass, though not as deep as something like the JBL Xtreme 3, Soundcore Boom 2, or Tribit Stormbox Lava. IPX7 waterproof and floats. FM radio with 10 presets. 6 multicolor LED lighting effects. Can run on battery or corded power. Watch for: Reasonable frequency response, but not quite as smooth as some of the top-ranked speakers in this size. No custom EQ. Only available in the United States and Canada.
