Short answer: the JBL Xtreme 3 if sound quality leads, the Onn Portable FM Boombox if you want to spend far less. The Xtreme 3 has better treble and deeper bass than the Xtreme 2 and is more balanced than the Xtreme 4. The onn counters with extreme value, IPX7 protection that lets it float, FM radio with 10 presets and six LED effects, but there is no custom EQ to close the bass gap.
Buy the JBL Xtreme 3 if sound quality matters more than the price. Buy the Onn Portable FM Boombox if the price matters more than sound quality.
