onn Portable FM Boombox: $74.83 Walmart eBay
Pros: 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.
Cons: 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.
