The Two Speakers In Full
Earfun Uboom 360: $42 Discontinued eBay
Pros: Similar to the Maxsound Plus in sound, likely uses the same drivers. Likely the best 360 speaker. Measured bass extension of 61Hz (-10dB).
Cons: Not stereo. Slightly rolled off treble, not as deep of bass as the best in category. Outdoor mode is more flat, indoor mode boosts bass. Not technically a 360 speaker, only front and rear. Discontinued and no longer sold new. Discontinued.

Tribit Stormbox Micro: $40 Discontinued eBay
Pros: Quite neutral. Slight hollowness in the mids. Built in strap is super useful for attaching it to things. Highly recommend spending the extra $10 for the Micro 2 which goes louder and deeper. To have it aimed directly at you unclip the strap and the speaker will sit upright with a slight lean back. Measured bass extension of 62Hz (-10dB).
Cons: Gets murky and slightly sharp near max volume; boosted bass distorts when pushed loud. Down-firing passive radiator needs a flat surface underneath or the bass gets muffled. Discontinued and no longer sold new; superseded by the Stormbox Micro 2. Discontinued.
