These are not really the same size class, and that is the honest framing here. The Earfun Uboom 360 ranks #30 of 134 medium speakers at $42; the Tribit Stormbox Micro ranks #5 of 46 small speakers at $40.
The case for the Earfun Uboom 360: Similar to the Maxsound Plus in sound, likely uses the same drivers. The tradeoff: Not stereo.
What the Tribit Stormbox Micro gets right: Quite neutral. The catch: Gets murky and slightly sharp near max volume.
Buy the Earfun Uboom 360 at $42 if you want a medium speaker. Buy the Tribit Stormbox Micro at $40 if you want a small speaker instead.

The Two Speakers In Full
Earfun Uboom 360: $42 Amazon
Pros: Similar to the Maxsound Plus in sound, likely uses the same drivers. Likely the best 360 speaker.
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.

Tribit Stormbox Micro: $40 Amazon
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.
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.
