What the Tribit Stormbox Micro 3 does well: Tribit Stormbox Micro 3 uses 48mm NdFeB driver with coaxial passive radiators. The tradeoff: Bass is limited by its 62Hz specification.
Why pick the Ultimate Ears Boom 4: IP67 rated, floats, and finally charges via USB-C instead of the older Booms’ Micro-USB. Watch for: Not much improvement over the old ones.
Buy the Tribit Stormbox Micro 3 at $59.99 for a small speaker, or the Ultimate Ears Boom 4 at $119.99 for a medium speaker instead.
