Short answer: the Ultimate Ears Boom 4 on measured sound quality, the Tribit Stormbox Mini on price. The Ultimate Ears Boom 4 ranks #88 of 136 medium speakers at $105. The Tribit Stormbox Mini ranks #116 at $23, $82 cheaper.
What the Ultimate Ears Boom 4 offers: IP67 rated, floats, and finally charges via USB-C instead of the older Booms’ Micro-USB. 15 hour battery. Customizable EQ and speaker-pairing via the UE app. Watch for: Not much improvement over the old ones. Weak bass extension and thuddy bass. Gets distorted above 90%
What the Tribit Stormbox Mini offers: IPX7 waterproof, excellent battery life (12 hours), RGB LED lighting, app support with AAC codec, true wireless stereo (TWS) capability, USB-C charging Watch for: Lacking quite a bit of bass. Sounds hollow and thuddy. Just not great overall.
Buy the Ultimate Ears Boom 4 when sound quality outweighs the price for you, and the Tribit Stormbox Mini when the price outweighs sound quality instead.
If sound quality matters at all to you, skip the Tribit Stormbox Mini. It ranks near the bottom of the 136 medium speakers, so look higher up the list instead.
