Short answer: the Tribit Stormbox Pro. It ranks #40 of 136 medium speakers by sound quality at $90; the Ultimate Ears Boom 4 ranks #88 and costs $105, so there is not much of a tradeoff to weigh.
What the Tribit Stormbox Pro offers: 24 hour battery life (60% volume, XBass off); doubles as a power bank. IP67 rated. Multi-point Bluetooth 5.3 pairing. Watch for: Bottom woofer was fixed in a later firmware, upgrade for best sound. Peaky mids, highs rolled off. Not technically a 360 speaker, only front and rear.
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%
Buy the Tribit Stormbox Pro. It ranks higher for sound quality than the Ultimate Ears Boom 4 and costs less, so there is no real case for the other one.
There is a real battery-life gap here: the Tribit Stormbox Pro is rated for 24 hours, the Ultimate Ears Boom 4 only 15 hours.
