Short answer: the Tronsmart Force Max. It ranks #91 of 126 large speakers by sound quality, rated 3.0/5, at $119.99; the Ultimate Ears Epicboom ranks #95, rated 2.9/5, and costs $228.59, so there is little reason to consider the other one.
Why pick the Tronsmart Force Max: A waterproof party speaker that spreads sound in all directions, with power bank charging and plenty of playback options. It has an adjustable EQ, which the Ultimate Ears Epicboom lacks. The catch: Sonido Pesado found the Tronsmart Halo 100 clearly better, with clearer mids and highs.
The Ultimate Ears Epicboom is the longer-running, lighter option. A rugged, floating waterproof speaker made mostly from recycled materials, with long Bluetooth range and USB-C charging. It is rated for 17 hours of battery against 13 for the Tronsmart Force Max. At 4.3 lbs (1.97 kg) it weighs noticeably less than the Tronsmart Force Max at 5.6 lbs (2.54 kg). It plays in stereo from a single unit, unlike the Tronsmart Force Max. The tradeoff: Not very deep bass for the size.
Buy the Tronsmart Force Max. It is rated higher for sound quality than the Ultimate Ears Epicboom and costs less, so only choose the other one for a particular feature it does better.
