Short answer: the Sonos Move 2. It ranks #28 of 115 large speakers by sound quality, rated 4.1/5, at $480. The Ultimate Ears Epicboom ranks #84, rated 2.9/5, at $228.59, $251.41 cheaper, which does not close the gap in sound quality.
The Sonos Move 2 is the better-sounding, longer-running pick. A Wi-Fi and Bluetooth portable with warm, full sound, clear mids and a long battery for moving around the home. It is rated for 24 hours of battery against 17 for the Ultimate Ears Epicboom. The catch: Not very loud.
The Ultimate Ears Epicboom is the lighter option. A rugged, floating waterproof speaker made mostly from recycled materials, with long Bluetooth range and USB-C charging. At 4.3 lbs (1.97 kg) it weighs noticeably less than the Sonos Move 2 at 6.6 lbs (3 kg). The tradeoff: Not very deep bass for the size.
Buy the Sonos Move 2. It is rated higher for sound quality, and the $251.41 saving on the Ultimate Ears Epicboom is not enough to make up the difference.
