Short answer: the Soundcore Boom 3i. It ranks #31 of 182 medium speakers by sound quality, rated 4.0/5, at $118.99. The DOSS Soundbox Pro ranks #174, rated 2.1/5, at $29.99, $89 cheaper, not enough of a saving to outweigh the sound-quality gap.
The Soundcore Boom 3i is the better-sounding, tougher choice. A warm, punchy waterproof speaker that sounds great and is a strong value. It is rated IP68 against IPX6 for the DOSS Soundbox Pro. It charges over USB-C rather than Micro USB. The tradeoff: Not quite as good as a JBL Charge 5, doesn’t go quite as loud or sound quite as balanced, but very very close.
The DOSS Soundbox Pro is the lighter pick. An inexpensive water resistant stereo speaker with an extra bass button, LED lights, a long rated battery and an aux input. At 1.2 lbs (558 g) it weighs noticeably less than the Soundcore Boom 3i at 1.7 lbs (783 g). It keeps a wired aux input, which the Soundcore Boom 3i lacks. It plays in stereo from a single unit, unlike the Soundcore Boom 3i. The catch: Barely any bass.
Buy the Soundcore Boom 3i. It is rated higher for sound quality, and saving $89 with the DOSS Soundbox Pro does not make up for the sound-quality gap.
