Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The Soundcore Boom 3i ranks #31 of 179 medium speakers by sound quality at $118.99; the Bose Soundlink Micro 2 ranks #18 of 62 small speakers by sound quality at $129.

The Soundcore Boom 3i is the longer-running option. A warm, punchy waterproof speaker that sounds great and is a strong value. It is rated for 16 hours of battery against 12 for the Bose Soundlink Micro 2. 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 Bose Soundlink Micro 2 is the lighter pick. A waterproof mini speaker with a fabric strap for bags and bikes and USB-C charging. At 0.7 lbs (329 g) it weighs much less than the Soundcore Boom 3i at 1.7 lbs (783 g). It supports aptX Bluetooth, which the Soundcore Boom 3i lacks. It links with other speakers (Bose Party mode), which the Soundcore Boom 3i cannot. The catch: Lack of clarity.
Buy the Soundcore Boom 3i at $118.99 for a medium speaker, or the Bose Soundlink Micro 2 at $129 for a small speaker instead.
