These sit in different size classes, so this is not a straight ranking comparison. The Soundcore Boom 3i ranks #31 of 179 medium speakers by sound quality at $118.99; the Bose Soundlink Micro ranks #20 of 62 small speakers by sound quality at $99.99.
The Soundcore Boom 3i is the deeper-bass, longer-running option. A warm, punchy waterproof speaker that sounds great and is a strong value. Its bass reaches about 56Hz before falling 10dB, against 66Hz for the Bose Soundlink Micro. It is rated for 16 hours of battery against 6 for the Bose Soundlink Micro. It supports AAC Bluetooth, which the Bose Soundlink Micro lacks. Watch for: 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 is the lighter pick. A rugged waterproof pocket speaker with a built in strap, party pairing, and low Bluetooth delay for video. At 0.6 lbs (289 g) it weighs much less than the Soundcore Boom 3i at 1.7 lbs (783 g). It links with other speakers (Bose Party mode), which the Soundcore Boom 3i cannot.
Buy the Soundcore Boom 3i ($118.99) for a medium speaker; the Bose Soundlink Micro ($99.99) suits a small speaker instead.
