These sit in different size classes, so this is not a straight ranking comparison. The Soundcore Boom 3i ranks #29 of 144 medium speakers by sound quality at $118.99; the Bose Soundlink Micro ranks #19 of 47 small speakers by sound quality at $83.99.
The case for the Soundcore Boom 3i: Looks to be designed as a direct competitor to the Charge 5 with a very similar sound profile, warm tuned with boosted bass. Watch for: Not quite as good as a Charge 5, doesn’t go quite as loud or sound quite as balanced, but very very close.
The case for the Bose Soundlink Micro: Bose Soundlink Micro uses 40mm with dual passive radiators. Watch for: Bass is limited by its 66Hz specification.
Buy the Soundcore Boom 3i ($118.99) for a medium speaker; the Bose Soundlink Micro ($83.99) suits a small speaker instead.
If battery life is a priority, the Soundcore Boom 3i is rated for 16 hours versus 6 hours for the Bose Soundlink Micro.
