These sit in different size classes, so this is not a straight ranking comparison. The Soundcore Boom Go 3i ranks #2 of 62 small speakers by sound quality at $59.98; the Soundcore Boom 3i ranks #31 of 179 medium speakers by sound quality at $118.99.
The Soundcore Boom Go 3i is the longer-running, lighter choice. A tough, floating mini speaker with full waterproofing, a long battery and a detachable strap, built for travel and the outdoors. It is rated for 24 hours of battery against 16 for the Soundcore Boom 3i. At 0.8 lbs (380 g) it weighs much less than the Soundcore Boom 3i at 1.7 lbs (783 g). It links with other speakers (Auracast), which the Soundcore Boom 3i cannot. The catch: This is still a 15W mono speaker: bass impact and stereo width are limited, and critical listeners may find the upper treble piercing or metallic.
Why pick the Soundcore Boom 3i: A warm, punchy waterproof speaker that sounds great and is a strong value. It supports AAC Bluetooth, which the Soundcore Boom Go 3i 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.
Buy the Soundcore Boom Go 3i ($59.98) for a small speaker; the Soundcore Boom 3i ($118.99) suits a medium speaker instead.
