Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The Soundcore Boom Go 3i ranks #2 of 62 small speakers by sound quality at $59.98; the JBL Flip 6 ranks #13 of 179 medium speakers by sound quality at $79.95.
The Soundcore Boom Go 3i is the longer-running, lighter pick. 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 12 for the JBL Flip 6. At 0.8 lbs (380 g) it weighs noticeably less than the JBL Flip 6 at 1.2 lbs (544 g). The tradeoff: 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.
The case for the JBL Flip 6: A small, rugged speaker with very neutral sound for its size, an excellent choice for most people. It supports AAC Bluetooth, which the Soundcore Boom Go 3i lacks. The catch: Some slight upper mids emphasis.
Buy the Soundcore Boom Go 3i at $59.98 for a small speaker, or the JBL Flip 6 at $79.95 for a medium speaker instead.
