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 Grip ranks #98 of 179 medium speakers by sound quality at $69.95.
The Soundcore Boom Go 3i is the longer-running 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 14 for the JBL Grip. 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 Grip: A small, fully waterproof speaker with app EQ, ambient lighting, Auracast linking and USB-C audio input. The tradeoff: Lacking deeper bass, definitely the worst of the JBL line until you get to the smaller clip.
Buy the Soundcore Boom Go 3i at $59.98 for a small speaker, or the JBL Grip at $69.95 for a medium speaker instead.
