Short answer: the Soundcore Mini 3 ranks #9 of 47 small speakers by sound quality at $41; the JBL Go 3 ranks #26 at $39.95. Close enough in price that the sound-quality gap is the deciding factor.
What the Soundcore Mini 3 offers: Deeper bass than most other speakers in the size. Watch for: Rolled off highs
What the JBL Go 3 offers: Genuinely pocket-sized at 209g. IP67 rated, survives full submersion in a meter of water for 30 minutes. Rope loop for clipping to a bag. Watch for: Not much bass at all, strange mids peak.
