These sit in different size classes, so this is not a straight ranking comparison. The JBL Go 3 ranks #31 of 62 small speakers by sound quality at $35.95; the Soundcore 2 ranks #105 of 179 medium speakers by sound quality at $29.99.
The JBL Go 3 is the lighter pick. A pocket sized waterproof speaker with a rope loop for clipping to a bag. At 0.5 lbs (209 g) it weighs noticeably less than the Soundcore 2 at 0.7 lbs (318 g). It charges over USB-C rather than Micro USB. The tradeoff: Not much bass at all, strange mids peak.
The Soundcore 2 is the longer-running pick. A cheap, light waterproof stereo speaker with a long rated battery, an aux input and pairing with a second unit. It is rated for 24 hours of battery against 5 for the JBL Go 3. It keeps a wired aux input, which the JBL Go 3 lacks. It plays in stereo from a single unit, unlike the JBL Go 3. The tradeoff: Bass is specified only down to 70Hz, so the low end is limited.
Buy the JBL Go 3 at $35.95 for a small speaker, or the Soundcore 2 at $29.99 for a medium speaker instead.
