These are not really the same size class, and that is the honest framing here. The JBL Go 4 ranks #30 of 62 small speakers by sound quality at $49.95; the Soundcore 2 ranks #105 of 179 medium speakers by sound quality at $29.99.
The JBL Go 4 is the lighter pick. A pocket sized waterproof mini speaker with a loop for hanging and app EQ. At 0.4 lbs (190 g) it weighs much less than the Soundcore 2 at 0.7 lbs (318 g). It has an adjustable EQ, which the Soundcore 2 lacks. It charges over USB-C rather than Micro USB. The tradeoff: Not much bass at all, especially with electronic/bass-heavy tracks pushed past ~50% volume.
The Soundcore 2 is the longer-running choice. 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 7 for the JBL Go 4. It keeps a wired aux input, which the JBL Go 4 lacks. It plays in stereo from a single unit, unlike the JBL Go 4. The catch: Bass is specified only down to 70Hz, so the low end is limited.
Buy the JBL Go 4 at $49.95 if you want a small speaker. Buy the Soundcore 2 at $29.99 if you want a medium speaker instead.
