These are not really the same size class, and that is the honest framing here. The Soundcore 3 ranks #62 of 157 medium speakers by sound quality at $59.99; the JBL Go 3 ranks #28 of 50 small speakers by sound quality at $39.95.
The Soundcore 3 is the louder, deeper-bass option. Identical in acoustic design and performance to the retailer variant Soundcore Select 2. Its bass reaches about 60Hz before falling 10dB, against 87Hz for the JBL Go 3. Alan Ross Reviews measured it at 99dB at full volume, against 88dB for the JBL Go 3. It is rated for 24 hours of battery against 5 for the JBL Go 3.
The JBL Go 3 is the lighter pick. Genuinely pocket-sized at 0.5 lbs (209 g). At 0.5 lbs (209 g) it weighs much less than the Soundcore 3 at 0.8 lbs (372 g). Watch for: Not much bass at all, strange mids peak.
Buy the Soundcore 3 at $59.99 for a medium speaker, or the JBL Go 3 at $39.95 for a small speaker instead.
