These sit in different size classes, so this is not a straight ranking comparison. The JBL Go 3 ranks #26 of 47 small speakers by sound quality at $39.95; the Ultimate Ears Wonderboom 4 ranks #89 of 144 medium speakers by sound quality at $59.99.
Why pick the JBL Go 3: Genuinely pocket-sized at 209g. The catch: Not much bass at all, strange mids peak.
The case for the Ultimate Ears Wonderboom 4: Small size. The tradeoff: Bass isn’t as deep as the top-ranked speakers and is a little thuddy.
Buy the JBL Go 3 at $39.95 if you want a small speaker. Buy the Ultimate Ears Wonderboom 4 at $59.99 if you want a medium speaker instead.
Battery life favors the Ultimate Ears Wonderboom 4: rated for 14 hours against 5 hours for the JBL Go 3.
