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 Sony ULT Field 1 ranks #81 of 144 medium speakers by sound quality at $98.
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 Sony ULT Field 1: IP67 rated, survives drops and 1m submersion. The tradeoff: Upper midrange peak, rolled off treble.
Buy the JBL Go 3 at $39.95 if you want a small speaker. Buy the Sony ULT Field 1 at $98 if you want a medium speaker instead.
There is a real battery-life gap here: the Sony ULT Field 1 is rated for 12 hours, the JBL Go 3 only 5 hours.
