Short answer: the Soundcore Boom Go 3i on measured sound quality, the JBL Go 4 on price. The Soundcore Boom Go 3i ranks #2 of 47 small speakers at $79.99. The JBL Go 4 ranks #25 at $49.95, $30.04 cheaper.
What the Soundcore Boom Go 3i offers: IP68 rated (full submersion + dustproof). ~24 hour battery life. RGB light strip syncs to the music. USB-C port doubles as a power bank for charging your phone. Watch for: Sounds a bit piercing and metallic. Bass knocks a little bit. Peak at 10khz
What the JBL Go 4 offers: A little more bass than the Go 3 and they fixed the strange mids peak. Watch for: Not much bass at all, especially with electronic/bass-heavy tracks pushed past ~50% volume. Midrange can sound grainy and treble a bit sizzly; loses clarity at higher volumes.
Buy the Soundcore Boom Go 3i if sound quality is the priority over the price, or the JBL Go 4 if the price is the priority over sound quality.
There is a real battery-life gap here: the Soundcore Boom Go 3i is rated for 24 hours, the JBL Go 4 only 7 hours.
