Short answer: the Soundcore Mini 3 Pro. It ranks #8 of 47 small speakers by sound quality at $30; the JBL Go 4 ranks #25 and costs $49.95, so there is little reason to consider the other one.
What the Soundcore Mini 3 Pro offers: Lights on top. Deeper bass than most other speakers in the size. Watch for: Rolled off highs. Real-world battery life falls well short of the 15-hour claim at higher volumes. Buttons are hard to see (black print on black housing) and it won’t multipoint to two phones at once.
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 Mini 3 Pro. It ranks higher for sound quality than the JBL Go 4 and costs less, so there is no real case for the other one.
Battery life favors the Soundcore Mini 3 Pro: rated for 15 hours against 7 hours for the JBL Go 4.
