Short answer: both are discontinued, so this only matters if you are buying used. Used, the Soundcore Glow is the better pick: it ranks #47 of 157 medium speakers by sound quality (rated 3.6/5), against #57 (rated 3.5/5) for the JBL Charge 4. If you want one new, the Earfun Uboom L ranks #1 at $49.79.
Buy the Soundcore Glow only if you find one used in good condition; both are discontinued, and it is the better rated of the two. For a new speaker, start with the Earfun Uboom L instead.

The Two Speakers In Full
Soundcore Glow: $80 Discontinued eBay
Pros: Nice light show. Treble boosted 7db. Not technically a 360 speaker, only front and rear. Measured bass extension of 54Hz (-10dB).
Cons: Bass falls off quickly at louder volumes, leaving mostly treble; distortion on bass-heavy tracks at full volume. Light effects and bass-boost noticeably shorten battery life. USB-C port doesn’t support power-bank charging. Discontinued and no longer sold new.
