Short answer: both are discontinued, so this only matters if you are buying used. Used, the JBL Flip 4 is the better pick: it ranks #82 of 164 medium speakers by sound quality (rated 3.3/5), against #101 (rated 3.0/5) for the Tribit Xsound Surf. If you want one new, the Earfun Uboom L ranks #2 at $49.79.
What the JBL Flip 4 gets right: Less bass than a Flip 5. The tradeoff: Battery failures are common.
Buy the JBL Flip 4 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.
