Short answer: the Ultimate Ears Wonderboom 4 on price, the JBL Flip Essential only for aux in. The Wonderboom 4 costs $78.95, $51.05 less and ranks #106 of 164, but its bass is not as deep as the top-ranked speakers and sounds a little thuddy. The Flip Essential has the wired input and less bass than a Flip 5.
Buy the Ultimate Ears Wonderboom 4 new; the JBL Flip Essential is no longer sold new, so it only makes sense as a used find.

The Two Speakers In Full
JBL Flip Essential: $130 Discontinued eBay
Newer model: the JBL Flip Essential 2, ranked higher, rated 3.3/5.
Pros: A genuinely portable 471g speaker with IPX7 water resistance, a 3.5mm aux input and 16W output from two full-range drivers. It is a simple, no-app option for wired sources, travel and casual listening where its cylindrical shape and modest size are a genuine advantage.
Cons: Bass is lighter than the Flip 5 and the 80Hz claimed low-frequency limit means it cannot deliver real low-end weight. Battery life is only a claimed 10 hours, there is no speakerphone, EQ or party mode, and its older Bluetooth 4.1 platform and discontinued status make it a basic used-market choice.
