Short answer: both are discontinued, so this only matters if you are buying used. Used, the Bogasing M4 is the better pick: it ranks #28 of 164 medium speakers by sound quality (rated 4.0/5), against #87 (rated 3.2/5) for the JBL Flip Essential. If you want one new, the Earfun Uboom L ranks #2 at $49.79.
The Bogasing M4 is the better-sounding, longer-running choice. Super Bass mode gives the most balanced sound. It is rated for 24 hours of battery against 10 for the JBL Flip Essential. It plays in stereo from a single unit, unlike the JBL Flip Essential. It charges over USB-C rather than Micro USB. The tradeoff: It sounds a bit harsh and thin.
The JBL Flip Essential is the lighter option. A genuinely portable 1 lbs (471 g) speaker with IPX7 water resistance, a 3.5mm aux input and 16W output from two full-range drivers. At 1 lbs (471 g) it weighs noticeably less than the Bogasing M4 at 1.6 lbs (731 g). The catch: Bass is lighter than the Flip 5 and the 80Hz claimed low-frequency limit means it cannot deliver real low-end weight.
Buy the Bogasing M4 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
Bogasing M4: $45.99 Discontinued eBay
Newer model: the Bogasing M5, ranked lower, rated 3.5/5.

Super Bass mode gives the most balanced sound. Measured bass extension of 54Hz (-10dB).
Cons: Bass is limited by its 54Hz specification. There is no companion app. No EQ adjustment. It sounds a bit harsh and thin. Discontinued.

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.
