Short answer: the JBL Flip Essential 2, if you are buying new. The Bogasing M4 ranks higher than it (#28 vs #81 of 164 medium speakers, 4.0/5 vs 3.3/5) but is discontinued, so only consider it used; the JBL Flip Essential 2 is still sold new at $85.90.
The Bogasing M4 is the better-sounding, longer-running option. Super Bass mode gives the most balanced sound. It is rated for 24 hours of battery against 10 for the JBL Flip Essential 2. It keeps a wired aux input, which the JBL Flip Essential 2 lacks. It plays in stereo from a single unit, unlike the JBL Flip Essential 2. Watch for: It sounds a bit harsh and thin.
The JBL Flip Essential 2 is the lighter choice. Essentially a Flip 5 in a new shell: the same single 44 x 80mm racetrack driver and 20W amplifier, rated down to 65Hz. At 1.1 lbs (520 g) it weighs noticeably less than the Bogasing M4 at 1.6 lbs (731 g). The catch: There is no tweeter, and side by side comparisons found it does not sound as good as the Flip 6, with less bass; its bass stops growing above about 70% volume, so turning it up mostly adds loudness, not weight.
Buy the JBL Flip Essential 2 new; the Bogasing M4 is no longer sold new, so it only makes sense as a used find.

JBL Flip Essential 2: $85.90 Amazon eBay
Older model: the JBL Flip Essential (ranked lower, rated 3.2/5).
Pros: Essentially a Flip 5 in a new shell: the same single 44 x 80mm racetrack driver and 20W amplifier, rated down to 65Hz. In a side by side loudness test it got louder than the JBL Grip, and listeners comparing it with the Marshall Emberton found it more open sounding and clearer. IPX7 waterproof, 520 g, USB-C charging and Bluetooth 5.1 with two phones connected at once.
Cons: There is no tweeter, and side by side comparisons found it does not sound as good as the Flip 6, with less bass; its bass stops growing above about 70% volume, so turning it up mostly adds loudness, not weight. No app, no EQ, no PartyBoost or stereo pairing, a claimed 10 hours of battery, and IPX7 covers water but not dust.
