Short answer: the Megaboom 3 takes drops and floats; the Charge 3 carries the power bank. The Megaboom 3 is IP67 rated, floats, and survives drops from up to 1 meter, but it is not stereo and has barely any bass. The Charge 3 doubles as a 6000mAh power bank for USB devices, though it has less clarity than the Flip 4.
Buy the Ultimate Ears Megaboom 3 if you want one new; the JBL Charge 3 is discontinued, so only look for it used.

Ultimate Ears Megaboom 3: $111.63 Amazon eBay
Newer model: the Ultimate Ears Megaboom 4, ranked lower, rated 2.1/5.
Pros: IP67 rated, floats, and survives drops from up to 1 meter. 20 hour battery life: about double most speakers this size. Measured bass extension of 70Hz (-10dB).
Cons: Not stereo, barely any bass. You can tell from the micro USB that they are just feeding you the same crap hardware over and over, this is inexcusable for a product released in 2018. Not technically a 360 speaker, only front and rear.
