Short answer: the Charge Essential for the power bank, the Boom 4 for water handling. The Boom 4 is IP67 rated, floats and finally charges via USB-C instead of Micro-USB, but it is not much of an improvement over the older Booms. The Charge Essential doubles as a power bank, though it has less clarity than a Flip 4 with rolled-off highs.
Buy the JBL Charge Essential. It is rated higher for sound quality than the Ultimate Ears Boom 4 and costs less, so only choose the other one for a particular feature it does better.
