Short answer: the JBL Charge 6 for a more neutral balance, the Earfun Uboom Slim on price. The Slim offers IPX7 waterproofing, 16 hours of battery, smooth sound with volume compensation and speakerphone capability, but its bass is not as deep as others and it is warm tuned with peaks in the mids and lower treble. The Charge 6 costs $70.95 more and is more neutral than the Charge 5, though it still boosts bass by default.
Buy the JBL Charge 6. It is rated higher for sound quality, and the $70.95 saving on the Earfun Uboom Slim is not enough to make up the difference.
Battery life favors the JBL Charge 6: rated for 24 hours against 16 hours for the Earfun Uboom Slim.

JBL Charge 6: $149.95 Amazon B&H Photo Video eBay
Older models: the JBL Charge 5 (ranked lower, rated 4/5), the JBL Charge 4 (ranked lower, rated 3.5/5), the JBL Charge 3 (ranked lower, rated 3.2/5) and the JBL Charge 2 (ranked lower, rated 3.2/5).
Pros: Seems more neutral than the Charge 5. Flatter frequency response through the mids and treble as the Charge 5 was quite rolled off up high. Use this EQ from Joy/Oluv and turn down the lowest bass slider for the best sound quality. Oluv has even more paid EQs specifically for the GG and TL models indoors and outdoors here. IP68 protection, a 7-band app EQ, Auracast, USB-C charging and a power bank output. Measured bass extension of 53Hz (-10dB).
Cons: Still some boosted bass by default. Mids are recessed. Bright above 2kHz. Quite a V shaped frequency response.
