Short answer: the JBL Charge 6 for better sound quality, the Ultimate Ears Boom 4 for the lower price. The JBL Charge 6 ranks #11 of 136 medium speakers at $199.95. The Ultimate Ears Boom 4 ranks #88 at $105, $94.95 cheaper.
What the JBL Charge 6 gets right: 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. The tradeoff: Still some boosted bass by default. Mids are recessed. Bright above 2khz.
What the Ultimate Ears Boom 4 offers: IP67 rated, floats, and finally charges via USB-C instead of the older Booms’ Micro-USB. Set against that: Not much improvement over the old ones. Weak bass extension and thuddy bass.
Buy the JBL Charge 6 if sound quality matters more than the price. Buy the Ultimate Ears Boom 4 if the price matters more than sound quality.
If battery life is a priority, the JBL Charge 6 is rated for 24 hours versus 15 hours for the Ultimate Ears Boom 4.

JBL Charge 6: $199.95 Amazon Bhphotovideo eBay
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
Cons: Still some boosted bass by default. Mids are recessed. Bright above 2khz. Quite a V shaped frequency response.
