Short answer: the JBL Charge Essential 3 SE. It ranks #40 of 150 medium speakers by sound quality, rated 3.7/5, at $199.95. The Ultimate Ears Boom 4 ranks #99, rated 2.9/5, at $109.99, $89.96 cheaper, which does not close the gap in sound quality.
Why pick the JBL Charge Essential 3 SE: Gets louder than the Bose SoundLink Flex 2nd Gen and digs deeper in the bass, with a separate 20mm tweeter, two passive radiators and 40W of amplification in the familiar Charge body. Watch for: In side-by-side listening against the Charge 6, its bass is weaker and less stable and distorts on bass-heavy tracks even with the bass turned down in the app, while a narrow boost in the upper mids makes it sound less natural.
Why pick the Ultimate Ears Boom 4: IP67 rated, floats, and finally charges via USB-C instead of the older Booms’ Micro-USB. Watch for: Not much improvement over the old ones.
Buy the JBL Charge Essential 3 SE. It is rated higher for sound quality, and saving $89.96 with the Ultimate Ears Boom 4 does not make up for the sound-quality gap.

The Two Speakers In Full
JBL Charge Essential 3 SE: $199.95 JBL eBay
Older models: the JBL Charge Essential 2 (ranked higher, rated 3.8/5) and the JBL Charge Essential (ranked lower, rated 3.2/5).
Pros: Gets louder than the Bose SoundLink Flex 2nd Gen and digs deeper in the bass, with a separate 20mm tweeter, two passive radiators and 40W of amplification in the familiar Charge body. IP67 water and dust protection, a claimed 20 hours of battery life, a USB-C power bank output, Auracast stereo pairing and multi-speaker linking, Bluetooth 5.4 with AAC, and app EQ.
Cons: In side-by-side listening against the Charge 6, its bass is weaker and less stable and distorts on bass-heavy tracks even with the bass turned down in the app, while a narrow boost in the upper mids makes it sound less natural. Against the Bose SoundLink Flex 2nd Gen it sounds muddier and more strident, with less detail and a smaller soundstage. At full price it costs as much as the Charge 6, which is the better speaker.
