Short answer: the JBL Charge Essential 3 SE on measured sound quality, the Ultimate Ears Wonderboom 4 on price. The JBL Charge Essential 3 SE ranks #40 of 150 medium speakers, rated 3.7/5, at $199.95. The Ultimate Ears Wonderboom 4 ranks #95, rated 2.9/5, at $59.99, $139.96 cheaper.
What the JBL Charge Essential 3 SE does well: 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.
What the Ultimate Ears Wonderboom 4 does well: Small size. The tradeoff: Bass isn’t as deep as the top-ranked speakers and is a little thuddy.

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.
