Short answer: the JBL Charge Essential 3 SE on measured sound quality, the Tribit Stormbox Flow on price. The JBL Charge Essential 3 SE ranks #40 of 150 medium speakers, rated 3.7/5, at $199.95. The Tribit Stormbox Flow ranks #55, rated 3.5/5, at $79.99, $119.96 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.
Why pick the Tribit Stormbox Flow: Up to 30 hours of battery life: roughly double most rivals (~20-24 hrs with XBass on). The catch: Not stereo.
Buy the JBL Charge Essential 3 SE when sound quality outweighs the price for you, and the Tribit Stormbox Flow when the price outweighs sound quality instead.

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.

Tribit Stormbox Flow: $79.99 Tribit eBay
Pros: Up to 30 hours of battery life: roughly double most rivals (~20-24 hrs with XBass on). IP67 rated with a loose handle for carrying/hanging. Pairs with a second Flow for stereo; USB-C port charges your phone too. Measured bass extension of 47Hz (-10dB).
Cons: Not stereo. Midrange and bass are weirdly recessed about 4db below 700Hz. You need xbass mode for it to not sound like a clock radio with missing bass. You also can’t turn up the bass enough in the custom EQ modes to get it neutral, so it will sound bass light. Firmware 1.2.3 fixes the distortion issues with xbass mode on, but bass still sounds wobbly and uncontrolled.
