Short answer: the Tribit Stormbox Flow. It ranks #62 of 175 medium speakers by sound quality (rated 3.5/5) at $79.99 and is still sold new; the Sony SRS-XB20 ranks #120 (rated 2.8/5) and is discontinued, so it is only an option used. The Sony SRS-XB20’s replacement, the Sony ULT Field 1, is rated 3.1/5 at $138.
The Tribit Stormbox Flow is the better-sounding, longer-running pick. Up to 30 hours of battery life: roughly double most rivals (~20-24 hrs with XBass on). It is rated for 30 hours of battery against 12 for the Sony SRS-XB20. It is rated IPX7 against IPX5 for the Sony SRS-XB20. It has an adjustable EQ, which the Sony SRS-XB20 lacks. Watch for: Midrange and bass are weirdly recessed about 4db below 700Hz.
The case for the Sony SRS-XB20: It supports LDAC Bluetooth, which the Tribit Stormbox Flow lacks. It keeps a wired aux input, which the Tribit Stormbox Flow lacks. It plays in stereo from a single unit, unlike the Tribit Stormbox Flow. The catch: Sounds thin at higher volumes.
Buy the Tribit Stormbox Flow. It is rated higher for sound quality, and the Sony SRS-XB20 is discontinued, so it is only available used.

The Two Speakers In Full
Tribit Stormbox Flow: $79.99 Tribit $79.99 eBay
Same family: the Tribit Stormbox Micro 2 (smaller model, rated 4.5/5), the Tribit Stormbox Pro (larger model, ranked higher, rated 3.7/5) and the Tribit Stormbox Blast (larger model, rated 4.5/5). See every Tribit Stormbox generation.
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.
