Short answer: the Ultimate Ears Wonderboom 3 on price and ruggedness, though neither ranks well in its class. It is IP67 rated, floats, survives a 5 ft drop onto hard surfaces and costs $113.01 less, though it is not stereo and has barely any bass. The Sony SRS-XB30 doubles as a power bank but sounds muffled, worse than an XB20. Both are rated below 3.0/5 among the 164 medium speakers; for better sound, the Earfun Uboom L ranks #2 at $49.79.
Buy the Ultimate Ears Wonderboom 3. It is rated higher for sound quality and still sold new, while the Sony SRS-XB30 is discontinued.
There is a real battery-life gap here: the Sony SRS-XB30 is rated for 24 hours, the Ultimate Ears Wonderboom 3 only 14 hours.

The Two Speakers In Full
Sony SRS-XB30: $199 Discontinued eBay
Newer model: the Sony ULT Field 3, ranked higher, rated 3.4/5.
Pros: A compact 1kg portable with IPX5 splash protection, aux input, LDAC/AAC support, Sony’s app, speakerphone capability, power-bank output, stereo pairing and Party Chain linking. It reaches a useful 95dB maximum level and has a claimed 24-hour battery life at moderate volume, making it a convenient older outdoor option. Measured bass extension of 55Hz (-10dB).
Cons: Independent lab listening rates music fidelity only fair: bass has impact but is boomy and lacks the deepest notes, while the midrange can sound hazy, muffled and grainy. Its micro-USB charging and older Bluetooth 4.2 platform now feel dated, so it is best considered for features and used-market value rather than sound quality. Discontinued.

Ultimate Ears Wonderboom 3: $85.99 Amazon eBay
Newer model: the Ultimate Ears Wonderboom 4, ranked higher, rated 2.9/5.
Pros: IP67 rated, floats, and is rated to survive a 5 ft drop onto hard surfaces. 14 hour battery: longer than the Wonderboom 2. Measured bass extension of 76Hz (-10dB).
Cons: Not stereo, barely any bass. Boosted 93Hz upper bass. Cuts bass heavily at high volume. You can tell from the micro USB that they are just feeding you the same crap hardware over and over, this is inexcusable for a product released in 2022. Not technically a 360 speaker, only front and rear.
