Short answer: the Sony ULT Field 1 for better sound quality, the Ultimate Ears Wonderboom 2 for the lower price. The Sony ULT Field 1 ranks #76 of 136 medium speakers at $98. The Ultimate Ears Wonderboom 2 ranks #86 at $80, $18 cheaper.
What the Sony ULT Field 1 offers: IP67 rated, survives drops and 1m submersion. Real-world battery around 28+ hours with ULT (bass boost) mode off. Stereo-pairs with a second ULT Field 1. Watch for: Upper midrange peak, rolled off treble
What the Ultimate Ears Wonderboom 2 offers: IP67 rated and floats. Compact and light enough to toss in a bag. Watch for: Not stereo, barely any bass, recessed treble. Slightly boosted 93hz upper bass Dip at 9khz. 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 2019. Not technically a 360 speaker, only front and rear.
Buy the Sony ULT Field 1 if sound quality matters more than the price. Buy the Ultimate Ears Wonderboom 2 if the price matters more than sound quality.
