Short answer: the Sony ULT Field 1 on measured sound quality, the Ultimate Ears Wonderboom on price. The Sony ULT Field 1 ranks #76 of 136 medium speakers at $98. The Ultimate Ears Wonderboom ranks #87 at $79, $19 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 offers: IP67 rated and floats. Compact, light, and simple to use. Watch for: Not stereo, barely any bass, recessed treble. Dip at 9khz. Low mid bass distortion. Not technically a 360 speaker, only front and rear.
Buy the Sony ULT Field 1 when sound quality outweighs the price for you, and the Ultimate Ears Wonderboom when the price outweighs sound quality instead.
