Short answer: the Ultimate Ears Megaboom 3 if sound quality matters most, the Sony SRS-XE300 if price matters most. The Ultimate Ears Megaboom 3 ranks #83 of 136 medium speakers at $163. The Sony SRS-XE300 ranks #92 at $137, $26 cheaper.
What the Ultimate Ears Megaboom 3 offers: IP67 rated, floats, and survives drops from up to 1 meter. 20 hour battery life - about double most speakers this size. Watch for: Not stereo, barely any bass. 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 2018. Not technically a 360 speaker, only front and rear.
What the Sony SRS-XE300 offers: IP67 rated. Orientation-aware playback switches to stereo when laid flat. Party Connect links up to 100 speakers; fast charging (10 min charge = ~70 min playback). Watch for: Muffled sounding, not very deep bass. Hollow sounding. Worse than a XB43
Buy the Ultimate Ears Megaboom 3 if sound quality matters more than the price. Buy the Sony SRS-XE300 if the price matters more than sound quality.
