Short answer: the Sony SRS-XE300. It ranks #92 of 136 medium speakers by sound quality at $137; the Ultimate Ears Megaboom 4 ranks #132 and costs $200, so there is little reason to consider the other one.
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
What the Ultimate Ears Megaboom 4 offers: IP67 rated, floats, and finally uses USB-C charging. 20 hour battery life. ‘PartyUp’ feature syncs multiple UE speakers together. Watch for: A lot of distortion at higher volumes. Rolled off treble. Not very loud. They really screwed this up
Buy the Sony SRS-XE300. It ranks higher for sound quality than the Ultimate Ears Megaboom 4 and costs less, so the other one has nothing left to offer.
If sound quality matters at all to you, skip the Ultimate Ears Megaboom 4. It ranks near the bottom of the 136 medium speakers, so look higher up the list instead.
