Short answer: the Ultimate Ears Wonderboom 4. It ranks #84 of 136 medium speakers by sound quality at $59.99; the Sony SRS-XE300 ranks #92 and costs $137, so there is little reason to consider the other one.
What the Ultimate Ears Wonderboom 4 offers: Small size. Watch for: Bass isn’t as deep as the top-ranked speakers and is a little thuddy. Not much improvement over the previous Ultimate Ears Wonderboom 3 besides the USB-C charging port.
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 Wonderboom 4. It ranks higher for sound quality than the Sony SRS-XE300 and costs less, so there is no real case for the other one.
There is a real battery-life gap here: the Sony SRS-XE300 is rated for 24 hours, the Ultimate Ears Wonderboom 4 only 14 hours.
