Short answer: the Xdobo X8. It ranks #125 of 142 medium speakers by sound quality at $35; the Ultimate Ears Megaboom 4 ranks #137 and costs $200, so there is little reason to consider the other one.
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
What the Xdobo X8 offers: A compact 860g speaker with a useful practical feature set: IPX5 splash resistance, USB-C charging, aux and microSD playback, speakerphone and TWS pairing. Reviews consistently find it surprisingly loud and full-bodied for the size, making it a plausible inexpensive outdoor/background-music option. Watch for: The single full-range driver is the limitation. Reviews note a harsh midrange, rolled-off treble and audible distortion, while bass extension is only about 65Hz. It can play loud, but it does not have the clarity or control for attentive listening.
Buy the Xdobo X8. It ranks higher for sound quality than the Ultimate Ears Megaboom 4 and costs less, so there is no real case for the other one.
If sound quality matters at all to you, skip both of these and look higher up the 142 medium speakers instead.
