Short answer: the Ultimate Ears Wonderboom 2 for better sound quality, the Xdobo X8 for the lower price. The Ultimate Ears Wonderboom 2 ranks #89 of 142 medium speakers at $80. The Xdobo X8 ranks #125 at $35, $45 cheaper.
What the Ultimate Ears Wonderboom 2 offers: IP67 rated and floats. Compact and light enough to toss in a bag. Watch for: Not stereo, barely any bass, recessed treble. Slightly boosted 93hz upper bass Dip at 9khz. 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 2019. Not technically a 360 speaker, only front and rear.
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 Ultimate Ears Wonderboom 2 if sound quality is the priority over the price, or the Xdobo X8 if the price is the priority over sound quality.
If sound quality matters at all to you, skip the Xdobo X8. It ranks near the bottom of the 142 medium speakers, so look higher up the list instead.
