Short answer: the Ultimate Ears Boom 3 on measured sound quality, the Xdobo X8 on price. The Ultimate Ears Boom 3 ranks #92 of 142 medium speakers at $149.99. The Xdobo X8 ranks #125 at $35, $114.99 cheaper.
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.
What the Ultimate Ears Boom 3 offers: Rich and warm bass without muddying mix, crisp highs, excellent 15-hour battery life, stable Bluetooth connectivity, IP67 rated and floats, rugged fabric shell, can pair up to 150 speakers via PartyUp Watch for: Not stereo, barely any bass, recessed treble. 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 2021. Lots of mentions of failing batteries on amazon. Not technically a 360 speaker, only front and rear.
Buy the Xdobo X8 if the price is the priority over sound quality, or the Ultimate Ears Boom 3 if sound quality is the priority over the price.
Skip the Xdobo X8 if sound quality matters to you. It ranks near the bottom of the 142 medium speakers.
