Short answer: the Ultimate Ears Wonderboom 4 if sound quality matters most, the Xdobo X8 if price matters most. The Ultimate Ears Wonderboom 4 ranks #87 of 142 medium speakers at $59.99. The Xdobo X8 ranks #125 at $35, $24.99 cheaper.
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 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 4 if sound quality is the priority over the price, or the Xdobo X8 if the price is the priority over sound quality.
The Xdobo X8 is not a sound-quality pick. It sits near the bottom of the 142 medium speakers; there are better options higher up.
