Short answer: the Sony ULT Field 1 on measured sound quality, the Xdobo X8 on price. The Sony ULT Field 1 ranks #79 of 142 medium speakers at $98. The Xdobo X8 ranks #125 at $35, $63 cheaper.
What the Sony ULT Field 1 offers: IP67 rated, survives drops and 1m submersion. Real-world battery around 28+ hours with ULT (bass boost) mode off. Stereo-pairs with a second ULT Field 1. Watch for: Upper midrange peak, rolled off treble
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 Sony ULT Field 1 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.
