Short answer: the Sony ULT Field 1. It ranks #99 of 177 medium speakers by sound quality (rated 3.1/5) at $108 and is still sold new; the Xdobo X8 ranks #158 (rated 2.3/5) and is discontinued, so it is only an option used.
The Sony ULT Field 1 is the better-sounding, lighter pick. A tough, waterproof small speaker that survives drops, with long real world battery life and stereo pairing. At 1.4 lbs (650 g) it weighs noticeably less than the Xdobo X8 at 1.9 lbs (860 g). It is rated IP67 against IPX5 for the Xdobo X8. The tradeoff: Upper midrange peak, rolled off treble.
Why pick the Xdobo X8: A cheap splash resistant speaker that plays loud for background music outdoors, with aux and microSD playback. It keeps a wired aux input, which the Sony ULT Field 1 lacks. The tradeoff: The single full-range driver is the limitation.
Buy the Sony ULT Field 1. It is rated higher for sound quality and still sold new, while the Xdobo X8 is discontinued.
