Short answer: the Soundcore Boom 3i. It ranks #31 of 177 medium speakers by sound quality (rated 4.0/5) at $118.99 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 Soundcore Boom 3i is the better-sounding, deeper-bass choice. A warm, punchy waterproof speaker that sounds great and is a strong value. Its bass reaches about 56Hz before falling 10dB, against 65Hz for the Xdobo X8. It is rated IP68 against IPX5 for the Xdobo X8. The catch: Not quite as good as a JBL Charge 5, doesn’t go quite as loud or sound quite as balanced, but very very close.
The case for 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 Soundcore Boom 3i lacks. The catch: The single full-range driver is the limitation.
Buy the Soundcore Boom 3i. It is rated higher for sound quality and still sold new, while the Xdobo X8 is discontinued.
