These are not really the same size class, and that is the honest framing here. The JBL Go 4 ranks #30 of 62 small speakers by sound quality at $49.95; the Xdobo X8 ranks #160 of 179 medium speakers by sound quality at $35.
The JBL Go 4 is the lighter, tougher pick. A pocket sized waterproof mini speaker with a loop for hanging and app EQ. At 0.4 lbs (190 g) it weighs much less than the Xdobo X8 at 1.9 lbs (860 g). It is rated IP67 against IPX5 for the Xdobo X8. The tradeoff: Not much bass at all, especially with electronic/bass-heavy tracks pushed past ~50% volume.
The Xdobo X8 is the deeper-bass, longer-running option. A cheap splash resistant speaker that plays loud for background music outdoors, with aux and microSD playback. Its bass reaches about 65Hz before falling 10dB, against 82Hz for the JBL Go 4. It is rated for 15 hours of battery against 7 for the JBL Go 4. It keeps a wired aux input, which the JBL Go 4 lacks. The tradeoff: The single full-range driver is the limitation.
Worth knowing: the Xdobo X8 has been discontinued and is hard to find new at this point.
Buy the JBL Go 4 ($49.95) for a small speaker; the Xdobo X8 ($35) suits a medium speaker instead.
