Short answer: the Ultimate Ears Wonderboom 4, though neither ranks well in its class. It ranks #109 of 179 medium speakers by sound quality, rated 2.9/5, at $64.99. The Ortizan X10 ranks #162, rated 2.2/5, at $29.97, $35.02 cheaper, which does not close the gap in sound quality. Both are rated below 3.0/5 among the 179 medium speakers, so if sound quality matters, consider the EarFun Uboom L instead, ranked #2 at $49.79.
The Ultimate Ears Wonderboom 4 is the better-sounding, lighter choice. A small, tough waterproof speaker with a strap loop and USB-C charging, easy to clip on a bag for outdoor trips. At 0.9 lbs (420 g) it weighs noticeably less than the Ortizan X10 at 1.3 lbs (590 g). It charges over USB-C rather than Micro USB. The catch: Bass isn’t as deep as the top-ranked speakers and is a little thuddy.
The Ortizan X10 is the longer-running choice. A cheap waterproof speaker with colorful LED lighting, a long rated battery and stereo pairing. It is rated for 30 hours of battery against 14 for the Ultimate Ears Wonderboom 4. It keeps a wired aux input, which the Ultimate Ears Wonderboom 4 lacks. It has an adjustable EQ, which the Ultimate Ears Wonderboom 4 lacks. The catch: Not much bass, very rolled off treble.
Buy the Ultimate Ears Wonderboom 4. It is rated higher for sound quality, and saving $35.02 with the Ortizan X10 does not make up for the sound-quality gap.
