Short answer: the Ultimate Ears Wonderboom 4, though neither ranks well in its class. It ranks #89 of 144 medium speakers by sound quality, rated 2.9/5, at $59.99. The Ortizan X10 ranks #128, rated 2.2/5, at $39.99, $20 cheaper, which does not close the gap in sound quality. Both are rated below 3.0/5 among the 144 medium speakers, so if sound quality matters, consider the Earfun Uboom L instead, ranked #1 at $49.79.
Why pick the Ultimate Ears Wonderboom 4: Small size. The tradeoff: Bass isn’t as deep as the top-ranked speakers and is a little thuddy.
What the Ortizan X10 does well: IPX7 rated and pairs with a second X10 for stereo (TWS). The tradeoff: Not much bass, very rolled off treble.
Buy the Ultimate Ears Wonderboom 4. It is rated higher for sound quality, and saving $20 with the Ortizan X10 does not make up for the sound-quality gap.
There is a real battery-life gap here: the Ortizan X10 is rated for 30 hours, the Ultimate Ears Wonderboom 4 only 14 hours.
