Short answer: the Ultimate Ears Boom 4 on measured sound quality, the Ortizan X10 on price, though neither ranks well in its class. The Ultimate Ears Boom 4 ranks #99 of 150 medium speakers, rated 2.9/5, at $109.99. The Ortizan X10 ranks #134, rated 2.2/5, at $29.97, $80.02 cheaper. Both are rated below 3.0/5 among the 150 medium speakers, and the Earfun Uboom L, ranked #1 at $49.79, is a better place to start if sound quality matters.
The case for the Ultimate Ears Boom 4: IP67 rated, floats, and finally charges via USB-C instead of the older Booms’ Micro-USB. The tradeoff: Not much improvement over the old ones.
The case for the Ortizan X10: IPX7 rated and pairs with a second X10 for stereo (TWS). Watch for: Not much bass, very rolled off treble.
Buy the Ultimate Ears Boom 4 if sound quality is the priority over the price, or the Ortizan X10 if the price is the priority over sound quality.
