Short answer: the Ultimate Ears Boom 4, though neither ranks well in its class. It ranks #113 of 175 medium speakers by sound quality, rated 2.9/5, at $129.99. The Sony SRS-XE200 ranks #143, rated 2.5/5, at $99.99, $30 cheaper, which does not close the gap in sound quality. Both are rated below 3.0/5 among the 175 medium speakers, so if sound quality matters, consider the EarFun Uboom L instead, ranked #2 at $49.79.
The Ultimate Ears Boom 4 is the better-sounding, lighter pick. IP67 rated, floats, and finally charges via USB-C instead of the older Booms’ Micro-USB. At 1.4 lbs (620 g) it weighs noticeably less than the Sony SRS-XE200 at 1.8 lbs (800 g). The tradeoff: Not much improvement over the old ones.
What the Sony SRS-XE200 does well: IP67 rated with dedicated per-function buttons. It supports LDAC Bluetooth, which the Ultimate Ears Boom 4 lacks. The tradeoff: Sounds hollow.
Buy the Ultimate Ears Boom 4. It is rated higher for sound quality, and the $30 saving on the Sony SRS-XE200 is not enough to make up the difference.
Still deciding? The full Portable Bluetooth rankings cover every ranked option.

Sony SRS-XE200: $99.99 Amazon $99.99 eBay
