What the Ultimate Ears Boom 4 offers: IP67 rated, floats, and finally charges via USB-C instead of the older Booms’ Micro-USB. 15 hour battery. Customizable EQ and speaker-pairing via the UE app. Watch for: Not much improvement over the old ones. Weak bass extension and thuddy bass. Gets distorted above 90%
What the Sony SRS-XE200 offers: IP67 rated with dedicated per-function buttons. Can prop up a phone/tablet as a stand. Fast charging (10 min charge = ~70 min playback); Stamina mode extends battery when low. Watch for: Sounds hollow. Very muffled. Rolled off treble, weird midrange boost, just not great overall. Worse than a XB33.
Buy the Ultimate Ears Boom 4 if sound quality matters more than the price. Buy the Sony SRS-XE200 if the price matters more than sound quality.
