Ultimate Ears Wonderboom 2 vs Sony SRS-XE300

Last updated: October 1, 2026

Short answer: the Ultimate Ears Wonderboom 2 on price, the Sony SRS-XE300 for stereo when flat, though neither ranks well in its class. The XE300 is IP67 rated and its orientation-aware playback switches to stereo when laid flat, but it sounds muffled, has not very deep bass and is called worse than a XB43. The Wonderboom 2 is IP67 rated and floats, though it is not stereo and has barely any bass and recessed treble. Both are rated below 3.0/5 among the 157 medium speakers, so if sound quality matters, consider the Earfun Uboom L instead, ranked #1 at $49.79.

Ultimate Ears Wonderboom 2 ranking card

Newer model: the Ultimate Ears Wonderboom 4, ranked higher, rated 2.9/5.

Pros: IP67 rated and floats. Compact and light enough to toss in a bag. Measured bass extension of 82Hz (-10dB).

Cons: Not stereo, barely any bass, recessed treble. Slightly boosted 93Hz upper bass Dip at 9kHz. You can tell from the micro USB that they are just feeding you the same crap hardware over and over, this is inexcusable for a product released in 2019. Not technically a 360 speaker, only front and rear.
