Sony SRS-XE300 vs Ultimate Ears Megaboom 4

Last updated: October 12, 2026

Short answer: the Sony ULT Field 3, if you are buying new, though neither ranks well in its class. The Sony SRS-XE300 ranks higher than the Ultimate Ears Megaboom 4 (#118 vs #170 of 175 medium speakers) but is discontinued; its replacement, the Sony ULT Field 3, is rated 3.4/5 at $208 and is still sold new. Both are rated below 3.0/5 among the 175 medium speakers, and the EarFun Uboom L, ranked #2 at $49.79, is a better place to start if sound quality matters.

Sony SRS-XE300 vs Ultimate Ears Megaboom 4

The Sony SRS-XE300 is the better-sounding choice. Orientation-aware playback switches to stereo when laid flat. It supports LDAC Bluetooth, which the Ultimate Ears Megaboom 4 lacks. It plays in stereo from a single unit, unlike the Ultimate Ears Megaboom 4. Watch for: Muffled sounding, not very deep bass.

The case for the Ultimate Ears Megaboom 4: IP67 rated, floats, and finally uses USB-C charging. The tradeoff: A lot of distortion at higher volumes.

Buy the Sony ULT Field 3, the replacement for the discontinued Sony SRS-XE300; it is rated higher for sound quality than the Ultimate Ears Megaboom 4.
