Short answer: the Ultimate Ears Wonderboom 4, though neither ranks well in its class. It ranks #109 of 175 medium speakers by sound quality (rated 2.9/5) at $74.50 and is still sold new; the Sony SRS-XE300 ranks #118 (rated 2.8/5) and is discontinued, so it is only an option used. The Sony SRS-XE300’s replacement, the Sony ULT Field 3, is rated 3.4/5 at $208. 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 Wonderboom 4 is the lighter option. At 0.9 lbs (420 g) it weighs much less than the Sony SRS-XE300 at 2.9 lbs (1.3 kg). Watch for: Bass isn’t as deep as the top-ranked speakers and is a little thuddy.
The Sony SRS-XE300 is the longer-running pick. Orientation-aware playback switches to stereo when laid flat. It is rated for 24 hours of battery against 14 for the Ultimate Ears Wonderboom 4. It supports LDAC Bluetooth, which the Ultimate Ears Wonderboom 4 lacks. It links with other speakers (Party Connect up to 100 speakers), which the Ultimate Ears Wonderboom 4 cannot. Watch for: Muffled sounding, not very deep bass.
Buy the Ultimate Ears Wonderboom 4. It is rated higher for sound quality; the Sony SRS-XE300 is no longer sold new.
