Short answer: both are discontinued, so this only matters if you are buying used. Used, the Soundcore Boost “upgraded” 2021 is the better pick: it ranks #5 of 175 medium speakers by sound quality (rated 4.4/5), against #118 (rated 2.8/5) for the Sony SRS-XE300. If you want one new, the Sony ULT Field 3 replaces the Sony SRS-XE300 and is rated 3.4/5 at $208.
The Soundcore Boost “upgraded” 2021 is the better-sounding, lighter pick. A very neutral good sounding inexpensive small speaker with quite deep bass for the size. At 1.3 lbs (590 g) it weighs much less than the Sony SRS-XE300 at 2.9 lbs (1.3 kg). Watch for: Slight DSP tuning issue which makes bass get lighter at times at very low volumes, examples in oluv’s video.
The Sony SRS-XE300 is the longer-running option. Orientation-aware playback switches to stereo when laid flat. It is rated for 24 hours of battery against 12 for the Soundcore Boost “upgraded” 2021. It supports LDAC Bluetooth, which the Soundcore Boost “upgraded” 2021 lacks. It links with other speakers (Party Connect up to 100 speakers), which the Soundcore Boost “upgraded” 2021 cannot. Watch for: Muffled sounding, not very deep bass.
Buy the Soundcore Boost “upgraded” 2021 only if you find one used in good condition; both are discontinued, and it is the better rated of the two. For a new speaker, buy the Sony ULT Field 3, which replaces the Sony SRS-XE300.
