Short answer: the KEF Muo gen2 if sound quality matters most, the Sony SRS-XE300 if price matters most. The KEF Muo gen2 ranks #73 of 136 medium speakers at $249.99. The Sony SRS-XE300 ranks #92 at $137, $112.99 cheaper.
What the KEF Muo gen2 offers: KEF seemed to have fixed the rolled off treble and overall balance Watch for: Lacking deeper bass. Very thuddy bass. Appears to be the exact same hardware but with updated tuning. Bass distorts as volume increases, and the claimed 43Hz extension is really only audible at low listening volumes, with a few seconds of lag after volume changes. Loses most of its bass off-axis. Customer reviews are mixed, ranging from praise for detail at low volume to complaints of a boxy, hollow sound.
What the Sony SRS-XE300 offers: IP67 rated. Orientation-aware playback switches to stereo when laid flat. Party Connect links up to 100 speakers; fast charging (10 min charge = ~70 min playback). Watch for: Muffled sounding, not very deep bass. Hollow sounding. Worse than a XB43
Buy the KEF Muo gen2 if sound quality matters more than the price. Buy the Sony SRS-XE300 if the price matters more than sound quality.
