Short answer: the KEF Muo gen2, if you are buying new. The Sonos Roam measures as well as it (#83 vs #84 of 151 medium speakers, 3.1/5 vs 3.1/5) but is discontinued, so only consider it used; the KEF Muo gen2 is still sold new at $249.99.
Buy the KEF Muo gen2 new; the Sonos Roam is no longer sold new, so it only makes sense as a used find.

Cons: Bass extension isn’t very good. Not stereo. Gets distorted if you turn up the bass. Discontinued.

KEF Muo gen2: $249.99 Amazon eBay
Pros: KEF seemed to have fixed the rolled off treble and overall balance
Cons: 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.
