Short answer: the KEF Muo gen2, if you are buying new. The Denon Envaya DSB-250BT ranks higher than it (#5 vs #76 of 142 medium speakers, 4.4/5 vs 3.1/5) but is discontinued, so only consider it used; the KEF Muo gen2 is still sold new at $249.99.
The case for the Denon Envaya DSB-250BT: One of the early Bluetooth speakers with excellent all-around sound quality, very neutral and great soundstage. Set against that: Expensive.
What the KEF Muo gen2 gets right: KEF seemed to have fixed the rolled off treble and overall balance. The catch: Lacking deeper bass.
Buy the KEF Muo gen2 new; the Denon Envaya DSB-250BT is no longer sold new, so it only makes sense as a used find.
If battery life is a priority, the KEF Muo gen2 is rated for 24 hours versus 13 hours for the Denon Envaya DSB-250BT.

Denon Envaya DSB-250BT: $250 Discontinued eBay
Pros: One of the early Bluetooth speakers with excellent all-around sound quality, very neutral and great soundstage. Deep bass without distortion at high volumes. IP67 waterproof and dustproof rating. USB charging port charges mobile devices. Built-in stand on back for sturdy tilted positioning. Measured bass extension of 57Hz (-10dB).
Cons: Expensive. Treble is rolled off. Phantom battery drain issue, would not recommend these days. Uses some stereo enhancement reverb that can sound weird to some. Not as detailed as higher ranked speakers. 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.
