Short answer: the Sonos Roam 2, if you are buying new. The JBL Flip 4 ranks higher than it (#82 vs #92 of 164 medium speakers, 3.3/5 vs 3.2/5) but is discontinued, so only consider it used; the Sonos Roam 2 is still sold new at $179.
On the JBL Flip 4 side: Less bass than a Flip 5. Watch for: Battery failures are common.
Buy the Sonos Roam 2 new; the JBL Flip 4 is no longer sold new, so it only makes sense as a used find.

Older model: the Sonos Roam (ranked lower, rated 3.1/5).
Pros: Very neutral. Additional button for pairing instead of being shared with power button. Measured bass extension of 63Hz (-10dB).
Cons: Exact same sound quality as the original Roam. Bass extension isn’t very good. Not stereo. Gets distorted as you turn up the bass.
