Short answer: the Vifa Helsinki for midrange and treble, with a real usability caveat. The source says it is generally regarded as the best midrange and treble sound quality of any battery powered Bluetooth speaker, but it has no TWS pairing and needs a hacked Android-only app (post #48) to enable the night mode that makes it sound good. The Sonos Move 2 is warm with rolled-off treble and not very loud.
Buy the Sonos Move 2, since the Vifa Helsinki is discontinued and only worth hunting down used.
There is a real gap in water resistance: the Sonos Move 2 at IP56 (powerful water jets) against the Vifa Helsinki, which has no water resistance.
