Short answer: the Minirig 4 on measured sound quality, the Sonos Roam 2 on price. The Minirig 4 ranks #6 of 142 medium speakers at $229.95. The Sonos Roam 2 ranks #74 at $179, $50.95 cheaper.
What the Minirig 4 offers: Modular, can easily attach a subwoofer. Finally USB-C charging. Dynamically changes sound based on forward facing or upward facing orientation Watch for: Calls itself splash resistant and has no official water rating. App is buggy. A bit expensive. Has reliability issues more often than any other speaker
What the Sonos Roam 2 offers: Very neutral. Additional button for pairing instead of being shared with power button Watch for: Exact same sound quality as the original Roam. Bass extension isn’t very good. Not stereo. Gets distorted as you turn up the bass.
Buy the Minirig 4 when sound quality outweighs the price for you, and the Sonos Roam 2 when the price outweighs sound quality instead.
There is a real battery-life gap here: the Minirig 4 is rated for 30 hours, the Sonos Roam 2 only 10 hours.
