Short answer: the Minirig 4. It ranks #7 of 177 medium speakers by sound quality, rated 4.3/5, at $229.95. The Sonos Roam 2 ranks #94, rated 3.2/5, at $179, $50.95 cheaper, not enough of a saving to outweigh the sound-quality gap.
The Minirig 4 is the better-sounding, deeper-bass option. A small, long lasting speaker that gets loud and can add a matching subwoofer, with a 30 hour battery. Its bass reaches about 56Hz before falling 10dB, against 63Hz for the Sonos Roam 2. It is rated for 30 hours of battery against 10 for the Sonos Roam 2. It keeps a wired aux input, which the Sonos Roam 2 lacks. The tradeoff: Calls itself splash resistant and has no official water rating.
The Sonos Roam 2 is the lighter choice. A small Wi-Fi and Bluetooth speaker with water resistance, Alexa built in and Sonos multiroom support. At 0.9 lbs (429 g) it weighs noticeably less than the Minirig 4 at 1.2 lbs (550 g). Watch for: Exact same sound quality as the original Sonos Roam.
Buy the Minirig 4. It is rated higher for sound quality, and the $50.95 you would save on the Sonos Roam 2 does not close the gap.
