Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The Brane X ranks #4 of 117 large speakers by sound quality at $549; the Sonos Roam 2 ranks #93 of 178 medium speakers by sound quality at $178.
The Brane X is the deeper-bass, tougher choice. A portable speaker with extraordinarily deep bass for its size, plus Wi-Fi, AirPlay, Alexa and a low latency aux input. Its bass reaches about 31Hz before falling 10dB, against 63Hz for the Sonos Roam 2. It is rated IP57 against IPX5 for the Sonos Roam 2. It supports aptX HD Bluetooth, which the Sonos Roam 2 lacks. The tradeoff: The front-facing design has only moderate dispersion, so sound changes noticeably off to the sides or behind it.
The Sonos Roam 2 is the lighter option. 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 much less than the Brane X at 7.7 lbs (3.5 kg). The catch: Exact same sound quality as the original Sonos Roam.
Buy the Brane X ($549) for a large speaker; the Sonos Roam 2 ($178) suits a medium speaker instead.
