Short answer: the W-King D320. It ranks #49 of 177 medium speakers by sound quality, rated 3.6/5, at $52.92; the Sonos Roam 2 ranks #94, rated 3.2/5, and costs $179, so there is little reason to consider the other one.
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 W-King D320 at 3.1 lbs (1.4 kg). The tradeoff: Exact same sound quality as the original Sonos Roam.
The W-King D320 is the better-sounding, longer-running pick. An affordable waterproof travel speaker with loud, punchy bass, long battery life, an aux input, microSD playback and app EQ. It is rated for 24 hours of battery against 10 for the Sonos Roam 2. It is rated IP67 against IPX5 for the Sonos Roam 2. It keeps a wired aux input, which the Sonos Roam 2 lacks. The catch: A single D320 is not stereo, and its warm balance trades away some detail and upper-treble air.
Buy the W-King D320. It is rated higher for sound quality than the Sonos Roam 2 and costs less, so only choose the other one for a particular feature it does better.
