These are not really the same size class, and that is the honest framing here. The Denon Home 350 ranks #9 of 10 powered desktop speakers by sound quality at $749; the Sonos Roam 2 ranks #93 of 178 medium speakers by sound quality at $178.
The case for the Denon Home 350: A large Wi-Fi smart speaker that plays loud, with lossless streaming, built in Alexa that hears you well, and app tone controls. It keeps a wired aux input, which the Sonos Roam 2 lacks. It plays in stereo from a single unit, unlike the Sonos Roam 2. The tradeoff: RTINGS measured a slightly boomy sound profile out of the box and disappointing directivity, so the sound changes noticeably off to the side of the cabinet, plus compression artifacts as it nears max volume.
The Sonos Roam 2 is the battery-powered, tougher pick. A small Wi-Fi and Bluetooth speaker with water resistance, Alexa built in and Sonos multiroom support. Its battery is rated for 10 hours, while the Denon Home 350 needs an outlet. It is rated IPX5, while the Denon Home 350 has no water resistance. It supports AAC Bluetooth, which the Denon Home 350 lacks. The catch: Exact same sound quality as the original Sonos Roam.
Buy the Denon Home 350 at $749 for a powered desktop speaker, or the Sonos Roam 2 at $178 for a medium speaker instead.
