Our Verdict

Sonos Roam 2

Bose SoundLink Flex (2nd Gen)

The Bose SoundLink Flex (2nd Gen) and the Sonos Roam 2 target different kinds of customers. If you're invested in the Sonos ecosystem, the Sonos speaker is likely the better choice, especially since it has built-in support for the Sonos voice assistant and Amazon Alexa. If you'd rather use your Android or Apple device's voice assistant, the Bose might be the better pick. Neither speaker is a great choice for fans of tracks with complex stereo panning, as they both downmix your audio to mono. However, the Sonos speaker's wider directivity means it has the edge here, as it produces audio that sounds fairly similar at wider listening angles.
