Our Verdict

Bose SoundLink Flex

Sonos Roam 2

The Bose SoundLink Flex and the Sonos Roam 2 are both portable speakers that will appeal to different customers. Both speakers downmix your audio to mono, but the Sonos has much better directivity, so the sound is fairly similar regardless of where you are in relation to it. On the other hand, the Bose produces a bit more bass by default, although you can EQ the Sonos via its companion app, unlike the Bose. But mainly, the Sonos will appeal to people who are already invested in the Sonos ecosystem, especially because the Roam 2 supports the Sonos voice assistant. On the other hand, if you'd prefer to use your device's Siri or Google Assistant, the Bose is the pick for you.
