Our Verdict
Bang & Olufsen Beosound A1 Gen 2
Sonos Roam/Roam SL
The Bang & Olufsen Beosound A1 Gen 2 and the Sonos Roam/Roam SL are similar speakers with different strengths. The Bang & Olufsen has better directivity, resulting in a wider-sounding soundstage. Also, it has lower Bluetooth latency with iOS and Android devices, making it more suitable for watching movies and videos. The Sonos offers a slightly better-balanced sound profile and fantastic voice assistant support with its Roam variant. It's also Wi-Fi compatible and supports Apple AirPlay 2, which is ideal for Apple users.
