The Sonos Roam may be the best portable bluetooth speaker on the market. Not only can it connect to the Sonos app to stream music over Wi-Fi, but it also supports Bluetooth and AirPlay 2. Furthermore, it features up to 10 hours of music playback support, an IP67 water-resistance rating, wireless charging, and support with Amazon Alexa or the Google Assistant. My guess is this will be Sonos' best-selling speaker to date just because of how feature rich this product is.
