One SL does not include microphones and therefore does not have built-in voice control. Otherwise, the two speakers share the same features. You can still use other Sonos speakers, like Beam and One, or Echo and Google Home products to control One SL with your voice.
One SL features the same great sound and humidity resistance as Play:1. It adds Apple AirPlay 2, capacitive touch controls, and the same monochromatic color finish as One. Unlike Play:1, One SL can be stereo paired with One.
Yes. The sound and acoustic properties of One and One SL are identical.
Yes. All accessories that work with One, including mounts, power cables, stands, and shelves, will work with One SL.
One SL is great for stereo pairing or using as home theater rears with One or Beam, which include microphones. (There is no benefit to having multiple products with built-in voice control in the context of stereo pairs and home theater systems.) One SL is also perfect for rooms where you don't want or need a speaker with voice control.
Currently there are no feature differences between Sonos One Gen 2 and the original version. The original Sonos One will continue to support all its current features, and more, in the future. Over time, however, the increased memory, Bluetooth Low Energy, and processing power may allow us to bring new product experiences to the Gen 2 version that the original will not be able to support. That said, we have no specific Gen 2-only features planned at this time.
Yes, the Gen 2 works seamlessly with the original Sonos One as a stereo pair or home cinema surrounds.
Bluetooth Low Energy (BLE) was first introduced with Sonos Beam, and now we are bringing it to Sonos One Gen 2. Just like with Beam, BLE can be used to communicate temporarily with your phone or tablet to simplify the first-time setup process. BLE does not support audio streaming. Once setup is done, Sonos One Gen 2 streams and updates via your WiFi just like the original Sonos One.
Sonos One Gen 2 is marked as “Gen 2” on the product label underneath the speaker. The original Sonos One only has “One” on the product label.
