Bose Lifestyle Ultra Speaker

The Bose Lifestyle Ultra Speaker supports wireless streaming over WiFi and Bluetooth (including Bluetooth Low Energy), and it explicitly supports Apple AirPlay 2, Google Cast, and Spotify Connect. These are listed in the review's specification and description. Answered

Yes. The article says the Lifestyle Ultra Speaker can be paired with a second Bose Lifestyle Ultra Speaker for an enveloping stereo experience and the specifications list a Stereo Mode when enabling two speakers. To set it up you must use the Bose app (Android or iOS), create or sign into a Bose account, connect the first speaker to your WiFi, and then use the app to add and pair a second Lifestyle Ultra Speaker as a stereo pair. The app is required for initial setup and pairing but offers only basic Bass, Mids, and High adjustments once paired. Answered

The Bose Lifestyle Ultra Speaker has no battery and is mains-powered only. The specifications list "Battery: None," the box includes a power cord, and the review states it requires a power source and is not a portable, battery-powered speaker. Answered

No. The article states the Bose Lifestyle Ultra Speaker is not a home theater speaker or soundbar replacement on its own and needs to be paired with a Bose Lifestyle Ultra Soundbar to connect to a TV and create a surround sound setup. It also notes that even two Ultra Speakers cannot be connected to a TV or home theater unless used with the latest Bose soundbar. Answered
