It’s been a busy couple of months for smart speakers — Amazon released a bunch just this week, including updated versions of its existing Echo hardware and a new Echo Studio with premium sound. Sonos also introduced its first portable speaker with Bluetooth support, the Sonos Move, and in August launched its collaboration collection with Ikea. Meanwhile, Apple didn’t say anything about the HomePod at its latest big product event — an omission that makes it all the more obvious the smart move would be for Apple to acquire a company that knows what they’re doing in this category: Sonos.
