Sonos is offering a special limited deal for its new Sonos One smart speaker, which works with Amazon’s Alexa right now, and is gaining support for Google Assistant in a future update: You can buy two for $349, which is the same price as one of Apple’s HomePod Siri-enabled speakers. This is likely not a coincidence.

Individually, the Sonos One retails for $199, so you get a $50 discount when you buy two. Sonos has offered similar pricing on the Sonos Play:1 in the past, but the discount on the new One means you get a newer model, with ambient microphone and smart assistant capabilities thrown into the mix.
