Conveniently leaves out the part:

“The microphone has never been on, and is only activated when users specifically enable the option.”

I'd also venture that if you were interested in the Nest Protect device, there is a 99.99999999% chance you already have a smartphone (with a mic), a smart tv (with a mic), a Google assistant (with a mic) or an Alexa (with a mic), or on and on and on.

Damn near every "smart" device you can buy now has a built in mic and probably camera, and if someone is too stupid to expect that, they probably shouldn't buy it in the first place.
