Detects nearby microphones

This part seems like BS.

creates a 2m protection zone around you. It sends out signals that are inaudible to you but can be detected by a microphone

Plausible but anything inaudible to you and screwing with the remote is a software or hardware upgrade away. It’s hard to imagine a sw or hw bandpass filter doesn’t stop this. Also hard to imagine smart speakers aren’t doing this already to extract your voice in a noisy environment / personalize responses.

I’d wait for this to be independently verified and understand how they propose to find microphones. Maybe they’re looking for the Wi-Fi / BT signals the speakers are emitting but something like a local nanny cam there’s no way.

Perhaps they could do the audio+EM equivalent of LIDAR - put out a high frequency audio signal and than listen for EMF that matches.

A microphone is using so little electricity / voltage that I’d be surprised if you can detect anything even right beside it. It’s also not going to be tied to any fingerprint you’re trying to transmit.

And also do be doing positioning requires multiple spatially separated receivers (nothing like LIDAR). And good luck separating out other much larger sources of EM noise.
