For the curious or confused by the "when you tap the button it shoots an electrical signal that the phone will pick up and interpret" in the article, the control buttons are implemented as resistors switched across the mic/ground pair. The mic is 1000Ω or higher. The functions resistors are lower.

- hugodahl 10y agoVery nice and handy reference! Will give me something to compare against and my Pixel and Amazon headset. Apparently, vol up on the headset triggers the assistant, while all other buttons work as expected. Oddly, the same headset worked flawlessly on a OPO and Nexus 6. And Google hardware support cannot recommend a specific make/model, just one with "an on/off switch for the mic".
