Loved those headphones. I forget what defect mine suffered from, I think they were ultimately bricked and I was offered a sincere apology and a full refund well over a year after purchase -- some of the best support experience I've ever had.
What's your definition of a car person? I don't care for the guy, but having multiple modified super cars and building several custom trucks in the past -- he seems like a car [truck] person to me?
That's sort of how it works. The car "wakes" the key up to auth with it when you touch the switch on the door. The relay attack is bidirectional so it replays both the wake up from car to key and the response from key to car.
