I discovered that my "magic" touch doesn't just work on watches. Two weeks ago my mouse died and I had just changed the battery a month prier. So, I gave it a try and did the same thing I do with watches. It worked. As a matter of fact it has been working ever since. So, I figured I would give it try with my cordless headphones. There's no batteries involved so, I didn't expect it to work. I don't have any speakers, just the headphones. When I ran out of power in the middle of a movie I thought eh, why not give it a try. It worked. I got to watch the rest of my movie before I had to recharged the headset.
