I had this thought just now at the gym. I noticed multiple people, myself included, using wireless earbuds during our workouts – specifically AirPods.
My question is, if multiple people are using AirPods that work on the same frequency/signal, how come our music doesn’t all interfere with each other? How do each of our phones/AirPods differentiate from the others a few feet away from me?
In: Engineering
They’re not all actually using the same frequency. They work within a spread of frequencies, and your phone and the headsets work together to find a clear space within that spread and avoid bumping into other people’s phones and headsets.
That’s an extreme oversimplification but that’s the general gist of it.
