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?

Because each person’s earbuds are paired to their phone. You are thinking of it more like a radio signal, where any device is able to intercept the signal, but it doesnt work like that for a paired device. Each device has a signature that is recognized by the other device it is paired to, and signals can only go back and forth between the devices when they both agree to share their signatures through pairing
