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?

How do you speak with other person in a crowded room? You raise your voice (increase transmission power), you exclude every tone of voice not belonging with your interlocutor (filters and channels). If you could you would change tone every time you speak with the other person and you would change even language so that nobody could understand you (frequency hopping and encryption).
