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?

I think u/02K30C1 has the best answer here… but I wanted to reply and say that your question is a bit misleading because they can interfere with each other.
As a commuter who goes between NYC and NJ, if you walk through the Oculus at One World Trade (where multiple subways converge in addition to shops and military personnel), you’ll experience this.
It’s a lot of stop and starting and odd pauses, so interference via Bluetooth does happen! It just takes a lot more people and devices.
