I’m having a problem getting music just thru my AirPods 2 when other Apple devices are in the same room even though they have different id’s!! How to do I get music to just play thru my AirPods??

I clean for someone and I want to listen to my AirPods. But the problem is is that they have iPhones and other Apple devices that when I attempt to play music it doesn’t come to my AirPods (I’m actually not sure where it goes or where it plays)

so how do I get music or whatever thru my AirPods 2 when other Apple devices steer in the same room but different id’s.

I’m so confused

I’m new to apple was an android person for years
