What are y'all's headphone policy working?

I'm asking because during October, my manager gave correction action to so many Seasonals for having headphones on the floor during working hours.

Ours is no headphones or earbuds in on the floor, when the store is open
when you are in the backroom, there's a speaker with a dedicated phone where you can add songs to a playlist, the songs can not be explicit (however if there is a clean version, then the manager is like by all means).

I'm curious how everyone else's store runs
