I always thought that RMI where powerful enough to rip off anything metal. I had a RMI for a knee injury recently, and even though I didn’t need it (I find being in a tube with white noise relaxing) I was given a headset to listen to some Verdi (I’m more a german romanticism guy but can’t choose the tune).
It made me think about those experiments when someone in a RMI is subjected to changing images to see how the brain works.
How any of those things work in a highly magnetic environment ?

Do you mean MRI?
If you got headphones to wear while doing an MRI, it’s likely that the MRI isn’t being done anywhere near your head. Especially considering you said you had a knee injury. There’s enough of a distance to prevent the MRI from being interfered with or interfering with other objects that are magnetically sensitive or just ferrous in nature.
You would know if the MRI was active and scanning anywhere near anything metallic etc.
I have a copper BB embedded in my left optic nerve. I had to get an MRI done so the doctors could figure out where exactly it was and how to treat the damage. They had to turn down the MRI and take multiple scans before they could get a result. Let me tell you, when they’re scanning you with an MRI and you have something on you that shouldn’t be there that reacts to the magnetism of the MRI, you will feel it and feel it lots. While getting my head scanned, I could feel the copper BB being pushed and pulled by the scanner. Most excruciating pain I have ever felt in my life. Being shot was less painful.
Yeah, its a long air tube, remember that sound propagates in air (you can’t shout in space). So its not electricity in the wires that it gets converted to sound in your ear (like normal heatsets are). In MRI heardsets, the sound is made out of the room and sent to you via small air tubes. They are blasting music from outside the room, just channelled through a tube.
They make MRI safe headphones. There is nothing electronic in them. It’s similar to the old airplane ones that are just a big long tube. So the speaker is somewhere else, sound travels a long distance in a small tube, all the way to your ear
