Best headset for people with sensitive ears

Hello guys,

Recently, some guys at my gym have been playing hard metal really hard at the gym, and i cannot stand loud noises at all, so im looking for some really good headsets to wear to the gym with an excellent sound isolation.

For the budget, I'd like something that doesn't go over 300$, but if it's not enough i can go up to 500.

I'd also like something pretty sturdy since i think I'll be wearing them.

Thanks for any advice
