Controversial - IEMs at the gym

IEMs have spoilt us all alike. To the point that I can't stand my TWS buds except for when I'm taking calls.

I've used IEMs at the gym in the past but they were always super cheap ones, sub $20 or 30.

But after using more expensive sets, I can't seem to go back to super cheap stuff anymore either.

What kind of IEMs do you all wear at the gym? And how long do they last you? And is there some ways in which you take extra care of them?
