I'm very curious, does your reference to hurting mean an ache inside the 
ear? I had some NCT noise-cancelling headphones, but they gave me a 
pressure headache when I wore them, so I stopped after about a week. I 
was concerned that while I couldn't perceive sound, the pressure might 
be causing my ears damage.

I now wear custom fit earplugs inside my ears instead, and they are very 
comfortable while taking the edge off the background noise.
Thanks, Allan
