Can headphones be worn when you have a perforated eardrum?

Both of my eardrums are perforated after an gromits operation when i was about 10. Now aged 17 and after many years of listening to music on full volume through earphones/headphones it has not effected my hearing. The only issue i have is an aching in my more affected ear after a while of constant loud noise while using earphones, say when watching a film with no breaks. I'd wear them but keep the volume down if it causes discomfort.
