Yeah, I will stop using them for now. I guess it was because I found that headphones didn't really cause any issues.

I am going to give you some advice. You can follow it or ignore it. Count yourself fortunate that your tinnitus has reduced to a level where you are able to carry on with your life doing everything that you want to. With the utmost respect, wanting to use headphones is a very silly idea because it is not a matter of if, but when your tinnitus will return with a vengeance. I believe the symptoms that you are experiencing are warnings that your ears and auditory system do not like music played through headphones.
Can the auditory system suddenly get oversensitive, though? Or must there be something that causes it to happen?
It is my firm belief the oversensitivity to sound that you are experiencing is caused by headphone use. If you stop using headphones now and never use them again then I think you will be alright. Continue using them or return to using at a later date you may not be so fortunate and get a warning, as your tinnitus may suddenly spike and remain at a high level.
All the best
