Ok, I get what you are saying about headsets. I have not used them much at all, but have on flights with plugs. So hopefully the plugs have helped. But will stop altogether.
Using plugs will not make much difference. Headphones are bad for anyone with noise induced tinnitus. If one chooses to use them they risk their tinnitus becoming worse. I know some people find this hard to believe but the evidence is there, just read some of the many posts in this forum from people that have NIT and regret using headphones. Something has caused your tinnitus to increase, in most situations it is either headphone use or exposure to loud sounds that causes noise induced tinnitus to become worse.
This still confuses me. If you think my increase in tinnitus is from some source of sound, yet I may be over protecting, I can't win.
I am not saying over protecting necessarily causes tinnitus to increase. However, it often makes the auditory system more sensitive to sound.
Try to see a Hearing Therapist or Audiologist that specialises in tinnitus and hyperacusis management and treatment.
