I am not a doctor, but I would NEVER use headphones or earbuds having Tinnitus. I am only saying this because I don't want it to get worse for you. Make sure your ENT approves of this.
This is a grab from Google
People with Tinnitus Should Avoid Earbuds, Earphones, and IEMs. In-ear monitors (IEMs), also called earphones, sit directly in the ear canal. ... The sound energy in IEMs is directed directly into the eardrum, which can be irritating or even harmful for people already suffering from hearing loss or tinnitus.
