I am experiencing the same
Exact symptoms. All deep voices Nd intermittently with high pitched Voices, have not noticed it with whispers. Sounds like a computer voice. When I'm having the sound distortion , I appreciate the effect better with both ears unoccluded. If I cover one ear it is still present but much less noticeable. Same when I cover both. When I cover the ears, I hear the effect better in my right ear. I have no other symptoms:no fever
pressures, sore throat
, runny nose, muscle aches. I don't have ear pressure sensTion either. The only recent changes to my daily routine I can think of are: recently started playing guitar through my iPad using it as a amp and playing it through the earbuds. It went off loud with some feedback once a few days ago. Recently started new dose/formulation of extended release add meds. One of my buds is sick with upper resp infection. Lol so many factors in the right time frame .Did your symptoms go away? Did u figure out what it was?
