I got tinnitus before ANC was a thing, and I've never been able to comfortably use it for more than a short period of time.

Whenever I do, I swear I feel increased pressure on my ears and my tinnitus temporarily gets worse. I've often wondered if I imagine it, but hearing from others here makes me think it isn't so strange.

Oh weird, I also perceive an increased pressure on my ears, but it's only with my over-the-ear headphones when turned on. My in ear ANC headphones don't do the same.

Slight tinnitus here but had it for as long as I can remember.
