Likewise, I rarely use it but I have developed some off and on tinnitus in my other ear which is at a different pitch altogether which can be annoying as hell. On those occasions I may use something. Your YouTube link worked well. I downloaded the sound of a open water faucet which was my orginal discovery while shaving.
I have had brief moments in the shower with the water hitting the back of my head that it felt like the sound was gone. Also floating in the sea with waves coming over my head. You cherish those moments as rare as they are, but eventually, it's fine.
