Here’s something better I’ve found to improve on it: you can get a $30 massage gun from Amazon with one of those round soft heads, gently put it to the back of your head where doing the manual exercise above hits with your fingers and run it at the slowest setting. It’s exactly the same thing, and it’s very effective for shutting off tinnitus. I do this when mine gets bad.

I’ve also noticed my tinnitus is inversely proportional to the last night’s sleep quality for me, so the article bears out on an anecdotal standpoint.
