Found this on
Reddit from a person that says they were one of the recruited volunteers:
"
How did you get your tinnitus? How long have you had it?
Some combination of childhood ear infections, noise exposure and benzo drug exposure caused me to first notice the condition during a period of severe anxiety in 1999. It was stable and not especially distracting until it became violently worse following a concert in 2010. (As a result of the tinnitus, I was generally very good about earpro at shows and even bars, but, just like with birth control, all it takes is one screw up).
After 2 weeks of use, my tinnitus was less intrusive, somewhat harder to hear in environments with ambient noises going on, and generally I found it much less distressing and on my mind a lot less.
They're
hoping to be on the market in the early 2020s, but who knows -- if the phase-II study doesn't produce good results, then it's hard to say what'll happen."
