I've tried Tinnitus Mix for 2 nights, 1 hour the first night, around 2.5 hour this night... couldn't sleep with the headphones on, uncomfortable since I can only sleep on the side and they press against my ear. I will try again though.
Anyways, it's certainly a bit interesting. The day after the first 1 hour test (+ perhaps 1 hour in the day); the tinnitus got more lively, not louder, just more activity. At one time my tinnitus even sounded like a certain part from the Tinnitus Mix, which was very odd, kind of an up/down scraping, never had that before. Overall the tinnitus was less of a constant tone and more varied and lively. Can't say I particularly liked that, not an improvement.
Today, after the second try of around 2 hours... no change in the morning, the usual constant tone was back. But now a few hours later its lower than it has been for a very long time. How I "test" my tinnitus is to watch something on YouTube - is the tinnitus in the foreground or is it more in the background? It's more in the background currently, more easy to forget that its there.
Everything here could be coincidence, absolutely. I've had peaks and lows since I got it so... The reason I googled and found this site and thread is because I've peaked a lot in the recent 3 months, it's been in the foreground for a long time which has really lowered my mood.
I'm certainly going to continue, hopefully being able to sleep with headphones on.
