@dayma I've bought it and am currently using it. You can't use acoustic CR neuro because like me your tinnitus is too high pitched. Levo is the only option.....
Regards price if you really want it unless your a student or unemployed you can afford it. On finance or a long term 0% credit card it's as little as 80 quid a month so that argument is ridiculous and when I see people on go fund me begging for help it's absurd. If you can't get a credit card I'm sure a friend can and you can pay them back. If you want it you can get it.
Look I'm not going to bang on about how I've found it, I think it's important that you do whats right for you but bear in mind you have to sleep with this on so my advice is try a few nights with just standard in ear headphones on...all night. See how you get on with your tinnitus sealed in and the discomfort of sleeping in them. If you're a back sleeper and your tinnitus isn't too bad you should be fine.
Also make sure you take an actual pillow with you when they fit their earbuds. I've gone back and forth trying to find a comfortable set and have not succeeded with their standard so called 'custom' ones. I found them very uncomfortable with a hard plastic 'driver' type thing protruding from the ear. I now have custom plugs of my own which I use with it.
Anything else you want to know just ask but to be honest it's not an easy thing to use and I certainly don't manage all night with it on but I'm trying to build toward it.
Please don't ask me if it helps because it's too early to say and as I said I don't want to encourage or discourage anyone on that front. Just maybe heed the above advice before spending the money cos if you can't tolerate the earbuds or sleep with the racket in your ears all night your not even going to get off to the races.
