Hello, just for your information, I recently purchased an app from Apple for my iPhone called Tinnitus Pro, cost about $10, the product is developed by PRO-Medical. It allows you to set and preset "notched music" to your specific loudness at any particular time. I've been using this product for about a month now, and seems to work better with headphones as opposed to ear buds, good quality ear phones! I play songs that I know have a lot of high frequency sounds in them as my tinnitus sounds are in the 8500k range, on this product you can see where the music is being notched and what frequency is being withheld. I don't know if it's working yet but for $10 it was worth a try. If it doesn't work in the months to come I still enjoy listening to my songs and masking tracks. Check it out, costs nothing to look at at, just remember I don't endorse this product yet, I've only been using it for about a month.
