I will try David's Tinnitus Mix again. I did not give it a good trial yet. I tried a headband from Walgreen's, but my headphones still came off. I usually sleep on my side. I didn't try changing out speakers from the SleepPhones yet.
If a few of us here on this forum could try the soundmix for a few weeks we could evaluate it better. I'm willing to try anything for awhile.
@RaZaH is right about placebo effect on noise. It seems gabapentin plus a Seagram's Escapes beverage made my noise go away recently for a day or two. Whatever works for some temporary relief.
