I have written about these plugs, and spoke about them everywhere I could. I suffer from Tinnitus due to a TBI while in service with the US Air Force. Day to day the ringing is a nuisance, but can become debilitating depending on environmental factors. You Regular filters help reduce high pitch sounds, which I am mostly sensitive to. Eating out in a restaurant, riding in a car with talking and the radio, or just sitting around with multiple family members speaking in different tones can irritate my sensitivities. These plugs have changed my routine life. When traveling, whether driving or flying (and sometime when big storm systems are coming through) the pressure changes cause terrible pain to my inner ear and head where the TBI occurred. Honestly, my husband purchased the aviation plugs just to see if they helped even a little. After 11 years, I just took my first flight without pain. I was able to land and immediate visit with family, instead of being laid up recovering, or powering through days of migraine's. I'm about to post my review and experiences in all the Veteran's pages I can find. THANK YOU! I realize these were meant for musicians originally, and as a musician as well I have once again been reminded the many ways music can heal.
