They have yet to even be sent to ups. Sooooo I dunno
I found these while I was looking for normal noise reducing earplugs for shows and decided to order these as well. I recently developed issues equalizing pressure in my ears during flight descents. The last few flights I’d been on, my ears had been unable to pop for days to weeks after. I always use the smallest size earbud too that comes with earbuds, so I got the small size in both the aviation and regular ear plugs and they both fit perfectly. Comfortable to wear in flight, and after 2 flights I had no lingering ear pressure issues afterwards.
I actually have expanded It's use to using it also For eustation tube blockage & they keep the pressure In my ears balanced on Flat land or hill top!!!
So far I have really been enjoying these plugs. I have certainly noticed the difference it has made in my air travel. I recall traveling with friends and hear them complain about the ear popping while I was feeling perfectly fine. The only "bad" thing about them is that you have to make sure you don't drop them because finding them will be a challenge in of itself :). I certainly would recommend this product to anyone that is looking for a solution to this ear popping inconvenience.
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.
