I bought this product because I suffer from acute tinnitus and, on occasion even a slightly raucous conversation can cause it to start. I bought these primarily for a gig I attended in London, I knew that it was going to be exceptionally loud. I have read both good and bad points on these ear plugs. From a personal view they did exactly what I wanted, I could still hear every note and lyric played/sung, but it took the harsh echo off of it all, I actually took them out at one point to see the difference and it was amazing just how much these can filter out. I found that I could here my friends talking to me just fine. It does feel a little strange at first as you sound quite hollow spoken and it took me a little bit of time to get used to how loud I needed to be to answer people. I usually always get tinnitus from a gig like that for at least 2 days, and it is an immediate thing. I had none of it whatsoever, it was brilliant. I also now pop them in if I am in a crowded room, as again I tend to suffer when people shout in my ear, it is a little harder to hear at a normal speaking voice, but I feel these are the best ear plugs I've bought, allowing me to still enjoy a gig, but not loosing all the sound. Also the fact that they are clear really helps you feel more comfortable and not like your a coward for wearing them, my friends didn't even notice till I pointed them out. Your hearing is very important, not only is it annoying to loose hearing in one ear from tinnitus but it can also affect your balance, look after your ears and get these if you have a concern about harmful sound.
