My wife and I wore these when we went to Electric Forest and the made the experience so much more enjoyable. No ear ringing. No headaches. Much more comfortable then the ear plugs we used to wear.
I swim a mile in open water (weather permitting) or pool a mile 3 to 4 times a week and have been using Fen X ear plugs for about 3 months and love them. I can hear with them in and no water is getting in my ears.
As a motorcyclist, these earplugs blocked out wind and other loud, damaging sounds without making everything you want to hear sound muffled or distorted. They're comfortable to wear and are custom molded to your ears. They make it easy to do the right thing and protect your hearing while making the riding experience better, not worse.
The scan on my ears was fast, easy, and totally non-invasive -- the custom plugs fit perfectly. I keep them handy in my purse, it's so easy to just slip them in. Very comfortable and you can barely see them. I wear them in the office whenever I need to concentrate.
I use these ear plugs for Target practice and when I am duck hunting and I can honestly say, I have never owned a better pair of hearing protection. At the range it's gets loud and I can still hear my friends talking. I highly recommend them!
