Best Hearing Protection: Isotunes and understanding The NR Rating

Even tho it isn't a glorious tool, it is extremely important to use hearing protection whenever possible. Currently I am loving my Isotune Free's, but I also wanted to help share some info I learned about the NR Rating and how to understand it. The important thing is to make sure your hearing protection of choice is working properly.
While this video isn't just about Isotune Hearing Protecting, I am asked all the time about them and my opinion. I have had really good luck with them and I love how comfortable they are all day. Another huge bonus is the ability to connect thru bluetooth to your phone and listen to music, take phone calls, or just use them as noise canceling ear plugs.
