Excellent resource to protect your hearing
I bought these as the ringing in my ears has gotten worse over the years and I decided to try to do something to protect my hearing.  I just used these during about 30 minutes of impact drilling into concrete and my hearing was completely unchanged instead of the high pitched ringing I usually get after being around this type of noise.  Additionally, the Nonoise ability to not block all of the higher pitches sounds is significantly better than any other sound blocking device I have used.  You still get a bit of that 'underwater' hearing effect, but not nearly to the extent of even most sound dampening headphones I've tried.  Talking to people while these are in was significantly easier as well.  I would recommend these to anyone trying to protect their hearing and look forward to trying these at the next concert I go to.
