Product Review (submitted on December 14, 2012):
I was unsure of the claims, but the price difference between locaL stores and Century's was too great not to try, plus they offered a money back guarantee. I couldn't resist! I ordered them and was more than satisfied! I now hear sounds never heard before! The high frequencies are crisp and clear. For me I am sorry I didn't get them sooner! My gal pal is also happier now as I am able to hear her speak, as she has a high pitched voice. Also one small problem occurred about battery life. I returned one that had the problem and soon it was returned good as new! I would highly recommend any one to give Jon a chance to prove his claims, you won't be sorry! I rate Century a 5 star rating, hands down!
