I was completely unhappy with this product. I am not sure where the patented noise reduction technology that is advertised was but my family could not hear me due to background noise on interstated drives. When I was not on the interstate they said I sounded like I was in a hole. I was told I could return it (still out the shipping to and from) but now I can't find the box.I bought the new jawbone bluetooth that has gotten the highest Cnet rating ever and it is awesome. Spend the money the first time and get the best.
