I have had this product for about 4 months and am ready to replace it it! It works ok sometimes and the battery lasts about 2-3 days when you use it regularly...but the problem with it, is echoing and no noise cancellation...hard to use outside or in car with window down, because people complain about the NOISE. also sometimes people complain about an echo when i am on bluetooth, when i take it off bluetooth, the echo is gone.The best thing about this set is the volume. This is the loudest volume i have experienced in a bluetooth headset and very clear. Also It does stay in the ear nicely without worrying about it falling out.I am going to try one of the Samsungs that are out that have noise cancellation feature.
