I have used this new BT headset for the last week, it was shipped to my store by plantronics as a demo before we get inventory, it is simply amazing!!! I cannot believe the clarity. EVERY SINGLE PERSON I have spokenwith on it was in awe that I was on a headset, theysaid it sounds the same as my phone. It has some new noise cancelling technology that really does work! I have used countless headsets, and every single one has "snap crackle pop" effect,and people on the other end can tell I am on a headset, not the case with this one, I highly recommend it!
