This is a Great product!! I am enjoying these features of not having a cord connected and the cancelling of the background noise is a Big Deal for me since I am required to have no background noise while I am working from home... Even though I purchased this at a cheaper price since it did not have the original box and no manuel, I cannot complain! The Quality is Awesome!! I did go on line and found the manuel and also called the Tech support since I was not getting a dial tone and they were able to quickly show me how to correct that problem immediately in only a very short time....
