If you like switching between computer, desktop phone and cell phone, this phone is for you. High quality and noise reduction. One thing it can't do, is go with you and the cell phone away from the base.
I was using a Plantronics Voyager Focus UC until it quit working after a few years. I was interested in this one since I could have 3 inputs instead of two, USB, analog headset and Bluetooth. The voice quality is not as good as the Voyager Focus UC. Using the USB and headset works ok, however, if you try to use Bluetooth, then the quality is trashed for all 3 inputs so badly that I have abandoned using Bluetooth.
I hate this product. I received it while I was out of the office for an unexpected surgery. When I came back I asked to exchange for a different product and they refused. Don't do business with this company I repeat don't do business with this company because after they take your money they don't care.
