Do not waste your money on this product!! Whilst Amazon has a very good price for it, the headset is junk! I tried two different sets and both had a terrible hum. The hum was audible at all jacks in the house and on two different phone lines. It could be heard by the other party and made my hearing the other party nearly impossible. I work for the phone company and have used headsets over the past 25 years with no problmes. This set is very poor quality and not worth the money.
