Summary: I purchased this headset to use with skype, but I have intermittent issues with it that require me to reboot to reset the sound. I also use it while playing games and it does not work well with a game called smite. There is a constant squeeling sound that makes it unusable.
Summary: I searched for a specific model #, and the item that showed in results did not mention that it was NOT what I searched for, I had to return the item ($6 Freight) as it did not have a USB connection. Very misleading to NOT mention that the item was not the model # that was searched for.
Summary: I bought this to replace one that finally quit working after about 5 years of hard use. You do need to follow the instructions and set up the dials under the cover on the base or you will sound like you are in a tin can to the people on the other end of the line.
Summary: This product works easily with my Cisco IP phone at work (call center). I didn't have to have IT install it. I am able to walk around seamlessly. The only downfall is that the headset does not ring on an incoming call. You have to hit the button on the phone base station to answer the call.
