Purchased more than one adapter for the headset has two plugs ... one for the microphone and one for sound. Unfortunately, I misread the description of the product and I had this "good" surprise that my PC had only one connection Jack. Otherwise, thank you for the product. Inexpensive, despite the quality a bit "plastic" at the edges, I do not care for aesthetics and dedicates it 5 stars because it meets my expectations and hopes. Used to solve problems on my conversations Skype (very functional microphone speaker on my Lenovo ...)
