New PC purchased during the sales summer 2014 but only one combo jack audio / mic while the headset that I use (games / skype) has 2 outlets ... By searching the Internet, I found the solution and bought this adapter. RDV quality, sound and microphone are the same as before and for less than 10!
PS: WTF of the moment !!! why manufacturers use combo jacks when the vast majority of headphones / microphone are sold with 2 sockets and adapters are found in the trade ...
