I wanted a microphone / standard headphone adapter for the PS3, and it is absolutely the case. During voice chats means good and I hear very well my interlocutor. For those who, like me, do not want to buy micro / bluetooth headset for their PS3, since they already have a microphone / headphone jack classic for their computer, this key is the solution. To be recognized, once plugged into the USB port of the console, go to "Settings" / "Accessories settings" / "Audio Device Settings" then select "USB PnP Sound Device" as the input device and output. We can then play online with his microphone / headset connected to this classic key.
