good jack splitter

purchased for use with a Razer Orca headphones. The jack is both microphone and headset to a PC so it is necessary to separate the sheets to be used (otherwise it has no microphone and sound in one ear).
The razer orca using an old connection: this separator will not work with a handsfree newest iPhone like (I say this for those who buy without inquiring and moaning on the manufacturer).
The cable end, however, is a little expensive for my taste, but still cheaper than the splitter "official" Razer.
Good buy
