If you are like me and don’t like the headset supplied with the iPhone and wanted to use Shure or Etymotic or Ultimate Ears earphones with your iPhone. This is the first good accessory that converts your earphones into a stereo mobile headset for iPhone. The inline VoicePort microphone delivers clear voice regardless of the background noise. The control button enables you to send and end calls. You can also use the button to play, pause and forward songs just like Apple’s headset.  You can buy the adapter online on Apple Store for $39.95.
