If you make calls, you'll get an echo effect. To be more exact on what it is, please read this email that I got from Westone CS regarding the effect. Ignore anything dealing with the iPod (my inquiry was about the iPod Touch):

Thank you for your email. The echo effect being experienced is by the person on the other end of the phone call. It will not affect the sound quality if you are using the device for listening to music. If you are using the iPod to make calls to someone using an app we cannot say with certainty if you will experience the echo effect or not. The EPIC MICS cable has been tested only on smartphones and has not been tested on the iPod Touch or any other WI-FI phone devices. If you have any additional questions please let us know. Thank you and have a wonderful day!
So what happens is that the person on the other side of the call apparently will hear an echo and that may cause communication problems. I think it may have to do with the way that the iPhone's antenna on the 4/4S is actually around the rim of the phone and there is some interference going on. I can't confirm that though.
