I have just bought an iPhone and to be honest, I hate the headphones that come supplied - I always have disliked the standard headphones that apple supply...

As usual, I have my own headphones which I use and really like. So, what I am looking for is an Adaptor so that I can add a microphone. I know that there are numerous options I can buy, but none of what I have seen appear to be a viable option. The wire on my headphones is long enough to reach my pocket and still be loose when I walk. I really don't want to have to have that start at the microphone as it would be lots of loose wire dangling around looking nasty!

What I am after would be similar to a splitter... The microphone would plug into the iPhone as usual but rather than me plugging my headphone into the top, I would plug into the bottom, splitter. This would enable me to bring the Mic wire up and pin it to my shirt/coat/whatever and I would then have my headphones plugged in and have that wire the same as always.

Hopefully I have explained that well enough....

Is there anything like that already available?

Other than something like these, I don't think there is any. That Y design one you suggested sounds useful, but I can't find any

If that image is anything to go by, it is pretty much exactly what I am after :)
Thank you - really appreciated :D

Looking more into it, while the almost perfect solution, it appears to be for the smaller jack iPhones...

Thank you though - there may be a solution for me after all :D

Here's a page detailing how to put together a cable like you're after. If you can do a bit of soldering this is a cheap and easy way of getting a Mic onto an iPod Touch. Works with Skype and other recording apps:

Seems like this was made just for that purpose:
