I have a late 2008 MacBook Pro and while I think it's cool that I can use iPhone headphones with it I miss using my old school analog headset with a boom. I use skype for calls and find that people have a hard time hearing me with iPhone headphones. Is anyone aware of a splitter for that jack so that I can connect a headphone line and a mic line? I've seen lots of solutions that have a built in mic but I was hoping that there's simply a splitter out there somewhere. Thanks.
