I bought this for my unibody macbook pro. In OS X I can use my iphone headset for chat programs but in Windows 7. I am forced to use the internal mic. I can't get it too work in either OS. You have to be a total noob if you can't get it to work in OS X.
The earbuds work; Thats about the only good thing I have to say about them
The earbuds have high pitched hum and the mic does not work at all
