What headphones can connect to the iPhone?

Can you connect below the headset into the iPhone: – If http://www.apple.com/uk/ipod/inearheadphones/ not those who can communicate? Thank you.

I'm sure you can connect the headphones to the iPhone 3G. They have a four conductor of 3.5 mm audio jack and the iPhone 3G has a mini-jack 3.5 mm stereo headphone.
