iPhone Headsets?

Where can I find iPhone headsets? The original ones from Apple that have the microphone built into the cord.

I know the iPhone it not yet officially available in Taiwan, but many shops have iPhone accessories. None yet seem to have the iPhone headsets, including the 3 Apple stores that I have checked in Taipei.

Were you actually happy with them?
Why would you want another pair?
There are much better alternatives available.

The standard headsets serve the basic purpose, and the others that I have seen seem to be more bulky and more complicated to use.
