Best handsfree for mobile!

Well, I have always found that handsfree coming with retail packages are often bogus except few mobiles.

Now I am looking for a very good handsfree which is excellent in terms of sound quality. Kindly do NOT recommend any handsfree from any mobile as it is really very difficult to find handsfree of some mobile like W980 or whatever!

Moreover, that handsfree MUST be available in Pakistan because so far, I have seen that shops for good handsfree are rare.

Recommendations are really appreciated!
