im not sure about an alternative because i really like the original headset. my n9 shipped with a wh 701 which sucked enourmosly thats why i bought the wh 901 from here

of course its a german website, but all you have to do is google for "nokia wh 901 bulk" read descriptions exactly...sometimes resellers claim to sell "wh 901" when it really is a "wh 902" with an adapter for common nokia av jack. the adapter thing sucks and leads to a non-functional headset-remote..
