No, basically everything widely available now won't work with the N9 as everyone standardised on the "other" layout. In fact the writing was already on the wall before the N9, but they seemed to stubbornly stick with the "old nokia" layout.

That and the finicky not-quite-lenient-enough USB charging are for me the two main hardware annoyances with the N9, but that's another rant.

You'll need an adapter as above, or to source an N9/Symbian flavour old headset.
