mm50 and blackberry

Hi all,
I currently have an 8330, looking at getting a 9650 in the next week. I was looking into a better headset than the one that originally came with my phone. I also had a pair of CX200 earbuds and loved them... so I came across these Sennheiser MM50 iP earphones with a built-in mic. They are designed for the iPhone, but I was wondering if they would work on the blackberries too.

Anyone have any experience with the MM50 or any other iphone headsets working on the blackberry?
