I have the Jabra BT530 headset and it works great.

BUT, one of my cars is loud and a wired headset works best. Trouble is finding one. I would like a Shure or something similar. They work best on a plane or when cutting the grass. Everything seems to be made for the iPhone.

So....any idea what works? I know it's a 3.5mm but 3 pin or 4 pin? Will an iPhone set work? How about Blackberry?

The ironic thing is that after all the years of wanting a 3.5mm jack and being stuck with a 2.5mm jack, I might still need to use an adapter.
