Thanks Pandalet - I wish I'd known about these before I bought the Bose - they look really good! This is what it says on the Lightspeed web!!!!e: "Cell/Music Connection Wired interface for patching in cell phone, or music devices with supplied cables."
They come with a LEMO plug option too, so as a last resort I could change just my headset, but if there's an aftermarket something for the Bose X, obviously that would save me £600 ish...
cheers
