Looking for Bluetooth headset with additional feature

Archived from groups: alt.cellular.bluetooth (More info?)

I'm looking for a Bluetooth headset that will also accommodate a
standard 2.5mm wired earbud. This is the ONLY one I found but it does
not seem to be a brand name and I'm a bit leary:

Reason I need this is my motorcycle has a communications system built
in and it connects to the cell phone with the standard 2.5mm male plug.
Now I'll be getting another cell phone that won't accommodate the
2.5mm plug so I need some way to interface to the comm system on the
bike.

Any suggestions would be most welcome!

Thanks,
Jacques
