Ok, flushed with the success of my wifi phone giveaway ...
I also have a pretty much as-new binaural VXI Passport headset using up too much space in the cupboard.
It comes with every different bottom-cable connector I could think of when I was doing some testing with it.
There are three different flavours of RJ9, plus 3.2mm, plus 2.5mm - so should be able to connect to about any phone.
If you are inthe UK and can offer it and the cables a good home, it's yours.
Any takers?
