I managed to get my pair of BT450RX i-PHONEs to work but only after hacking the BT stack thanks to the tips here. Have a hunt for 'A2DP' in the Hardware troubles Forum and you'll see my old thread:

They work and have really great stereo sound provided the BT stack is updated with the A2DP profile. Unfortunately the buttons still don't work with the Axim, even after this hack. I know they work with my desktop because I bought the BlueTake dongle and tried them out.
And the volume when using my Axim doesn't go below a certain level although it can go up and down using the built-in volume control provided you stay above this level.
On the upside they're great for street use. On the downside they eat up the poor old standard battery in less than a hour.
