Bluetooth as a PC mike?

I lost my Bluetooth phone (actually, I put it in a McDonald's bag for "safe-keeping" at a beach known for car theft and neglected to mention to Tina that she shouldn't toss the bag in the garbage). I have a Jabra bluetooth headset which works(-ed) great and I thought I'd use it as a mike for making notes on my Tablet, for which I have a USB Bluetooth dongle. But when I "look for devices" from the PC, it doesn't see the headset. Is there a way to use a bluetooth headset for PC input and output?
