I need away to use my blue tooth ear piece as a transmitter to another blue tooth ear piece.

I need to be able to listen from a short distance away. sort of a spy device.  having its own coded freq. would be helpful too.

You're not going to be able to pair one headset to another, but you may be able to pair two headsets to the the same device (a phone, I assume?) if the device supports multiple pairing. Refer to the operator's instructions for pairing the headsets. It may be as simple as just doing the pairing procedure twice.
