multiple bluetooth audio pairing

Using Arduino Project Guidance
1

I have the need to connect four bluetooth headsets together. I was wondering if it was possible to use a Arduino bluetooth module as a master and off the shelf cellphone headsets as slaves. Each headset would connect to the Arduino bluetooth module. Audio would them be broadcast to all four headsets at the same time either from one of the headset mic's or from a different source. I was also thinking of adding an interface where the audio output could be started or stoped as needed too.

Is this a feasible project?

I am very new to Arduino so please forgive my vagueness.

It's not really an Arduino question.

Bluetooth doesn't normally connect more than one headset to a phone. It may be possible for a Bluetooth device to connect to more than one at the same time, but I've never seen it done. It would depend entirely on the capabilities of the Bluetooth module, not the Arduino.
