I am running a Asus laptop x7515 connected to a Samson Expedition 150 PA. The lap top has Bluetooth and what I want to do is get some sort of monitor/mic. Can I use a Bluetooth headset like this-

I could eliminate a microphone and stand I had planned to get for introducing my songs. The ear piece could be my monitor as well ?
