Wouldya believe that they used the minilites in the first Star Wars movie when Luke and Han Solo go into the gun turrets on the M. Falcon to shoot at fighters!
Scott, we use the lightweight Plantronic Headsets also. The minilites were phased out in the mid nineties. We get to choose one of three different versions. Either the over the ear, the single sided or double sided headset.
Wouldn't know how much they are as they are issued to us by Airservices Australia. We just get a new one when your headset breaks, and we hand it in when we retire or resign.
