Plantronics H251N

SupraPlus Noise Canceling is a new version of the old Supra Noise Canceling.  The Plus has a fixed boom which is much easier to position correctly.  Most of the problems with the old black Supra NC's revolved around the 'flexible' boom 'popping' out of the capsule and hanging by its' wires.  Because the boom was flexible the microphone got out of postion all the time.

 

The H251N is a much better headset.
