This is for two (2) sets of noise concealing 8-ohm headset.  These are commercial quality monoral headsets. Made by Communication Industries out of Grafton Vermont.  These are generally used for testing student which are plugged in to a computer or other mono audio source.  These have a loose curly-cord with a 1/4 inch phone plug.  These are great quality and when the cushioned muff is properly secured your ancillary ambient noise is vastly reduced.  I have 30 of these I will deal on a quantity of them.

Flat-rate shipping for the two (2)  $10.50
