Plantronics-SupraPlus-HSeries-Monaural-NC-NoiseCancelling-Federal-FAA-Telephone-Headset

Plantronics manufactured a special H-series headset for the Federal Government. They were often used by the FAA when it is important to only hear one voice on the line (not a lot of background noise). Thankfully, Plantronics used the same connections they use in their consumer grade equipment. For best results, you need to have this mic right in front of your lips, almost eating it, but you get zero background noise! Comes in a plain, white box.
