This is my eBay listing of my lightly used David Clark H-PC headset that comes terminated to 3.5mm plugs but is otherwise the same as the classic one used in the cockpit. This is a great general purpose PC headset with obviously much higher isolation that typical gaming headsets but also fits the part nicely for a home sim. Comes with a storage case and the ear pad covers.
I can take payment on Paypal instead of eBay and would be happy to give a discount in that case. eBay listing has price set at $150 or best offer, including shipping.
