Offered here are these David Clark Company Inc. Noise Canceling Headphones with Microphone, Model H10-60. The headphones are used, but are in good, working condition. They are corded connection and have a p/n number of 12507G-31. They have an adjustable headband, and a microphone that pivots up and down. The little foam cover on the microphone is worn and crumbling. It will need to be replaced. I am unsure of the exact age of these headphones. They are made for use in airplanes and helicopters to communicate over the noise of the aircraft. They are one size fits most and will fit virtually any adult. They have padded ear cuffs. They are a little dusty and will need to be cleaned up a bit. They are a great pair of used noise canceling aircraft headphones. David Clark Co. Inc.
