Have a set of headphones that I made using ProEars muffs, single volume control, stereo/mono (compatibility switch), heavy duty right angle plug,coiled cord, and 600 ohm speakers. The one ear piece has a small scuff mark, not bad but wanted to let you's know. More than likely could use some black paint or a black marker to cover it, does not affect performance. The 600 ohm speakers produces very good sound. $59.00 shipped.
