    Comments about Koss VC20 Volume Control:

    The input resistance is about 4.5Kohm per channel but I would imagine it would go down to headphone resistance at maximum volume. So it does not overload the walkman, computer, etc. It should have had a built in mic for cell phones so you could use your own headphones. The plug is 3 conductor. I made a device with Radio Shack parts for hearing my cell phone ring when I am listening to my walkman in the headphones and it is currently plugged in to the library computer with the vc20 lowering the volume.
