Vintage Telephonics Headphones Used. They do reproduce sound on both channels, however a good amplifier is needed, my guess is this are high ohm headphones.

If you have any questions please ask before bidding or buying. Stand not for sale, not included. International buyers are responsible for any importing charges.
