For sale rare vintage AKG K340 400 Ohm Electrostatic Dynamic High-End Headphones. Great sounding, especially in high frequency detail. Isolating rugged and sleek headphones.

These headphones shine with a good headphone amp., especially a tube amp they sounded awesome. Probably you need to replace the connectors with a 6.35mm (1/4 inch) or a 3.5mm (1/8 inch) jack (see the last picture the original connectors). I preferred to keep the original connectors.
