Such a well made headphone. Industrial design solid. And they look so good. Exceptional for use and any abuse in the studio.

Austrian engineering from the well respected AKG brand.

Detachable cable, Two supplied—straight and coiled.

Read about them on-line as this model has been around for a long time.

Closed back, noise isolating. True playback, crisp mids, close to the Harman target ideal. Accurate bass. Clear non-fatiguing treble.

One owner in a smoke and pet free environment.

Folds flat for storage and or transport.

Little used. No signs of use. Used for hi-fi listening and not in the studio. Worked just fine for me in that capacity. Need to pair down collection. No scratches, dings, or abrasion. Pads look pristine. Seller  lives in a small apartment where storage is a premium so boxes are often tossed...or often gets squished. This box is a 7 out of 10, I would say.
