This is a very nice pair of extremely rare, vintage Audiotronic AHP66 Audiophile Flat Drive Orthodynamic Headphones. The headphones are in excellent condition with minimal signs of wear. They are super clean and in amazing shape overall. These are very similar to the Akai ASE-50 headphones in their design and drivers. These headphones sound phenomenal with superb detail and great clarity. I put perforated memory foam earpads on them with improve the sound and the comfort. Included is a carrying case along with the original earpads. These are perfect for any audiophile or collector!
