A remarkable piece of audio history: a pair of Yamaha HP-50A Orthodynamic headphones, dating back to around 1979. What makes this specific item exceptional is its time-capsule condition. This pair of headphones is in excellent aesthetic and structural shape. The original earpads are beautifully preserved, maintaining their shape and flexibility, and the headband remains completely intact. Key Features & Collector's Value: Legendary Orthodynamic Technology features Yamaha’s pioneering planar-magnetic drivers, famous for their natural, organic midrange and lightning-fast transient response. The headphones are 100% Original & Unmodified. Retains the factory-original 6.3mm MONO jack plug and cable. It has never been cut, modded, or tampered with—a rare find for purists who value historical authenticity. Perfect Modding Candidate or Display Piece, ideal for vintage audio collectors, Yamaha enthusiasts, or audiophiles looking for a pristine base for custom stereo-cabling projects. Technical Condition: Fully functional. Please note that due to the original factory mono plug, these headphones are wired for mono output.
