Yamaha YH-5M Orthodynamic Headphones with Cable, Case, and Box Here's your chance to own a rare piece of audio history with the Yamaha YH-5M Orthodynamic headphones, a Japan-exclusive model from 1978. These headphones feature Yamaha's iconic "Orthodynamic" drivers, using a planar-magnetic (isodynamic or magnetostatic) design that combines the best of dynamic and electrostatic technologies, delivering a precise and immersive sound experience.The YH-5M boasts an impressive efficiency rating of 113dB and low impedance of 20 ohms, making them incredibly easy to drive, even with low-powered devices. However, like modern IEMs, they are also highly sensitive to noise, capturing every detail of your music.One of the YH-5M's unique features is its convertible design, allowing the user to switch between open and closed-back configurations by attaching or removing the cone-shaped "back-cavity" covers. When the back-cavity is attached, you enjoy great noise isolation in a closed-back design. Removing the covers opens up the sound, offering a clearer, more open listening experience.The design of the YH-5M was inspired by headsets used by pilots and broadcast monitors, combining functionality with superior sound engineering. The headphones are a brilliant fusion of full-size headphone comfort with the compact sound sensitivity of in-ear monitors.These lightly used headphones come with the original cable, case, and box, making them an exceptional find for collectors and audiophiles alike.
