The Neumann 508821 is the official factory-replacement coiled cable assembly designed specifically for the Neumann NDH 20 closed-back studio headphones. Built to meet the rigorous demands of professional recording environments, this cable offers the perfect balance of flexibility, durability, and high-fidelity signal transmission. The spiral design is the industry standard for tracking and monitoring, ensuring that the cable remains compact and out of the way when not in use.

Product Description

• Dynamic Spiral Design: The coiled (spiral) construction is engineered for maximum versatility. It stays short and tidy when you are close to your audio interface or mixer but expands easily when you need to move around the studio, preventing the cable from tangling underfoot or getting caught in chair wheels.

• Secure Twist-Lock Connection: Like all genuine NDH accessories, the headphone-side termination features the proprietary 2.5 mm twist-lock connector. This specialized mechanism locks the cable into the NDH 20 ear cup, ensuring it won't pull out during intense sessions or sudden movements.

• Premium Signal Clarity: Despite its flexible nature, the 508821 cable is built with high-grade internal shielding and conductors. It is designed to preserve the NDH 20's signature linear frequency response and exceptional isolation, ensuring no loss in audio quality across the expanded length.

• Integrated Threaded Adapter: The cable terminates in a high-quality 3.5 mm (1/8") mini-jack and includes the official 6.3 mm (1/4") screw-on adapter. The threaded connection ensures a rock-solid link to professional mixing consoles and headphone amps, eliminating the risk of crackle or signal dropouts.

• Built for Longevity: The heavy-duty outer jacket is designed to withstand constant stretching and retraction without losing its shape ("memory"). It is also treated to reduce microphonics, ensuring that cable movement doesn't introduce unwanted noise into your listening experience.
