The Neumann NDH 20 is a closed-back, circumaural studio headphone that combines strong isolation with the balanced, detailed sound Neumann is known for. It is suited to tracking and monitoring for musicians and engineers, front-of-house work, and mixing on the road where outside noise is a problem, and it isolates by more than 34 dB above 4 kHz so little sound leaks out to nearby microphones. The 38 mm dynamic drivers with high-gauss neodymium magnets deliver a wide 5 Hz to 30 kHz response with low distortion, and large memory-foam earpads keep it comfortable over long sessions. Construction is a flexible steel headband with machined aluminium ear cups, and it folds flat for transport. Impedance is 150 ohms, sensitivity 114 dB SPL and weight 390 g without cable. This silver version (catalogue 508585, silver/anthracite with orange accents) ships with a straight cable, a coiled cable, a 6.3 mm adapter, cloth pouch and guides.
