The Neumann NDH 20 are closed-back headphones that combine excellent isolation with the carefully balanced sound image and exceptional resolution you expect from a Neumann product. The NDH 20 is therefore ideally suited for monitoring and mixing tasks, even in loud and noisy environments. Circumaural memory foam ear cushions provide high long-term comfort. While many other closed-back headphones are marred by unpleasant midband resonances that make it difficult to make reliable mixing decisions, the NDH 20 delivers a surprisingly detailed and well-balanced sonic image, similar to acclaimed studio speakers from Neumann. Superior sounds along with large memory foam ear cushions make the NDH 20 a pleasure to wear for long periods without fatigue. The NDH 20 uses newly designed drivers (38mm / 1.5") with high-gauss neodymium magnets to ensure high sensitivity and minimized distortion, allowing the user to listen to the pure audio signal without unwanted coloring.The mechanical construction also meets the highest standards.The adjustable headband is made of flexible steel while the ear cup covers are machined from lightweight aluminum.For easy transport, the headphones are foldable and can be placed in the supplied soft cloth bag.Two detachable cables (one straight, one coiled) and a 6.3mm (1/4") adapter are also included.
