Designed for editing, mixing, and critical listening, the Neumann NDH 30 Headphones offer a calibrated studio loudspeaker setup in the form of a portable headphone. The open-back circumaural fit construction ensures reference-class sound with maximum comfort. The headphones make use of 38mm drivers, which work as acoustic dipoles, allowing for highly refined sound characteristics to unfold optimally. One can expect an extremely fast transient response, dry bass, uncolored mids, and transparent highs. In other words, the NDH 30 are devoid of distortion and coloration. They provide a frequency response of 12 Hz to 34 kHz. The NDH 30's high-quality construction of spring steel and aluminum ensure tight tolerances for consistency. The headphones are foldable, which help while on-the-go. The NDH 30 includes a detachable, internally balanced cable that's designed to minimize crosstalk while increasing spatial resolution. The NDH 30 includes a 1/4" adapter and a soft cloth carrying pouch.
