The DT 770 PRO is a closed dynamic headphone and has been designed for critical music and sound monitoring. The single sided cable makes the handling of the headphone easy. The cushion system allows the DT 770 PRO to be used comfortably for long periods of time. The sound of the DT 770 PRO is without doubt a benchmark for professional users. It’s secret lies not only in the cutting-edge drivers, which are hand-made in Germany,but also in a very sophisticated bass-reflex system. The membrane can “breathe” in an otherwise closed housing and is therefore extremely quick and precise in its response, accurately reproducing frequencies anywhere between 5 and 35,000 Hz. This makes the DT 770 PRO an ideal tool for critical listening and monitoring purposes. As opposed to many “lifestyle headphones”, the DT 770 PRO is built to last. Only the best material is used, such as neodymium magnets, spring steel headband, anodized aluminum forks, composite housings and soft skin earpads. All of these parts are hand-made in Germany - with incredible attention to detail and quality.
