Beyerdynamic DT1990 pro headphones

The DT 1990 Pro headphones have much in common with the previously released closed-back model DT 1770 Pro: they are characterized by an equally reliable design, many of whose elements are replaceable, and are equipped with highly efficient drivers made using exclusive Tesla technology and providing "flawless sound with excellent resolution." Among other advantages of the new model, the developer names modern design, manual assembly, a durable adjustable headband made of spring steel and soft, replaceable ear pads that provide optimal comfort during use. The new product comes complete with two cables (3-meter straight and 5-meter, twisted into a spiral), which connect to the headphone cup via a mini-XLR connector, a hard transport case with a zipper, and an adapter from minijack to jack. In addition, the DT 1990 Pro comes with two pairs of velor ear pads with different sound characteristics. Using one pair of headphones provides a neutral, analytical sound, while using the other pair provides a warmer sound with more bass.
