Beyerdynamic is commemorating its centennial by introducing the DT 1770 Pro over-ear headphones. This new model, part of the second generation, boasts a closed-back design, while the DT 1990 Pro MKII offers an open-back configuration. Both headphones are equipped with the newly developed TESLA.45 driver, which has been designed and produced at the company's headquarters in Heilbronn.

According to Beyerdynamic, the new driver reduces distortion for a cleaner, sharper response. At the same time, the 30 Ohm impedance ensures easy control. The diaphragm is made of high-quality PEEK polymer, according to the manufacturer, which, together with the other components, produces deep, accurate bass. The coil is made of aluminum-coated copper wire, which refines the highs in particular. Each driver is rigorously tested multiple times during production to ensure consistent, high-quality sound. The specified frequency range is from 5 Hz to 40 kHz.
Both the DT 1770 Pro MKII and DT 1990 Pro MKII are designed for optimum comfort during long nights in the studio or while editing audio at home. The flexible spring steel headband, made from a combination of memory foam and durable leatherette, features a fontanel recess to prevent pressure and discomfort on the top of the head.
Both second-generation headphones come with detachable headbands and ear cups. The DT 1770 Pro MKII comes with leatherette and velour ear pads, while the DT 1990 Pro MKII comes with two different sets of velour. The first is a Producing Velour, which the designers say delivers a fuller, more exciting sound thanks to a slight bass boost. The second is a Mixing & Mastering Velour, which the designers say offers a more analytical sound for making final mixing decisions.
Both headphones come with a hard case for storage and carrying, a three-meter straight cable and a five-meter coiled cable. Both headphones have a suggested retail price of $549 each.
