Long-lasting comfort and accurate performance make the DT 770 PRO the perfect monitoring headphones for recording studios, post-production, or broadcast settings. The low-mass coil and diaphragm assembly produces transient performance rivaled only by electrostatic earphones, and when combined with a carefully tuned frequency response, delivers natural, balanced sound. Soft ear pads and adjustable sliding earpieces, as well as a single-sided connection cable, ensure comfortable listening even during long periods of use. The DT 770 PRO features an 80 ohm driver and a gold-plated 3.5 mm stereo jack plug with a 1/4-inch adapter, making it suitable for use with almost any headphone amplifier.
