DT 770 vs DT 990 Key Specs
Back Design
Edge: Tie
The Beyerdynamic DT 770 Pro Studio uses a closed-back design. This provides passive shielding and isolation, keeping headphone bleed out of your microphone. It is ideal for vocal booths, drums, and loud rooms. The Beyerdynamic DT 990 PRO features an open-back stereo construction. This design delivers a natural soundstage and detailed spatial imaging. It reveals subtle nuances in audio, making it perfect for professional editing, mixing, and mastering. The open design allows sound to pass through, creating a wider, more natural listening experience compared to the isolated sound of the closed-back model.
Impedance
Edge: beyerdynamic DT 990 PRO 80 Ohm
Impedance determines how much power the headphones need. The DT 770 Pro Studio listed here has a 250-ohm impedance. This high impedance needs a headphone amp or audio interface for full volume. It is not suitable for phones. The DT 990 PRO in this comparison has an 80-ohm impedance. This versatile impedance is ideal for a wide range of applications, from professional studio outputs to high-fidelity home audio setups. It ensures distortion-free audio reproduction with superior sound fidelity. The 80-ohm version is easier to drive than the 250-ohm DT 770 Pro, requiring less powerful equipment.
Cable
Edge: Tie
The included cables differ significantly between the two models. The DT 770 Pro Studio comes with a fixed 3-meter coiled cable. This coiled design is common in studio environments, allowing the cable to stretch and retract. It also includes a 1/4-inch adapter. The DT 990 PRO features an extended 3-meter straight cable. This straight cable design offers more freedom of movement without the potential tangling of a coiled wire. It also includes a threaded 1/4-inch adapter for 1/8-inch jacks. The straight cable may be more practical for some users who prefer a non-retracting wire.
Weight
Edge: Tie
Weight affects comfort during long listening sessions. Both headphones weigh exactly 9.5 ounces. This identical weight means neither model has a physical advantage in terms of heaviness. The DT 770 Pro Studio features a spring-steel headband and velour ear pads. The DT 990 PRO has soft, replaceable circumaural ear pads and lightweight construction. Both designs aim to provide luxurious comfort for extended use without fatigue. Since the weight is the same, your choice will depend on the headband feel and ear pad material rather than mass.
Dimensions
Edge: Beyerdynamic DT 770 Pro Studio Headphones
Physical size can impact portability and storage. The DT 770 Pro Studio measures 4 inches in width, 8.5 inches in height, and 7 inches in length. The DT 990 PRO is slightly larger, measuring 4.7 inches in width, 9.1 inches in height, and 8.7 inches in length. The DT 990 PRO is wider and taller than the DT 770 Pro Studio. This difference may affect how they fit in bags or on desks. The DT 770 Pro Studio has a more compact footprint, which might be preferable for users with limited space.
