Verdict
Choose the DT 770 Pro if your workflow demands isolation and prevents audio leakage into microphones. Select the DT 990 Pro if you require an open soundstage for accurate mixing and mastering decisions. Both models share the same high impedance and build quality, so your choice depends entirely on the acoustic environment.
DT 770 Pro vs DT 990 Pro Specs
Back Design
Edge: Tie
The DT 770 Pro Studio uses a closed-back design, which provides passive shielding and isolation. This keeps headphone sound from bleeding into your microphone, making it ideal for vocal booths, drum recording, or loud rooms. The DT 990 Pro 250 features an open-back design. This allows for a wide, natural stereo image, helping you hear placement and depth accurately. This is preferred for mixing and mastering where honest translation is key. The choice depends on whether you need isolation or spatial accuracy.
Impedance
Edge: Tie
Both headphones share an identical 250-ohm impedance. This studio-grade specification means neither model can drive itself to full volume from a standard smartphone or laptop headphone jack. You must pair either the DT 770 Pro Studio or the DT 990 Pro 250 with a dedicated headphone amplifier or an audio interface to achieve their intended performance. This shared requirement ensures consistent power needs and tonal character potential, placing the burden of amplification on your external gear rather than the headphones themselves.
Weight
Edge: beyerdynamic DT 990 Pro 250 Ohm
The DT 770 Pro Studio weighs 9.5 ounces. The DT 990 Pro 250 is slightly lighter at 8.8 ounces. This difference of 0.7 ounces may be noticeable during very long mixing sessions or recording takes. The lighter weight of the open-back model might reduce fatigue for some users. However, both models utilize a spring-steel headband and replaceable velour ear pads designed for comfort during extended use. The weight difference is minor, but the lighter build of the DT 990 could be a small advantage for marathon sessions.
Dimensions
Edge: Beyerdynamic DT 770 Pro Studio Headphones
The DT 770 Pro Studio measures 8.5 inches in height, 7 inches in length, and 4 inches in width. The DT 990 Pro 250 is slightly larger, measuring 9.1 inches in height, 8.7 inches in length, and 4.7 inches in width. The DT 990 Pro has a wider and taller frame, likely to accommodate its open-back acoustic structure. These physical differences affect how they fit in bags or on desks. The DT 770 is more compact, which might be preferable for tighter storage spaces or mobile studio setups where footprint matters.
Cable
Edge: Tie
Both models come with a fixed 3-meter coiled cable and include a 1/4-inch adapter. This means you get the same cable length and connector type out of the box. The coiled design allows for some stretch, which is convenient in a studio environment. Since the cable is fixed on both units, you cannot swap cables between them if one breaks. The inclusion of the adapter ensures compatibility with professional audio interfaces and amplifiers. This shared feature simplifies the initial setup for both headphones, requiring no additional purchases for basic connectivity.

Frequently asked questions
Can I use these headphones without an amplifier?
No. Both models have a 250-ohm impedance. This high resistance requires significant power to drive the drivers. You need a dedicated headphone amplifier or a professional audio interface to reach full volume. Using them with standard consumer devices will result in low volume and poor dynamic range.
Which model is better for tracking vocals?
The DT 770 Pro Studio is the better choice. It features a closed-back design that provides passive isolation. This prevents headphone sound from leaking into your studio microphone. The DT 990 Pro has an open-back design, which allows sound to escape and bleed into nearby mics during recording sessions.
Do these headphones have a wide soundstage?
The DT 990 Pro 250 Ohm offers a wider soundstage. Its open-back design allows sound to project outward, creating a spacious acoustic environment. This makes it ideal for mixing and mastering. The DT 770 Pro Studio is closed-back, which focuses the sound inward for better isolation but a narrower perceived stage.
What is the weight difference between the two models?
The DT 770 Pro Studio weighs 9.5 ounces. The DT 990 Pro 250 Ohm is lighter at 8.8 ounces. The difference is 0.7 ounces. This slight weight variation may affect long-term comfort during extended mixing sessions, though both designs prioritize studio durability over extreme lightness.
Are the ear pads replaceable on these headphones?
Yes. Both the DT 770 Pro Studio and the DT 990 Pro 250 Ohm feature replaceable velour ear pads. This design allows you to maintain hygiene and comfort over time. You can purchase replacement pads separately when the original ones show signs of wear or degradation from regular studio use.
Which model is better for mixing in a quiet room?
The DT 990 Pro 250 Ohm is better for mixing. Its open-back design provides accurate monitoring with a wide soundstage. This helps you hear spatial details in your mix. The DT 770 Pro Studio is designed for tracking, where isolation is more critical than spatial accuracy. Use the DT 990 for final mix decisions.
What colors are available for these models?
Both the DT 770 Pro Studio and the DT 990 Pro 250 Ohm are available in gray. The DT 770 Pro Studio is listed as gray. The DT 990 Pro 250 Ohm is also listed as gray. This neutral color scheme is common in professional studio environments to maintain a consistent aesthetic.
