Beyerdynamic DT 990 Pro Says Open is Better, While DT 770 Pro Disagrees

While both of these headphones are audiophile-grade quality, there’s much debate over which is better. The only way to find out if less is more was to test them. So that’s what we did.

What We Were Looking For

If you’re intent on listening to professional-quality audio on your computer or mixer, you can’t do without the likes of an accurate-sounding pair of headphones. We wanted to know:

  • If the DT 770 Pro sounded better then the DT 990 Pro.
  • If the DT 770 Pro really is ideal for sound monitoring.
  • Whether the DT 770 Pro justifies its significantly higher price point.
  • Whether being open back serves any purpose for the DT 990 Pro.

The Specs

First let’s breakdown the technical info for both Beyerdynamic headphones.

Common Features 1: 5Hz – 35 kHz

You could easily spend the entire day reading conflicting opinions about whether or not 44kHz resolution is better than, say, 35 Hz.

Both Beyerdynamic DT 770 and DT 990 pro offer 5Hz- 35 kHz A/D resolution. For the best combo, we recommend pairing with a good-quality audio interface.

DT 770 PRO

In truth, only the most rabid audiophile would be able to tell the difference.

Closed-back design, 5Hz – 35 kHz, 250 oms. 45 mm driver, weighs 8.8 oz.
Excellent value for the money, top tier sound separation, Clearly hear every instrument in your mix and their position.

DT 990 PRO

Because both devices are products of Beyerdynamic, you won’t find any difference between them when it comes to how they process the 5 – 35 kHz frequency.

Unless your intended audience is dogs or maybe bats, no one is likely to notice the difference.

Common Features 2: 45 mm driver

Both headphones offer a 250-ohm impedance and 45mm drivers for excellent crisp sound.

DT 770 PRO

With the DT 770, pro direct monitoring has a much more clearly defined purpose. After all, if there are multiple instruments playing and singers singing, things can get confusing.
Being able to monitor everything in what is essentially real-time with any extraneous sounds eliminated can be valuable.

DT 990 PRO

The differences in sound with the DT 990 pro are very close to the DT 770 pro, but it’s slightly just a little different. The 990 is considered an open back set of cans which means the sound output is a more spacious open world sound, closer to stereo speaker sound.

Winner: DT 770 Pro

Why? Only because the value of direct monitoring is harder to quantify when it comes to a single guitar/singer than it is with multiple musicians jacked in at once.

Unique Features: DT 770 PRO

 Sound Isolation

The Beyerdynamic DT 770 pro offers more sound isolation than the DT 990 pro; its strong suit is proper monitoring.

Unique Features: DT 990 PRO

Open world sound

The DT 990 Pro offers an available set of cans meaning the sound reproduction is more open. Popular with gamers of first-person shooters like call of duty, Fortnite, and apex legends. You can quickly pinpoint enemy footsteps and identify all sounds in the world.

Lower price

The price difference on the DT 990 pro vs. the DT 970 pro is not a deal-breaker for most, but currently, the DT990 is more economical.

Winner: DT 990 Pro

Why? It costs less, and most people wont hear the difference.

Final Verdict

But, if we assume that coughing up the extra few bucks isn’t going to be an issue, then we have to come down on the side of the DT 770 pro.

Not only is it on par with the DT990 Pro when it comes to delivering crisp sound, but it adds an extra layer of versatility without any loss of quality that puts it over the top.
