The Beyerdynamic DT 990 PRO are sturdy critical listening headphones. They deliver an excellent audio reproduction but their open-back design is not ideal for everyday casual use. They will leak a lot, even at low volumes and don't block any ambient noise. They're also a bit tight on the head.

Beyerdynamic DT 990 PRO Design Picture

The DT 990 PRO are sturdy, ruggedly built headphones. They can easily handle a few drops without getting damaged. The ear cups are well padded and fit around most listeners ears comfortably.  They're also surprisingly stable, although, they're not designed for gym use or sports. Sadly, they're a bit bulky and a little tight on your head, which can get uncomfortable during long listening sessions. They also don't offer any audio controls.

Style
Beyerdynamic DT 990 PRO Design Picture 2

The Beyerdynamic DT 990 PRO are decent-looking reference headphones. They have a relatively compact and utilitarian design. However, the materials used in their build gives them a little more flare and high-end appeal. The ear cups are covered in a suede-like fabric. The headband is completely made out of metal and has a stylish and detachable padding cover.

Clamping Force
Show Help
What it is: The force that the headphones exert on your head, once you have them on. This is purely a measurement of the force applied, which does not take into account the earpad's surface area and the resulting pressure you will feel, on or around your ears.
When it matters: The tighter the headphones, the more force they put on your head. This can get uncomfortable or cause pain and soreness during long listening sessions.
:
1.4 lbs

The DT 990 PRO are comfortable headphones but are a bit tight on your head. They have well padded and large ear cups that fit comfortably around most listeners' ears. However, the headband is a little too rigid which make the headphones tight enough to become uncomfortable during long listening sessions.

These headphones are moderately stable on your head. They are not designed for sports and will slip off your ears during high-intensity physical activities or while running. However, the tight fit these headphones provide is more than enough to keep the headphones on your head during casual listening sessions.

The DT 900 PRO are not designed to be highly portable. They're big and bulky and do not fold into a more compact format or have swiveling ear cups that lay flat to take up less storage space. They are on the larger side for over-ear headphones and would only fit in a bag or a big purse.

These headphones have a solid, sturdy build. The headband has a rugged metal frame that can handle a decent amount of physical stress. The open-back ear cups are, unfortunately, made of plastic which makes them less durable compared to the rest of their build, but they are dense enough, to not get damaged from a couple of drops.

8.2 Soundstage
Show Help
What it is: Soundstage qualities are not inherent to the audio content, the headphones have to 'create' them rather than 'reproduce' them. They determine whether the sound is perceived to be coming from inside or in front of the head, how open and spacious the soundstage is, how much the headphones acoustically interact with the environment, and how strong the phantom center is.
When it matters: When an accurately produced, large and spacious soundstage, similar to that of a stereo loudspeaker setup is desired.
PRTF Error
Show Help
What it is: The average amount of deviation in Pinna-Related Transfer Function of the headphones, compared to that of a loudspeaker. Whether the soundstage is perceived to be unnatural, located inside or in front of the head, is dependent on this quality. The more the headphones activate the HRTF resonances of the ear (similar to what loudspeakers do), the more the soundstage will be pulled out from inside the listener's head. This quality affects both stereo and mono content.
When it matters: When a natural, in-the-front soundstage is desired, similar to that of a loudspeaker.
Good value: <5

Openness
Show Help
What it is: How open the headphones are, and how open and spacious they sound. This quality affects both stereo and mono content. This test differentiates between acoustically and electronically produced crosstalk and only takes the acoustically generated crosstalk into account. This value is the inverse of the Noise Isolation test score.

Acoustic Space Excitation
Show Help
What it is: How loud the headphones are, and how much they excite their environment acoustically. If the headphones are loud and open enough, the sound leaking from the headphones takes some of the characteristic of its environment (reflections/reverb) before reflecting back into the open headphones and to the listener's ears. This quality affects both stereo and mono content. This value is the inverse of the Leakage test score.
When it matters: When an open, wide and roomy sound is desired.
Good value: >7.5
Noticeable difference: 0.5

7.4
Correlated Crosstalk
Show Help
What it is: How strong and solid the phantom center is. This is mostly a stereo quality and its effects on mono content are minimal. This test is sensitive to the phase of the crosstalk and whether it is produced acoustically or electronically.
When it matters: When a true reproduction of the stereo image is desired. A value of 0 indicates no crosstalk, or that the existing crosstalk is not correlated enough to affect the phantom center. A negative score means the crosstalk is out of phase with the original signal, resulting in a slightly wider stereo image at the expense of creating a 'hole' at the center of the stereo field. A positive score means the crosstalk is in phase and positively affecting the phantom center.

8.0 Imaging
Show Help
What it is: Imaging qualities are inherent to the audio content, the headphones have to 'reproduce' them rather than 'create' them. They determine how accurately the objects are positioned in the stereo image, and how transparent the imaging is.

Isolation

Score components:

The DT 990 PRO are not designed to isolate listeners. They leak a lot and are supposed to, as it improves their sound quality with a more open and spacious soundstage. Sadly, that means they're not headphones you would casually wear in public because their loud leakage will be distracting to the people around you. They also don't block any ambient noise so they won't fare well in loud environments or on noisy commutes.

I am so happy that you've started reviewing Beyerdynamic Headphones - they have good headphones like the DT770/DT880/Costume pro and so on... Is it possible for you to Review just a few audio players for headphones too? for example Fiio X series - because they are important just as much as headphones right?
We don't have any specific plans to review portable players or amps at the moment. However, we believe that the difference in sound quality between headphones is much more noticeable that the difference between players/amps/DACs. So as long as your player/amp/DAC is of a decent quality, it should be adequate for most situations.

I was leaning towards these headphones for a while, but i have since leaned more towards the 880's. Any chance we can get a DT-880 (pro or premium) review soon?
Thanks for the suggestion. We will add it to the list, but the list keeps growing. So it may takes us some time to get to the DT 880.

When looking at these on Amazon there's 2 different types one is a 250 ohm and the other is a 32 ohm does this different quality? Which type is this review using?
We have tested the 250 Ohm model. We are not 100% sure how the 32 Ohm model would measure, but technically the 32 Ohm should be easier to drive (by smart phones for example), at the expense of increased distortion. However, it is debatable how audible (if at all) the increase in distortion would be.

I currently own a Sennheiser HD 598 and plan to get the Beyerdynamic DT 990 PRO. Just want to know if there is a massive upgrade for this. And would my Fiio E10k be able to drive DT 990 250 ohm?
We don't consider the DT 990 Pro to be a big upgrade over the HD 598. The DT 990 is a bit heavier in bass, but also more sibilant than the 598. So if you care about sound quality, you'd probably get more out of your investment by getting a good software/hardware EQ for your HD 598.
