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.
- Sturdy and durable build.
- Great, open audio reproduction.
- Stable and well-padded.
- Loud leakage.
- No isolation from ambient noise.
- Slightly tight on the head.
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.
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.
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.

The DT 990 Pro have an excellent sound that's well-balanced, open and spacious and has very low harmonic distortion. They pack enough of a punch to please fans of bass. Instruments and vocals are nice and crisp but lack a little clarity on some tracks. However, the high frequencies of the treble range are a bit too pronounced, at times, and can sound a little sharp for some.
Excellent Bass Range performance. The low-frequency extension of 25Hz is excellent for an open dynamic design. Additionally, the small overemphasis in bass and high-bass adds some extra warmth to the sound.
Very good Mid Range performance. The response is unremarkable for the most part, except for the general 5dB tilt favoring the lower frequencies. This pushes the vocals/leads slightly to the back of the mix and puts more emphasis on the Bass Range.
Average Treble Range performance. Low-treble is underemphasized by about 3dB which negatively affects the clarity and presence of vocals/leads. This shows that the general tonal quality of these headphones is on the dark side. The 10dB bump, although quite narrow, could make the sibilant tones too harsh for some.

Good soundstage. Decent HRTF performance which is responsible creating a soundstage that is perceived as natural and outside of the listener's head as opposed to inside. Also, these headphones sound very open, which adds to the spaciousness and helps the music feel connected to the environment.
Very good performance. The overall amount of harmonic distortion is very low, especially at 90dB SPL. At 100dB SPL, there is a general rise in the amount harmonic distortion, but it remains within good values.
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.
Poor isolaton. Due to their open-back design, these headphones don't offer any isolation below 1KHz. Above 1KHz, there is a 4dB/Octave roll-off present, which will have a minimal impact of blocking outside noise.
Poor leakage. Although the profile of the leakage is quite broad, wider than K702, the general level is lower than most open headphones we have measured. Yet, these headphones still qualify as very open and not suitable where privacy is needed.
