You’re most likely familiar with the name Beyerdynamic as they are a highly trusted audio brand putting out a wide range of premium products loved by professionals worldwide. The DT 990 PRO are the open-back model of their DT PRO series which comes in a selection of 32, 250, and 600 ohm impedance levels to suit your mode of playback. They are designed for studio applications and fulfill the critical listening requirements of engineers working in post-production.

The first quality repeatedly attributed to the DT 990 Pro is their immaculate 3D-like sound stage which allows for pinpoint placement of elements within a mix, and an immersive listening experience. Surgical mixing and stereo imaging are truly made simple.

Their second most touted quality would be their crisp highs which have a few peaks and valleys between 8k and 20k. Some people claim these frequencies are too bright, and perhaps for very loud recreational listening that could be true. But for mixing purposes we find them to be more revealing than shrill. The DT 990 Pro don’t hype any frequencies and the lows and mids are certainly rich so this lift in the highs does not at all feel isolated or divorced from the rest. Again, another reason why we highly recommend them for sound sculpting applications.

The DT 990 Pro definitely have an authoritative low end with a wide Q peak between about 100 to 250 Hz, enough to add an intelligent amount of punchiness without blinding the engineer with unbiased “boom.” Their hand-made neodymium drivers offer a frequency response of 5 – 35k Hz to let you work effectively from everywhere within the range of human hearing and with extremely low harmonic distortion.

In terms of build, The DT 990 Pro are as sturdy and comfortable as they look. Though their ear cups are large with a lot of velour padding, they are surprisingly very light and comfortable to wear for hours without applying too much pressure or getting too hot. They are durable for years of use while also being easily serviceable as all of the parts are replaceable. The curled cable is quite long (3m) in length but is unfortunately not detachable.

It’s great that Beyerdynamic has made the DT 990 Pro available in different impedance levels, this is something worth considering when choosing studio monitor headphones. Like we’ve mentioned, these are headphones for the studio professional working predominantly in post-production. For open-back headphones they manage to keep a lot of volume inside but they’re maybe not the best for tracking drums or guitars. But for sound design? They’re a steal. If you like the sounds of the DT 990 Pro but are looking for closed-back, try the DT 880 Pro or DT 770 Pro which offer similar characteristics but some flatter frequency response in a closed design.
