Beyerdynamic DT 990 Pro

Open headphones with legendary sound

In a nutshell

The Beyerdynamic DT 990 Pro is a classic and will likely remain so for an indefinite period of time. Because a lot of things fit together very well, it would be a shame to limit its areas of application to the studio. Indeed, the DT 990 Pro also has its place in the hi-fi arena. As a good all-rounder, it can match if not beat much of the competition in a wide variety of disciplines, including impulse reproduction. In short, highly recommended!


With the DT series headphones, Beyerdynamic developed a benchmark in the field of analytical music listening at the beginning of the 1980s. Since then, the DT-990 has established itself in professional use and is considered a permanent fixture in the studio.

While most models in the DT series are clearly aimed at the studio sector, the 990 Pro has the potential to convince even die-hard hi-fi enthusiasts. On the one hand, this is due to the very pleasant ear- and head-wearing comfort experienced by a listener; on the other hand, the 990 Pro offers such a tidy and fine sound that listening to music is simply fun, no matter whether in the studio or at home.

Optics and haptics

The DT 990 Pro is something like a blueprint for generations of headphones to come, whether from Beyerdynamic or for optically and functionally similar models from other manufacturers. The earcups are padded with velour and flatter the ears, while the stable-yet-easily-adjustable headband is completely encased and therefore very comfortable to wear. The open construction of the 990 Pro reinforces the impression of an airy, lightweight headphone that is not burdensome, no matter how long you wear it. At the same time, you never have the feeling of being cut off from the world due to the somewhat moderate outside attenuation. This makes these headphones the first choice in the control room or in the home studio, but not really for use in the recording room where the damping would have to be better to really judge the notes. Their use in front of the microphone only makes sense where crosstalk is not an issue. Otherwise, you should see the DT 990 Pro behind the scenes rather than at the forefront of the action.

Sound properties and image

The DT 990 Pro has not become a classic just because of its workmanship and construction, but also because of its sound. This is due to the dynamic, extremely light diaphragms, which provide an enormously balanced, beautiful reproduction across the entire spectrum. The 990 Pro sounds really good throughout and offers practically no overemphasis or break-ins in the audible range. The spatial staggering and imaging are correspondingly good, allowing a reliable assessment of the acoustic details as well as aesthetic beauty. It is therefore easy to understand that many users really rely on this handset when it comes to the final assessment of their mix.



As mentioned, the DT 990 Pro has its special strengths when used in the control room. For musicians who want to record an instrument, it is only a good choice if the ambient noise is kept within reasonable limits – it is certainly not possible to record in the same room with a drumset. Even listening to your own amp in the recording room becomes rather difficult, but if you are in the control room while the amp next door is roaring, you will certainly like the DT 990 Pro.
For singers and speakers, in particular, these headphones are a good choice. Although a technician may have to work with the volume of the backing – in practice – vocal musicians will feel particularly comfortable with the DT 990 Pro.
