Review on Beyerdynamic DT 990 PRO Open Studio Headphones - High-Quality Sound for Professionals by Pin Lin ᠌

Ears at 250 ohms. Excellent with quality sound source. Perfectly combined with a stationary headphone amplifier (for example, A20 will open them by 120%). However, you can safely use it both with a smartphone and on a computer. But are they worth the hassle? DSF/FLAC sound just perfect in them. Every eight, every flag, the most insignificant creak of an armchair under a fat booty in the concert hall will be heard. Any musical genre they can do. Bass is just something! Even in games (in modern shooters like BF) they work out with a bang. The twisted wire spoiled the impression a little, which every now and then strives to wrap itself around itself in a knot (the older generation probably remembers a similar one for a telephone handset). If you have to stretch it for a couple of meters, then the left cup tends to come off the ear, so you have to hold the wire with one hand or wrap it around the arm of the chair. All parts of the headphones are interchangeable and can be purchased separately. For especially sophisticated audio maniacs, some companies offer the service of converting this model from unbalanced to balanced. Soundproofing is not very good. With solid equipment, these headphones can be placed next to the workplace or a meter away from it and listen to music without wearing them at all. As for the so-called "warming up", all this is nonsense. Already out of the box they play one hundred percent. Of course, the headphones are not from the budget category. On the street, you can’t just walk around with them, because the cord is too long. Yes, they are not designed for this. Their destiny is a calm comfortable environment at home, when nothing prevents you from enjoying the sound.
