I use it with a Steinberg UR22 sound card. The sound is too quiet. For example, when used for everyday listening through a computer (music, video), the sound level in Windows is about 70%. If you do 100, the sound is loud, but not such that you can't stand it directly. There is a topic on the Steinberg forum where the owners of such headphones and UR22 cards write that everyone has such a problem. Ideally, you need an external amplifier. And another point (this is not a drawback): there are gaming microphones that make these headphones a full-fledged gaming headset. So, do not buy such microphones with a 3.5mm jack, because. at the headphone input there is a 2.5mm jack plus a locking system that prevents the wire from falling out.
