Question about Beyerdynamic DT 990Pro

as it's been told the impedance is high for PC. anyway it gives you a sound but not too loud. At macbook pro or intel nucs it is enough to listen to the music.

No, the headphones are 250 ohms, so your sound card needs enough juice to drive the headphones. Most onboard sound cards do not have the necessary resources. I use an external sound card from Creative in my company.

You can plug it in without any problem if you have a jack on your computer.
