I mainly use these headphones for playing games with immersion and watching movies and it's been incredible so far.
The impedance is low, so I could connect to my pc, laptop and phone with no problem whatsoever. (although you can definitely hear the difference between the different DACs)
The clamping force is less than beyer's other, more studio oriented headphones and it just disappears on my head after a few minutes, so comfort is top-notch for me.
My only complaint is that the cable isn't detachable, which could be a problem if someone isn't careful.
After 2 years of daily use the leatherette covering of the headband has started to peel off slightly, but it's nothing significant.
Overall I'm quite happy with this purchase!
