These arrived this morning. Been using them for a few hours now and I'm not impressed.
Compared to my PC350's the only advantage to the Commander is that it blocks noise from the surrounding environment a little better.
Other than that, it's about on par with sound quality and much less comfortable to wear.
I know that they haven't been "burnt in" for long, but I couldn't imagine wearing them for more than an hour at a time.
Obviously, like with any audio equipment, the experience will be different for everybody, but for me, considering the price, the PC350's are better.
As a side note, the Dolby 7.1 USB sound card is excellent. Emulates 7.1 much better than my Xonar STX.
Great service by Overclockers overall!
