I have them too. I want to say you could have waited a bit longer and wait for BF since they might drop in price. But still a good headset under 150 dollars. What amp are you using? Since they do require amping to sound good.
The only thing i dont like about its sound quality is its smaller soundstage, compared to the X1 I had. It still sounds better to me compared to the A40s. Positional accuracy in the PC350 is pretty good too, not alot of bass, so that helps alot in terms of clarity in mids and highs. Probably would be an ideal headphone if you go to LAN parties where you need that isolation.
I kind of want to say one of the best headsets out there for a competitive type of headphone. Kingston Hyper X cloud might be a good overall headset, especially for immersion, since alot of reviews indicate they even like it for music.
