Hello again guys, i''m currently looking for a new pair of headphones as my old hyperx have just died. I'm currently looking at the sennheiser g4me ones,(£150), or the Sennheiser 373d, (£200.) I would be using the game ones plugged directly into my motherboard, (asus z170a) compared to the 373ds usb soundcard. The 373d also come with the "dolby surround sound" which i'm not really sure about honestly. I was looking for some insight into which headset would be best. Thanks abunch!
