hey guys i bought a sennheiser hd558 a couple of months ago and they are too open.. i am looking for a new headset. i see nowdays alot is USB. i am used to 3.5mm plug. what are benefits of USB? it has integrated sounddevice? also im used to 2.0 and theres also alot of 5.1 and 7.1 out there combined with usb. does 7.1 benefit me in quake?

just want to know what the best closed headsets are at this moment under or up to 200 euro and particular for quake

im thinking about:

Steelseries Siberia 650 Headset

Steelseries Siberia Elite

Steelseries 9H or Razer Blackshark

also heard studio headphones as audio technica ath-m50x and m40x are very good

thank you
