I have the artics 7 and im very pleased.
Varza :
This review wasted me $200. The sound quality is atrocious. My old GameCom 780 (which is less than half the price) has much much better sound. The Arctis has no bass and despite that the sound is still washed out.
They're definitely not bass-heavy, which was something I was looking for. Don't find the sound washed out though - unless I'm trying to listen to music with the DTS-X option turned on, which does make it sound pretty horrible. If that's your problem, you can fix it using the app. Leave it on for the default, but setup a profile with it off, then link it auto-switch for your browser and anyother app you listen to music on.
