Razer Kraken Ultimate: Sound is Muffled when THX Spatial is on

So, I just got a Razer Kraken Ultimate, when I plugged it in, the sound was bad, until I realized, that it was bad, because of the THX spatial audio, that was turned on. The Sound is fine, if it is in Stereo, but when I turn it to Sorround (turn THX on), it suddenly sounds very muffled. I searched throug varrious Threads, in some I found out, this weird sound thing can be Fixed with EQualizer settings, can somebody give me some good EQ settings, so the sound is ok in THX? The one settings I found, fixed the muffled sound, but made the sound sound to sharp and that is kinda hurting my ears.
