I say go with the corsair vengeance 2100 or H2100 (same thing) but h2100 is newer i think. Way better than both, ive had experience with both headsets. The logitech has great sound and is comfortable, but the constuction is very weak, it wont last too long. The Kraken 7.1 has great construction and feels premium, but sound is no good, buzzing in the background alot, and when switching programs, synapse takes a while to sync. For example,, i am talking to my friend on skype, then I want to listen to some music, you wont hear anything for a couple seconds because its syncing.
Hope it helps!, right now, im also looking for a good headset too.
