Why Roccat? Why Kave?
No real reason why I bought it but if you want one then its the real 5.1 it offers. Attracted me by 1st sight. So I asked 3 dealers(moderno, Cex and lingloong) for their price and simultaneously placed an order for 2 units, one for me another for a friend. That's about 24 hours ago. So Cex informed me that stock's ready for my collection yesterday night but due to lack of transport, I collected them this evening. Unboxed it nice and slowly. Finally got them on my head and ears, the feeling was great as opposed to Siberia and Piranha, they really cause pain. I compared these 3 headsets side by side and found the Kave best amongst them, the bass is not as heavy as the Piranha but much better compared to Siberia. The Siberia somehow lacked the crisp supposing present in some audio. For audio clarity, I guess the Piranha would take champion but its really hard to distinguish which is better comparing with the Kave unless you're looping the same audio again and again to catch every note. The Kave's rear speakers are not as distinct as the front so I suggest have the rear's volume higher than front. However, the Kave weights quite a lot. Apparently, the Siberia is found to be the lightest amongst the three while the Kave's heaviest.
