Razer Kraken Pro advantages/disadvantages?

[Eludium]

I'm buying a new headset, Razer Kraken Pro, and I want to know if the difference between it and 7.1 version is REALLY that big. Like, did I make a bad choice choosing this one over a more expensive 7.1 surround one? Except 3DSound, are there any more features 7.1 has and Pro doesn't (and no, the USB port is not a feature, if you ask me, I hate USB and I'm glad that Pro uses the classic wire style)? Also, the Razer Surround program is well known due to creating surround sound. Now, I know that program is definitely not able to make my Kraken Pro sound as good as a 7.1 headset, but will it let me hear in somewhat 360° or not like that? Also, are the bass and microphone as good as expected on this headset, if anyone know? Thanks for answering!
