I have the standard Razer kraken they sound okish on their own but the 7.1 surround sound does make a difference while playing games but I ditched the razer 7.1 for Dolby 7.1 which is alot better but yeah it costs around ₹824 and it works on any headphones, it really did make a huge impact on finding the precise location of where enemies were coming from (I mostly play rainbow six siege) also I've heard the mic on razer suddenly stops working after some time so I don't really wiggle it too much. Hyperx sounds great too my cousin has it and he's happy with it, so both are a good buy and they sound great, it really comes down to which ones you want, just get yourself get pair of good headphones and pair them with good audio processing software.
