I hate Razer's headphones. They're cheaply made and come with some pointless software that I'm forced to use. I’ve bought two pairs from Razer: the original Krakens and the Blackshark V2 Pro. The Krakens' headband broke after just 6 months, even though my head is pretty normal-sized.
Now, with the Blackshark V2 Pro, after 8 months, the leather on the headband has almost completely peeled off, leaving behind this ugly yellow sponge. After about a year and a half, the volume knob became super wonky. I have to position it just right to hear from both speakers, and if I lower the volume too much, the right speaker cuts out completely.
I even tried disassembling it to clean the volume control, but it didn’t help. I'm done with Razer. Never buying anything from them again.
