Razer Kraken V3X vs V4X i inne

Hi, I'm thinking about buying gaming headphones, I want the best sound quality in a given price range and I came across these two models, V3X and V4X, can someone tell me what the differences are between them? The only thing I noticed is that V4X are USB-C and have an adapter for USB-A and a case XD I tested V3X and I liked them, but I wonder if V4X differ in better sound quality or are they the same in this respect? I would be grateful for all advice and suggestions :)
