They are not headphones that isolate external sounds due to the pads, and that's why I bought them!
If you only want them for the PC, I don't think it's worth getting the wireless ones, unless you prefer them. They are a bit heavy, but I don't find them tiring because of their construction. Of course, it will also be evident in the summer if the pads, which are fabric, will actually be cooler compared to the "leather" ones that the previous ones had.
I'm not a sound expert, but I have no problem understanding where each sound comes from when I play a game. With iCUE, you can even tune them, although I don't think it's necessary.

Very good headphones but I don't know if they are worth the price of 120 euros. I found them for 80 euros which is a very good value for money. The sound is very good but you will need the Corsair ICUE software and adjust the equalizer, otherwise it doesn't have such good sound.
