Razer Blackshark V2 X Low Audio in PS4

I just bought this headphones for gaming in ps4. But the sound is so low. When im playing games i need to put everything in max volume (ps4 audio and headphones audio in 100%) to have a decent sound. I also found the sound quite muddy even more when the sound is at lower levels. But when I listen to music for example the sound is extremly high. Is This normal? Does it have the same problems on PC for example? I would like to know if the headphones are somehow broken or if this is normal. Thank you.
