So I got brand new DT 770 PRO 80 Ohm headphones coming from Corsair void pro wireless ones...The problem is I think they are too quiet,for example when I played a game on corsair ones I had the volume on around 30 and on these I have to have it at around 60...I read 80 Ohm are much more powerful and also louder so that's why I'm questioning myself if I need an amplifier or something...
