Hi all,I bought Beyerdynamic DT770 Pro Headphones the other day to use with my PS4 via connecting through the jack in the headphones. I am reading a lot of conflicting advice. Some say that it should work fine, others are saying I also need an amp to power the 80 OHM version. I really don't want to spend more money or clutter my sitting room up with more stuff. Could anyone here more knowledgeable than I advise?
