Hi, i recently bought LG V30 and use it with my HyperX Cloud II headset. Ive been listening to music on headphones for over a decade now so id say im not completely deaf in terms of sound quality. Those are my best headphones so far and i wanted to really enjoy that quad dac that comes with the phone. I was thinking something around HD650 price point. Is it big difference when upgrading from 80 ohm to 250+ ohm headphones? I know the sennheisers also have better frequency range but im more interested in impendance since the frequency seems like much less drastic change. But sadly i dont have any chance to try them on anywhere nearby and ive never listened to better headphones then those HyperXs. If you have similar experience or smthg please if you could help me out. If you know about closed isolated ones so i could listen to them at work or in public that would be awesome. Oh and it would be for music and maybe casual gaming. Thanks! FYI yes the phone is able to run up to 600 ohm heaphones. HD650 are apperantly really great from what i heard.
