Hey guys. I’m new to this “audiophily” thing, so i would like to ask for your suggestion. I have beyerdynamic dt770 pro’s (80ohm) + fiio k5 amp for about 6 months and I really like the low end on this headphones. Mids and highs are not that satisfying sometimes. Now i feel like its time to get a new pair of headphones. Any better choice? My budget is 500$.
