as first post, i would like to thank you for helping me a lot which pushes me to register in this great forum.
i previously had Audio technica m50, and since 3 years, it is still great.
however, i wanted to have un upgrade for higher level headphone, which lead me after comments on this website to buy the beyerdynamics 990 pro 250 OHM.
today i have received it and i have the following issues:
- Using the FIIO E7 makes it weak and i believe it needs a real headphone amp, please adivse what would be helpful with this headphone.
- I consider the amp this is not issue comparable as this one since i put it on my head, recognized that the left ear has higher volume level than the right one. which made me really worried.
the headphone hasn't burned in yet.
i really need your advise.
