Hope this is the right place to post this question. My apologies if it isn't..
I have a pair of beyerdynamic dt770 pro 80 ohms I purchased used. I noticed that the left channel is a bit louder than the right. I confirmed by flipping the headphones around of course, and then by doing a hearing test twice: once with the dt770s and again with a pair of iems. My right ear hearing was better than the left with the iems but significantly lower than the left at a few frequencies with the dt770s
So, I also recently bought a Fiio E17 which fortunately has a balance control. If I set the balance to around +4 right, things sound better. My question is this: is this an acceptable solution to the unbalance in my headphones or am I losing potential sound quality? If not, can they possibly be repaired? I'm definitely a noob but these headphones sound pretty great to me. Im already noticing that my klipsch image S4s that I use at work sound much worse than I ever thought (I used to think they were incredible).
Thanks for any advice. It will be much appreciated.
