I've tried tweaking the custom settings and I've gotten music to sound much better but I think more visits to the audiologist are in order to really squeeze all I can out of these. I have nice detail in the highs I was missing but on the custom setting if there are any ambient room noises (even from adjacent rooms) it's WAY over amplified. Like my dogs nails on the hardwood hallway floors sound like jackhammers. It's only certain sounds though. I had to get a new office chair because every little movement made a creaking sound that was explosive in my ears. Even the sound of door handles clicking shut are deafening. Weird.
