Anyone else notice during the burn in process, from about 40 hours to 65 hours that the bass seems a bit lacking before it comes back up to an acceptable level? Basically did yours go through periods of good sound and bad sound all along during the burn in process? Never had headphones where burn in actually affected so much. It’s almost like they change in sound every time I put them on. That being said I freaking love these things, enough to actually post about them, which obviously by my post count you can tell haha.
