I never thought they could match the sound quality because of the way the 598's are housed. I was told that removing the black rubber tape would actually make them more bassy, was I told wrong? I am tempted to put them back in to experiment. What I want overall is the most accurate sound I can get but for some reason if I can't hear very much bass it doesn't seem balanced enough for me, I always have to use an equalizer to enhance the bass from 40-80hz by a few DB, I used to be a basshead and would never have liked these headphones in the past because of their bass but I have grown up and my taste in music has changed.
If I listen to classical music, or jazz or classic rock then I am satisfied with the bass when not using an equalizer but if there is a song that has deep bass I like that subwoofer at a low volume sound. These headphones at high volumes can put out pretty good bass if using an equalizer but doesn't an equalizer defeat the purpose of what these headphones are mean to do which is sound balanced and accurate?
Anyway the black rubber tape removing it would make the sound stage open up and sound better right?
