I tried using the tape mod and have the bass dial half way.. The mids seem to come up to the for front more making the detail more noticeable.. Took a little bit to get use to it.. Brain burn in.. To really sound good.. The bass seem faster and alot tighter.. I'm kinda really liking the ie80's this way alot.. Makes them sound more reference sounding.. Imo can definitely hear more detail..
Im trying the tape mod right now, definately more detail present than before. To me it seems like going from listening in a small hall to listening in a medium sized room. It sounds more intimate.
Need to test it with different types of music to see if I keep the mod but great to see you can get such different results from this IEM with tuning/mods.
