Try modding the foamies. This is the easiest and cheapest mod you can do and it really opens up the Etys and puts bass and mids into the sound. Get a foamie tip, find the shiny side, then find a the spot 2/3 of the width from the shiny side, and cut the foamie to trim 1/3 of its width. Put the foamies on, and you will be blown away.
I seriously do not know why all people do not do this. It transforms Etys into something truly special.
Some people who are familiar with this mod, say that you can achieve the same affect by using yellow Shure tips, which are narrower and fit onto the Ety post, so you might try them if you don't want to cut the Ety foamie.
Hope this helps.
