From above, I can safely conclude that few IM70 users uses the stock tips and most would prefer other tips that suit them well. I finally got good fit with one; the big bore eliminates the shrill and improve the isolation. Ring extension made from the stem of Sony hybrid tips were put to improve its soundstage and isolation. I think Im70 needs tip-rolling for quite some time and the result is very rewarding.
