I would say it is hard to quantify the changes, but if I were forced to - to my ears the ER4XR is noticeably better than the ER3XR.I got the ER4XR, which from what I've read is maybe 5% better than the 3.
I am sorry to hear that you're in the (relatively small) group of people that experience a fit issue with the deep insertion.I really like the sound, although regrettably, the fit has been an issue. The foam tips that came with them make my ear canals itchy. The silicon flange things go awfully deep and hurts in one ear. It's fussy regardless, and I don't like the fact that I now worry about whether I'm doing myself harm.
For what it's worth, I seriously doubt you could harm yourself... Also, several people in your situation reported they resolved the issue by inserting half-way (instead of all the way). Might have a small effect on the sound, but a big effect on comfort
Lastly, did you try both 2-flange as well as 3-flange tips? One type might fit you better than the other...
