The best I’ve found so far are the Coreir Brass tips. The medium fits pretty well but cause the IEM to stick out a bit. Do the smaller sizes have smaller metal bores or is it just the silicon housing that is a smaller size?
Answering from memory, so please don't quote me on that. I am positive it is just the latter. I can get a fit with pretty much any IEM I have here with the L size, but not with M, for instance.
But, FWIW, I think they should start offering a shorter stem version for the applications you've mentioned.
Cheers.
