Hi, I've tried searching through the forums, but couldn't really find anything on this question: I'm going to be taking a long-haul flight shortly, and need some tips that will give me good isolation with my UM2s. I know people recommend the Shure EA306s, but I'm afraid they'll be too big for my ear canal. Now I'm looking at the ER6i tips, but don't know whether it will fit on the UM2 nozzle. Can anyone give me advice on this? If modding is involved, what specifically would I need to cut?
