Am I crazy?! So my back story is that I don't get a great fit with my UM1s. The only way I get a decent fit is with the tubes of the Etymotic Foams + Shure E2 medium pieces. None of the foams work well enough on the left ear. I know that the UM56 will work with the UM1 and Shure models so if I wanted to upgrade later I could use them still. What are your thoughts? Also, how long should the UM56 last me?
