Good observation there... Guess I'll be seeing you in a few months then my friend =) The current plan for us is to fully commit to our titanium shells, as they are just better than traditional acrylic shells in SO many ways. As you can imagine, translating that to custom IEM's is a bit tricky. We'll have more info for you all regarding this as well as the future of UM soon. 2019 will be a big year for us!
