So I recently have been interested in the two UIEMs after my Monster Turbine Pro Gold decided to start breaking. Anyways, I was curious as to see what the general opinion between these two sets and the reason for it. I already purchased the UM50 for $499, brand new, and was hoping to convince myself that the UM30 are better or the UM50 is not worth it. In reality, I want to know which sounds better or what their characteristics that make the sound similar and different (the usual stuff).
Prior to this thread, I have read the Westone UM Pro Series thread but with so many mixed reviews I am unsure what to think.
