btw, it's senny px80 portable not px90....anyways not a prob. And tf10 is not a hyped one imho.with 3 BA,removable cable design etc @ a price ranging from $100(GF sale) to $239(current price) it's still worth. BUT the fit is the major issue and the barrel almost extends 75% from the ear, secondly the stock cable (guess some batches) have the issue of very short life.The Neon Blue shell is sexy and If i'm not wrong UE registered it's name strong into the h(ear)ts of consumers/music listeners than Pro's thru their flagship model IEM(was) tf10 (maybe since 2006-2012?) until UE900's birth. whatsoever, I had been a recent victim of tf10 stock cable and shared some info on that in the following link, which I thought might be useful for those who's seeking an answer of short lived cables.
