I live in Asia. That means getting my hands on IEMs like Westone is a very hard issue. Took me awhile just to look for a store that sells IEMs. I got my Westones sent to USA in March. Just recently I only have the chance to get it...
I don't prefer Westone UM2. They broke on me 4 times. And all I did was drop it on the floor. And I'm 5ft 3! I would recommend the Shure SE425. I would take that anyday. And I find the Shure SE425 are better in terms of SQ. Brighter...
