I had these for about 3 months now.  I can say that this is an eye-opener for me.  I had lower tier IEMs before, namely Sennheiser CX-300, Beats Tour (aweful build quality), Klipsch II, Brainwavz M3 etc.  and I liked the sound of those for their price, except for the Beats.  I always saw the higher priced IEMs like the Westone series in stores and always shrugged off the idea of them sounding that much more in relation to the price increase.  That was until I caved in and bought a UM3X. Honestly, I was disappointed with the sound because I felt it...
