A "problem" with this hobby is that we are at a point in history where significant improvements continue to come through the door. Frankly, I don't have enough hours on my UM3x (with replaceable cables) to consider replacing it. And I also feel that a $450 earphone should have.replaceable cables, no matter how good the stock cable is. I don't have any wearability issues due to the UM3x's replaceable cables.
However, I must admit that HeadphoneAddict's review tempted me. I do feel that I would appreciate some of the differences he noted for the Westone 4. But I will be "strong". At least for a while. As much as I enjoy the technology, for me it is really about the music.
