Every time someone calls me and asks which is best, the W4R or the UM3X-RC I tell them I prefer my UM3X-RC unless your collection has a majority of classical music.
We make more money when we sell the W4R but every time I get a call like this I sell the UM3X-RC.
I'm partial to my own opinion and I try very hard to convey that we are about the best earphones for different price ranges, uses, tastes, etc. based on our opinion.
I didn't write anything about the IE800...
