OK so 6 days with the W4R. Definitely superior to the vsonic gr07 and brainwavz b2 in sound, in every way. However, it is not nearly as comfortable. The nozzles are at the wrong angle and the body of the iem is a tad too big for me. I can't really use it for more than 2 hours without having to take them out. I hear a lot more background ticking noise noise with the W4R, is that the music or the dac?
Fit is such a personal and interesting thing...have the GR07 (original), W3 and W4's, find the GR07, with the odd base they have, impossible to get a good fit with, adjustable nozzle and all. I also find the sound lean and boring, and like the Westone sound much more. The base of the Westones just seems to work in my ears.
X3 and the Westones are a great match...have taken to using the X3 with an external amp (ALO National), it has line out so you can do it, more neutral imo.
