Im gonna take a wild stab, but I am pretty sure the Westone 3 is far superior to the x10. I don't havre the W3, but I do have the x10 and I find it to be pretty solid at $90. However, I exchanged it for the A161p because the x10 has a slight more mid-bass hump than I would like (its good for dub-step, r&b and stuff but not as good for vocals) and slightly rolled off highs (but not nearly as bad as the s4i). The x10 has a very smooth and addicting sound, and comfort is phenominal...you put it in your ears and you pretty much forget it. It also has less microphonics than the A161.
btw, where do you find a Westone 3 gold edition for $240?
