I am having mixed feelings about the W40s recently bought. It's been played for ~20 hours now. I find them relatively not well-defined throughout the frequency range compared to my IE80s (recabled). They do sound generally balanced and easy-going, which might be a good thing for casual listening, but I feel missing something in the top highs, strings and piano is lacking the 'shine'.
Bass is also a tiny bit bloated than the IE80s, although that may not necessarily be a bad thing.
Can people tell if this is the normal sound for the W40s? Or is it the tips/fitting not optimal? I tried both foam and silicon tips, and am using the non-mic epic cable.
I read that BA drivers don't change a lot in terms of burn-in (I did notice significant improvement within the first 10 hours but not until now), if that is true then these may not be to my liking...
