I use mine with blue filter and white with green sony epex10(?) tips. The tips tame rhe treble. I do this cause the best sounding setup makes them cut out really fast..this one does not, not even shortly after showering. Sound wise i prefer black with wide hole tips thoExactly.
I actually only use it with the red bass filter..... Dark and intimate. From a personal perspective it's the most enjoyable iem in my collection.... which makes me want the A6 as discussed above!
