Personally I tried all 3 filters and settled on the black (warm) filter. I guess besides personal tastes, it also depends on what type of music you prefer. I listen to a lot of vocals, and the black filter gives the voices a nice warmth, and even the blue filters although more neutral, still were a bit "shouty". With the black filters I can listen for hours without stopping; with the blue filters, sometimes female vocals would make listening fatigue set in after a while. But in general terms, the blue filters are probably more accurate, whatever that means. I tried the white ones for a few minutes and decided they are not for me. For vocals they are just too shouty and it was like the singers are singing right beside your ears.
For tips I am now using the triple flange, with the top part cut off (now a double flange). If not for the bigger housing and the cabling problems, I would have preferred the black foams, but I can't get a deep insertion with them so I have to use the triple/double flange because it has a longer stem.
