hi pinoyman, can't agree more with your reviews on the vortex. just bought mine after testing a couple of iems at a local store (including using Audio-Technica's ATH-M50 as a bench mark) and am really happy with my purchase. I am surprised at the poor reviews on amazon. The vortex is really worth every single cent paid for (considering its relatively low price).   For the rest of the guys reading this: Lows: really like the lows here..if you like heavy bass, you should really consider this. the moonrock is a little more muddy in...
