The tips I used were silicone, narrow bore tips. I try to avoid foamies when possible, since I find that they dumb down the sound by killing treble and boosting midbass. When they're officially available in Korea, I'll make sure to bring my eartips with me and try them all. Unfortuately, I highly doubt I'll get a good fit with wider bore tips (Spiral Dots, SymbioW, Sedna, etc.) given the shape of my ears.
