So spent the last week listening to these. I've noticed that they are somewhat fatiguing for me... I think that sub-bass boost/rumble may be causing it. Also does anyone else feel like the bass sounds a little too forward. They don't mask the mids but they make the mids sound further away to me.
ericr: the phonak tips would definitely be worth looking into imo. I like the modified meelec tips a bit better just cause they fit like a glove for me (phonaks fit extremely comfortably as well). The phonaks seem to make the sound even more clear/airy (compared to stock and westone star tips). They don't emphasize the bass like star tips do. Overall they sound really crisp and clear, they seem to bring out the texture of the instruments.
For those that prefer the SM64 to the w40/w4r would you say the w40's do anything better than the sm64s? Would you consider the westones 'smoother'.
