the reason why you can't understand is because you forgot about how everyone's ear is completely different than the next(just like a snowflake or a fingerprint). in that regard, everyone has different ways for getting the best sound out of their ety's. also, it is the same reason why an individual might perceive the sound of the ety's (or any phone for that matter) as bright, while others might perceive the sound as dark. it's not that these people have different ideas of bright and dark sound, it is mainly due to inner and outer ear differences...these people are actually experiencing and hearing the same parts of the sound spectrum in different ways. i myself cannot use the silicon tips because, this is my theory, my ear canal is small. and when i use the silicon tips, they cut off too much of the sound and it therefore makes everything too quiet. i have tried for months to get the silicon tips to work, but the foamies simply provide a way better bass response and soundstage altogether by far. so this is why Etymotic offers various options in fitting these phones into ones ears...everybody has a different way.
