I believe any buds will do the trick. The difference of different type of buds is how deep they go in frequency. Those that come with the iPod only go down to 20Hz. If the frequency of the Paraliminal is lower, it will get cut off. However, there is no way to notice if it gets cut off. I always used buds that go down to 8 or 6 Hz as I use them for Holosync too.
