Introduced at CES this year is a pair of in ear, diy, custom fit headphones. Who knows about the sound quality, but for someone who can never seem to get a comfortable fit with any pair of in ear headphones, it's quite intrigueing.

I had never been able to find a set of earbuds that didn't constantly fall out until the Bose IE2s came along. They stay in my ears rather well and have reasonable SQ but they are rather "leaky", letting a considerable amount of ambient noise come through. But up until now they were the only game in town for my ears.
This system looks interesting and might be a good alternative for me. The 2 driver system looks like it has the potential to be a good sound upgrade at a reasonable price increase.
Hopefully someone will review them soon from an audiophile SQ basis.
