Help me choose E2c/ER6i/superfi.3?!?!

I'm currently using sennheiser px-100's and I LOVE them. I do work in a very loud environment most of the time and am hoping some in ear phones will help a little bit. I'm looking to spend about 100 USD on my new toys. I've narrowed it down to 3

the shure e2c's
the etymotic research er6i's
the ultimate ears super.fi3's

I listen to mostly rock, so good bass is kind of important. any advice/real life experiences anyone can offer would greatly be appreciated...thanks!

E2. But they are kinda unconfortable. The Super.fi 3 is the most confortable out of the 3 you listed, but I think the E2 would be the best for your music genre.
