According to the product description, the tri-flanges are gone, but it still says they have a blue foam tip...
Edit: How about the dB Logic EP-100? they are only $15 now, so they could be a pretty simple impulse buy. They have a 3.5 in isolation and a 4.5 in comfort, plus they are small so that works well with my ears.. A pack of Shure Olives would also do some good.
Edit2: Can you wear those facing down?
Edit3: A few reviews are saying these can't block out anything... Why would they say that? I think they don't know what they're talking about :P
Edit4: Ended up getting them in blue.
