Bought both of them, so far just have the Turbines. They are a big step up from my ADDIEM that crackle constantly (I think it has to do with ear wax getting inside it). As expected the bass is very strong, probably too strong imo, but still sound awesome for most songs. It is very finicky with the flange tips, requiring the correct placement or else the bass is not good. Overall not as good as my Grado SR225i's (as expected) which were much more detailed. I do really like the fit on these though. So far I have just been using the small flange tips and these are the first IEM that actually stays in my ear. I can sit for hours without needing to readjust. It does get sore but it doesn't come out, even when walking to class. I'm guessing other tips may be more comfortable.
What is the verdict on Turbine vs TripleFi? Do Turbines compare in any way? I'll probably just keep one of these and sell the other cheap to some lucky headfier :)
