Hiya,
Its quite a tough one to call, it seems by your tastes / requirements than any / all of your recommendations are required...
Probably the best all in one IEM out of the three you have chosen is the ETY ER4P, but it might sound a bit lame in the bass department (if you've come from earphones such as the Sony MDR-EX70/71 especially!!)
Hopefully in your thread you have started they have given you +/- things for all the IEMs in your list, but if not, then my nod will go (very hesitantly) to the ER4P, the SF5P are great, but can be a bit ragged / in your face, and they also have the least effective seal of all three you have listed.
Hope it helps

Basically: Shure E4G vs UE Super.Fi 5Pro vs Ety ER4P
I listen to a lot of dance music (especially drum 'n' bass) on my iPod and my laptop (w/ Creative Audigy 2 ZS soundcard) but also other genres of music such as indie and not-too-heavy rock.
I am looking for IEMs with good isolation as I don't want to be distracted/disturbed whilst studying in the library, on the train/bus (daily commute) and when flying (I fly long-haul quite regularly). Despite listening to a lot of dance music, I don't want to be overwhelmed by bass nor do I want it to totally dominate the mids and highs, but bass is obviously important.
I have picked out these three IEMs as they seem to be the best things around for the money. I am very tempted by the UEs unless someone thinks I should change my mind!
Thanks for your help guys
