I think we've always agreed on the IE8 and the Westone earphones 

^ As always, it also depends on personal preferences like music genres, listening volume and whatnot.
Just for example, I agree the W4 are technically better overall, but the IE8 have better dynamics at low volume, where the W4 sound a bit lifeless. (Speaking of which, the K3003 really trounce the W4 at low volume, they're probably the best bedtime IEMs I've heard so far.) Of course, at mid to high volume, things change and the W4 come alive, whereas the IE8 turn into a boomy mess.
Btw, the IE80 I A/Bed with my IE8 had only a few db less midbass emphasis, so their overall signature was still the same.
Agreed, it's ridiculous how much I enjoy the K3003 in casual & bedtime listening.

Will someone help me to choose from this three? You're opinions will be greatly appreciated..

I considered my budget first.. I can't buy 2 earphones and unfortunately can not buy an 'entry' step level of earphones because I have raised my funds just for one IEM and also because I'm still a student. I'm asking this now for I already have my money and I'm planning to buy within a week or so.
My preferences are very durable earphones that can withstand time and reckless handling.. The cables are always the problem of my past IEMs..
The sound most especially is considered.. I'll be using it as studio monitors, everyday earphones and those I can comfortably sleep with them on.. Comfort is much preferred.. I don't need much accessories but just need to find the right ear tips thaf'll fit my ear..
Microphonics may be an issue for me too but can also be neglected if the IEM chosen is what suits me most..
My country (Philippines) don't have display of these earphones and I'm going to buy it internationally.. Preferrably on e-bay.. But if you can recommend where, I'll try to make good point of it..
Thanks for your time.. Please be considerate of my comment.. I'll try my best to be updated..
This is if you can only pick between those three: If you're going strictly for durability I would probably skip the HiFiMan. If you've never had a deep-insertion IEM before and are after comfort as well as being able to sleep in them, I would skip the ER4 as well. The W2 is one of the few higher-end IEMs I felt comfortable sleeping in. Comes with tons of tips and has a pleasant, balanced sound to it.

First, thanks for a truly great comparison of the IEM market. Gotta ask if you looked at Mee A161p when you tested the A151s. I just got the former and I'm wondering if I would be better off with the Shure SE215s. I wish I had seen this post before getting the 161s. Would have saved me a lot of research and worry!

The A161P had not even been announced yet when I reviewed the A151. However, I did review a re-badged version of it later - it's found in this thread as the Fischer Audio SBA-03. I also compared the SBA-03 to the A161P here: http://www.innerfidelity.com/content/dandy-meelecronics-a161p-and-fischer-audio-sb-03
