ck10s.  partially because they're my only top tier, and partially because i don't see a need for another set..

^ your wallet thanks you Unfortunately for mine I got the e-Q7 shortly after getting the CK10 and I have some more coming in the next couple weeks hopefully.

My IE8s are my most used IEMs. I love the sound, the comfort is great, low microphonics, etc.

 

[SoupRKnowva]

my jh-13's, because right now my only other set of iems are some marshmellows that i hate though even if i had some top tier universals i dont see myself using them over the 13's...

W3 because it is the most complete IEM I have ever heard as well as a bit of a fun factor in that it is not overly neutral.
 
Big full sound yet VERY detailed throughout the whole spectrum.  Big soundstage, crisp treble and top 10% ergonomics of any IEM ever made and efficient where no amp required.

JH13.
 
Sound, neutrality (monitoring and mixing), comfort, sentimental value.

Got to be my Monster Turbine Pro Coppers, sold the rest of my iem's to fund them and can say honestly that it was a great move. Really don't need any of the others now anyhow. I just need to work on the fit though....then they will be perfect and used EVEN more.

Gotta say my MTP coppers too, although im still breaking them in they sound just great.  Makes all my music sound good, unlike my S4's which only half my music sounds good.  gotta say that the s4's are great for watching transformers though, lol

Before my kitten decided to have the cable for breakfast, my M9: they were comfortable, nice sounding, good isolation, low profile, cheap enough not to be a great loss if I they break, etc. Perfect in all senses.
 
Now that I finally ordered the M6 I think I will be using them mainly, except for workout.

Westone 3 with olives. Comfortable, zero microphonics, and good sound quality.

Sennheiser IE8, it's so smooth...

 

[kmhaynes]

Right now, MEElec M9 for listening while out and about.  RE0 gets used for more critical listening sessions at home, usually.

Klipsch Image X1 for daily work use.  This with shure olives isolate a hell of a lot. Sadly it is a bit rough on the ears though.  Would use my westone 2's but they don't isolate as much if I use the flange and can't seem to get a descent fit with the olives on.
