Was looking towards a UM or Rooth cIEM.
 
I currently use my Ultimate Ears Triple-Fi 10s for side-sleep.
 

 How do you sleep with music on?

I actually don't listen to music. I listen to ASMR videos on youtube to wind-down before sleep.

 But Infoseeker those things are huge! how the hell?!

 
I actually use these IEMs with the FLIP MOD. Where as you can see here:

They fit snugly along the contour of the ear and don't stick-out. So believe-it-or-not they are just as good as any other IEM for sleeping. They also are very very subtle when you are out in public when worn flip modded; nobody has ever pointed them out to me in awkwardness.
 
 
 
Anyways, I am upgrading and looking towards a custom IEM. And this is my concern of interest I wish answered:
 
How many drivers can put in my set-up before I start getting a bulging mass of a fetus sticking out of my ears? Which would be counter-productive for comfort and especially side sleep.
 
On a side-note, I don't want my Triple-fi "V" sound signature. I want something more forgiving and warmer.
 
If I want to make a dream list, I mind as well ask  for a wider sound stage; and higher resolution detail whilst still forgiving.

Universals are the way to go if you're looking for IEMs to go to bed. The difference is not the number of drivers but the acrylic structure itself and your ear shape.

By universals you mean to find something like the triple-fi but one that is better fitting?

Yep

6 perhaps? The Earsonics SM6 sticks out a fair bit.
 
Are you sure you need a good quality IEM for this? There are various 'sweatband' headphones for wearing in bed, which might not have any comfort issues.

Well, I mainly wanted some IEMs for isolation in the subway. I just wanted to them to also to have a small footprint that can be practical for sleep too.
