What is the experience of people who own this product? What is your comparison of the three and what do you think about the price? Thanks a lot in advance. I use a KA 17 with Porta Pros, AKG 712 Pro, KPH40, and KPH30i.
The Elixir is the only IEM of those 3 you mentioned, the other 2 are earbuds and if you are in that price range, get Rikubuds. 
You are right; what I’m looking for is something good to listen to in a small form factor, not necessarily an IEM. I might have missed the category.
well if you want small then my gen 3 rikubuds will be it.
If you want the value for money in a small package, they are:
Yincrow X6 (earbud and competes with $100 models I’ve had)
7hz Salnotes Zero:2 (IEM)
Moondrop Chu II (IEM, I travel with these everywhere, small and stealthy looking too)
All are easy to drive, a U.S. version of the Apple 3.5mm adapter for $9 will light them up really well (and your headphones too)
I just want to make clear I didn’t mean small form factor for IEMs or earbuds. I meant small form factor as in smaller than on-ear headphones since I have the Porta Pros and KPHs.
