Do any companies make custom sleeves for the 1plus2 to turn it into kind of a CIEM, similar to how Sensaphonics makes sleeves for the Shure lineup?
I am wondering the same thing since I have to small ears for universal tips of "1plus2 size". The Shure size is much easier to fit with universal tips for me.
Have you asked sensaphonics about it?
Sensaphonics said they can't do it.
