Thank you for reaching out to me.
My sound signature preference in general is this --
Balanced, wide and tall soundstage with relaxed presentation that also has some 3D spatial holographic element.
I'm using Empire Ears Supra custom, an old entry CIEM thats long discontinued but it's a competent dual driver.
My setup is sometimes either directly from my phone or with a Fiio Q1 DAC amp.
I would like to have more soundstage and lush vocals / midrange, tighter bass and maybe more treble but won't be sibilant to the ears (I'm fairly sensitive to sibilance)
Edit: I understand that I do not have multi thousand dollars worth of hardware for my setup but I do believe that there are always something for all range so do forgive if some of my sources appear rather...unimpressive.
