    • Required: Provide a picture of any special jacks or connectors.
    • Required: Talk about overall sound balance and frequency response signature in subjective terms.
    • Required: Cite areas where measurements meet with subjective impressions. And areas where they don't seem to.
    • Required: Cite fitment and seal issues.
    Measurements
    • Required: Frequency response.
    • Required: CSD (0.25 rise time recommended).
    • Recommended: Harmonic Distortion (THD or D2, D3, etc.)
    • Optional: Other Distortions.
    Subjective Impressions
    • Optional: How does it do in plankton?

    About Frequency response, what is the target compensation? Do you have a standard compensation file to share (diffuse, Harman ...)
    How can I attach my measurement pictures? There's no upload button, only insert url.

    I'll post in a bit about the measurement rig and thought process behind it in the measurements section. There is no compensation used.

    Going back to the beginning of Changstar, I was never a believer of a diffuse field response with headphones. Diffuse field sounds like shit and whoever came up with that idea should be shot. That being said, IEMs could use a little bit of DF equalization. The ear pinna tends add a DF type effect.

    There is some stuff on Changstar regarding the C.U.N.T. measurement apparatus. I'll eventually copy the material here.
