Here you will find the frequency response and impedance graphs on IEM and earbuds I have measured using my home-made measurement rig. While accuracy can not be 100% guaranteed, I do have good confidence about the data collected. More measurement will be added in time, but you are welcomed to contact me to suggest for any particular IEM / earbud that is under my collection and I should try my best to accommodate.

*Note that earbuds measurement is significantly more difficult than IEM due to the nature of a looser, no-sealing fit, and therefore care must be taken when interpreting their data since they can measure quite differently even with just a slight change of fit.

*All frequency response curve are diffuse field compensated.
