SETUP, CONDITIONS AND PROCEDURES ​

Periodic Pink Noise running on the music app in the background Microphone on "High Range" setting 32768 FFT points dB scale: 30dB to 85dB Right channel at determined at 94dB +/-1.0dB averaged Resonance point normalised as close to 8,000Hz as possible (may not be possible due to shell dimensions) 30-60 second average Left channel maintained at the same volume as right channel



DISCLAIMERS ​

1. A Frequency Response graph is not in any way an indication of good sound quality. Think of it as flavours, like in ice-cream. The FR is like the branding at the side of the tub telling you the flavour of the ice cream. It's not going to tell you if it's good ice cream, but at least you have a way of finding out if it's the flavour you want.



2. Measurements in this database are raw and based on the IEC60318-4 standard. If you are going to compare my measurements with others, at least make sure that both equipment are standardised.



3. Flat on the graph DOES NOT MEAN flat in real life. The fact that IEMs bypass the outer ear structure necessitates higher SPL in the 2-5k regions as compensation (see: Diffuse Field, Head Related Transfer Function, Harman Target).



4. Measurements are meant to complement subjective impressions, not form the basis for them. I get that certain people like to paint me as some sort of objectivehead figure where all I do is look at graphs and determine quality sorely off of said metrics. 99% of the IEMs I've measured, I have listened to as well. If not for the graphs, one can also take this database as a list of IEMs I've tried and auditioned, and the graphs simply being proof of it.



5. Unit variation is a thing. I do not control what demo units the companies provide to me or to their distributors (where I usually do measurements). If you find issues with my measurements, it can be any of the following:​

a) Inconsistent manufacturing

b) Broken/malfunctioning units (in a way that is not immediately obvious)

c) Horrible channel matching

d) Measurement error (yes, I am human, I make mistakes sometimes)
