-[We provide a frequency response measurement here](https://ploopy.co/wp-content/uploads/2023/02/HD6XX-Ploopy-FR.jpg) that we believe is representative of the overall sound quality of our Headphones. This appendix will explain what the graph means and what information it includes.

-## Comparative measurement
+A big thanks to [oratory1990](https://www.reddit.com/r/oratory1990/) for measuring the Ploopy Headphones!
 
-To provide context for the provided measurement, the Ploopy Headphones aren't measured independently. Rather, we contrast it with a measurement for the Sennheiser HD6XX.
+The equipment used to measure the frequency response of the Headphones is as follows:
 
-In the graph, the blue line is the Ploopy Headphones, and the grey line is the Sennheiser HD6XX.
+- GRAS45BC-10 KEMAR head and torso simulator
+- GRAS KB5000/5001 anthropometric pinnae
+- APx515 or APx526 Signal Generator/Analyzer
+- APx1701 amplifier
 
-Given that the frequency responses for the HD6XX is well-known, accurate comparisons can be made between "official" frequency response graphs for the HD6XX and our measurement.
