Verifying my recording method #1 (Patreon)

This is my first attempt trying to verfiy my recording method by recording a recording of a headphone which should still sound close to the original sound. 

Unfortunately this pair of microphones I was using here broke in the meantime. I still have another pair which I will try to use from now on. I am currently trying to adopt my compensation to the new mics to get the same results as before.
