My second day with HE-400s. The music is still very enjoyable but in certain sub bass heavy songs I notice that my right driver has noticeably more impact than my left one.
I ran a 10sec 30hz sine wave through HE-400s at my typical low-medium listening volume and my right side rumbles while left side sounds few dB lower. At first I thought it were my ears so I flipped the headphones and now the left side rumbled while right side was noticeably quieter. I've tried swapping cables and switching from external DAC to my soundcard but the effect persisted. What's going on here?
Has this been observed before? Any thoughts or suggestions?
Here's the .wav file.
Edit: after more testing it seems like 20-40hz range sounds right heavy with my HE-400, but when I get closer to 40 & higher bass starts shifting closer to center and the rest of the spectrum sounds fine (at least as far as I can tell). Would this be considered a defect or within the acceptable HifiMan +/- precision range?
