I wondered if anyone else has experienced this with eGrado headphones or perhaps with SR60e (since they share same driver as eGrado) headphones.
On my eGrado phones, the right driver (and only the right driver) rattles on frequencies 65Hz and below at moderate volume (7 steps below max on iPhone 6S Plus) but is fine at 70 Hz and above at the same volume. The left driver is always fine with those same frequencies even at the "higher" volume.
Test I am using:

This pic shows the volume at which 65 Hz and lower tones rattle the right driver:
I've heard others mention in reviews of the eGrado driver rattle, but I haven't noticed that anyone tested frequencies/volumes, or found that it was only one driver, as in my case.
