The ringing is not as loud and subsides much faster when plugging in the headphone, which may be less of an issue for those willing to wait while the ringing goes away before putting headphones on. Sometimes I can barely even hear it after plugging the headphone in with the headphones already on. However, the bigger issue for me was the nearly constant ringing that occurred while listening, and any slight, and I really mean slight, movement of the cable would produce ringing, loud enough to be heard through the music. Given, I was using the seemingly highly microphonic cable that comes with the he-500 at first, but it was also occurring with the he-400. Also, touching the vali to simply turn up the volume would produce noticeable ringing that was audible through the music.
What this ultimately lead to, before getting a replacement, was me sitting as still as possible, not changing the volume, and feeling pretty constrained. Post-replacement I am able to really the enjoy the music more while worrying less about the aforementioned issues.
