So for me. No matter if im listening on the 6xx or hd800s, I have to lower volume to avoid clipping. If you pay attention to the music without lowered volume for clipping option slected, you will notice the vocals in bass heavy songs fading in and out. It will slightly sound like a veil is put over their voice whenver the bass comes in heavier. I use the song Esskeetit by Lil Pump, and Boo'd Up by Ella Mai as an example. If you pay attention you will hear the bass veiling out their voice. If you turn on the lower volume to avoid clipping, you will have better seperation of voice and bass. Much cleaner
