let you cans to burn for like a minimum of 30 hours (some recommend 50)
anything that play a full spectrum, or you favourite genre of music in loop will do.

Questions to Sifu(s):
Gear: M50X pair with Fiio E17
1) Burning the cans mean use it (accumulatively) for 30-50 hours right?
2) I realized there’s a bit of hiss (dunno whether if this is the correct term) especially if I played some youtube songs, is it because of the quality of the output?
3) I also realized, if I plug my Fiio 17 power to USB, when I listen to songs, there is some hiss too (again dunno if it’s the correct term)
4) If the cable not screw (put in and turn), there’s some hiss too, is this normal?
5) This one not related to the headphone, but my Fiio 17, display no longer working. So, gone case?
