thanks for taking the time to do this, hopefully you liked the track at leastYeah, that song will sure test an IEMs capability to handle complexity. I’m happy to report that the Believe handles it really well. While all the “chaotic” sounds are going on, it still separates them all, and placed them within a 270 degree circle around me. It didn’t fall apart when I turned it up, and the limiting factor was really my ear drums. Past a certain point my ears just tense up. The Believe is legit. There is, however, some sibilance. Not much, and it doesn‘t bother me, but there is some nonetheless.
I'm sure this will be sibilant on pretty much anything considering it's probably just produced to be that way
