My biggest problem is that this happens passively whether or not music is playing. It can't possibly be my music files if it's simply a thing that happens when plugging it into the DAC, computer, Gameboy, etc.
Edit: The biggest difference between that is I don't get static with my current set-up passively on many headphones I previously had static on in the past. At the moment, the only IEMs I shortly tested on my set-up that have no set-up are the NuForce NE-700X, some Westone IEM that fits with memory foam tips, and even a lower quality Koss IEM that has a mic. I haven't exactly tried that many IEMs though, but I'm a little sad that I have this static in the first place.

If you don't want to change the souce, you can try an IEM that is unable to reproduce high frequencies, or an IEM that has less sensitivity (maybe 100dB is low enough).
What sources are you two using? I imagine you both don't have this hiss. At the moment I'm using a Fiio E17, but I'm also very familiar with how different sources can affect that. For example, when I used a Sennheiser HD280, I could hear this same passive background hiss without using anything but when I plugged it into an Audinst HUD-MX-1, the static was not audible at all and the same thing happened with the E-17. I just want to know if I really do upgrade, how much more of an upgrade do I have to make for the static to "disappear"?
