Apple USB-C to 3.5mm Adapter Crackle When Certain Sound Is Played

[AdriftAtlas]

If you play this sound through the Apple USB-C to 3.5mm adapter you will hear a static like crackle in addition to the rumble:

I thought I had a defective adapter so I bought another one and it does the same thing. Doesn't matter what headphones are used. Happens on my MBP and a Dell laptop.

Normal 3.5mm output from MBP, Dell laptop, or any other device does not cause this crackle.

Is there something intrinsically wrong with the adapter design that causes this?

The Lightning to 3.5mm adapter does not have this issue. I also bought the Anker USB-C to 3.5mm and it doesn't have this issue either. So it's an issue exclusive to the Apple USB-C to 3.5mm adapter.
