Electric hum in Headphones at high FPS

But I do agree with you and have the exact same issue as have (although I kinda got used to it by now).
The funny thing about reports of this issue is that every single one I find either has the same MB or GPU as me AND the HD 558, it might as well be a manufacturing error from Sennheiser. (But I doubt it and will try a DAC once I get some money)
Coil whine is from a physical object in the GPU resonating. It can happen in any electrical device that has a coil.
Yours however is different. The GPU power (from the PCI-e slot) is too close to the audio traces. The electrical noise jumps from the GPU power trace to the audio trace and then you hear it. Using V-sync will lower your FPS, and so your power draw, so you'll get less noise.
I had this problem after adding in too many PCI-e devices and a high powered GPU. I later on slapped in a dedicated shielded SPU and bam, the sound was gone. Since then I've heard nothing.
