I recently purchased an E07K to amp my DT770 Pro 80 ohm headphones. It works great and really makes my headphones sound alot better. However, I do seem to be having an issue.
I have my setup like this Headhponts>E07K>Xonar DX. I do not really use this for portable use, just at my computer. So whenever I try to listen to my headphones and charge it at the same time I notice some strange static. That static increases majorly when gaming on my PC since the GPUs ramp up. I have tried unplugging all other USB devices with no luck. IF I charge and use it as a DAC and unplug it from my sound card, then there is no static.
Any solutions? Or am I just kind of SOL? Would I be better off using something like an E9? I know its overkill. I also read somewhere that the E9 is not ideal for the 80ohm dt770s due to something with 10ohm output?
Anyways, any help is appreciated! Thank you!
