hi , i have hd58x and when i plug it to the pc it doesn’t sounds right there’s like a buzz in audio ( because of the pc and i don’t think the aux jack is isolated ) but when i plug the hd58x to the laptop it works just fine , so
first thing - will this dac work with my hd58x ?
2nd thing - will this solve the problem?
MjoodeLOL sorry for only seeing this 1 year later, so I hope you already solved your issue.
But to answer your question:
1st thing - This is DAC only, you'd then need an amp to hook up to your HD58X.
2nd thing - This is usb powered, so sometimes the noise will carry through usb. So there is a chance it might still be ok, but if you're worried it's best to get a dac and amp that's powered by its own power (i.e. plug into a cellphone charger or something then plug into the wall, or has its own power adapter).
In any case I hope you got everything sorted out already lol.
