I recently bought Razer Hammerhead Pro V2, when I use it on my laptop while its charging, i hear a hissing sound, not very loud but it gets annoying. When I mute my laptop the hissing will be mute as well or when I remove the charger. My laptop had a history of short circuit or something so its charger is just a replacement. I tried other cheap earphones on it and I don't hear any hissing noise however, when I use my razer earphones on my PC in our office it doesn't make any hissing sound so I have no idea what is faulty. Can this possibly damage my earphones? This is damn expensive and new I can't risk using it if it has a high possibility of damage due to ground loop.
