hey everyone, so recently i decided to try out the Beats by Dre studio headphones.. however when I plug them into my PC (just a standard onboard sound card), i hear a lot of excess noise when no sound is being played on my computer. I'll hear what sounds like filmstrip going through a projector, some random beeps on either side of the headphones when i move the volume up and down, and a "shhhh" white noise. I only hear it when I turn the headphones on. Also, when I plug in my seinnheiser hd555 headphones, i can very faintly hear the beepings when moving the volume up/down, along with the white noise being activated/deactivated when I move the volume to 0 and higher (but I can't hear the white noise when the volume is unadjusted). note: Even when I put the volume output to 0 on my computer, i still hear the sounds. Could this be the noise-cancelling part of the headphones (if so, it's very annoying), could it be my sound card? I tested both headphones on another computer in my house and the white noise hiss sound is still there, but tthe beepings and filmstrip sounds aren't.
