  1. Or maybe not :D. I've been 3 metters away from my PC but no difference. Also, I've used them with my CD-player while the computer is turned on. So, I do not believe that the coils (or that part of the headphones) are directly affected by magnetic radiation. I think the cable may get this electr-magnetic "crap" and somekind of resonance (I don't know) creates this noise. Ok, gurus: what's the problem? ???
  2. As i said before: I've tested headphones with my cd-player and it sounds ok. There is a small noise but nothing compared with this. I do think there is nothing wrong with them. I don't understand why such a loud noise. Too long cable, resistence to big/small. I know that the soundcard is causing this problem, but in conjunction with what? They have been tested on other computer and they seem fine.
  3. The power source is not underrated. It will probably work with other soundcard, a PCI one, but i was wondering if there is another way... technical one? :)
  4. Hello, I wasn't sure where to post this, so here i am. I bought three months ago an AKG 66 Headphone (with a 3 metter cable) and i have a problem with "background" noise. Even if i don't play music I hear sounds (no, i am not that paranoid ;) ) (similiar like you hear when listening to an AM Radio frequency, but not that loud). If I start playing some music I can cover that noise but it is really annoying, and i definetly don't want this as a solution. This noise starts at the same time as i turn my PC on. I've noticed that if I plug out the headphones and insert back the cable in the soundcard there is no noise for about 10, (15 ,20?) seconds. After that, it starts again. ( if i start playing music louder, it starts exactly that moment) Both left and right phones are affected, but on the right side is a more pronunced. This noise is influenced by moving the mouse or scrolling windows, moving windows etc. Monitor does not create this because this happens even if I turn it off. My sound card is an AC97 onboard (i know it rocks :( ). Could the video card interfere with the soundcard? I thought about current on my computer's case. I've connected that case to a pipe to be sure that is grounded. No effect! I've removed my harddrive, cd-rom, I've also took out my motherboard so it won't make contact with computer's case. Still no difference. I've tested headphones with my cd-player and it sounds ok. There is a small noise but nothing compared with this. I have that noise with all headphones. I thought it may help setting everything (like modem, aux, mic etc) to mute in widows (and linux) but that didn't helped. I've contacted my motherboard manufactuer but they couldn't help me. I've rewritten my BIOS, but guess what? NOISE again. I've posted my message on different computer forums but no one gave me any help. I've noticed that if I keep about 20-30 centimeters of headphone's cable perfectly(as much as i can) straight there is almost no noise. I've tried to tell you anything i know about the problem, but if you need more info please ask. I need a filter that would allow only low frequencies to pass? (i don't know how you call that in English). Hope someone has a clue... regards, acker PS. It looks like my ethernet card influence this although does not creates it. Mainboard: CM33-TC CPU Celeron Copermine (1Ghz) 128 + 64 SDRam 8 MByte shared onboard Trident Cyberblade i/1 video 1 Realtek Ethernet 10/100 card 240 W power supply Latest BIOS available installed.
