This could be due to a faulty cable, which doesn't have proper grounding or the ground wire got cut somehow. Try replacing the cables with similar ones, if you can. If this is not possible, test your headphones on a friend's computer. or use a speaker to the same device ou are connecting your headphones now and see if the problem is the same.

You may have some power wires run along side your headphone wire. If headphone wires and power wires are routed the same way the headphone's whatever channel is bound like that will pick up electrical interference.

Grounding is the problem. Your headphone needs to have proper grounding wire.

Good Luck

    Thanks Iversh. I think it is probably something to do with the cable. Do you know if if it is easy to take apart the unit to check or is it best to take to a repairer?
    Thanks again,


    On the side that has the wires going into it... remove the Padded ear
    cushion. There is a Black Ring with 4 holes in it this is basically a
    clip you do have to pry a bit at it but it does come off and with some
    luck without snapping, luckily mine didnt. There are then 4 small
    screws exposed to dismantle. And thats it now all wires are exposed
    hope this helps.

    to avoid the cosmetic damage, use some kind of plastic tool, like a
    plastic spoon. After pulling off the headphone cushion, you will see
    the aforementioned 4 slots. Carefully slip the handle end of the spoon
    underneath one of the slots(not through them), and apply gentle
    pressure toward the center of the speaker.

      Locate the faulty connection along your cord. Plug in
      your headphones and play sound through them as you jiggle the cord at
      various points to locate what part of the cord is cutting in and out your headphones and play sound through them as you jiggle the cord at
      various points to locate what part of the cord is cutting in and out.

    1. Step 2

      the cord using wire cutters an inch or so past where the fault in the
      cord is. If this is at the connector, cut the entire connector piece
      off. If it is near the headphones, cut off enough to eliminate the
      faulty section and still allow the cord to be reconnected.

    2. Step 3

      the end of the cut cord. There are three wires in the cord: the left
      channel, the right channel and the ground. The left and right normally
      are colored, and the ground is bare.

    3. Step 4

      repair a poor connection where the cord meets the headphones, match the
      wires with the correct leads coming from the earpieces and twist them
      together. Wrap the wires with electrical tape.

    4. Step 5

      repair a bad connection at the connector jack, acquire a new 1/8-inch
      connector and attach the cord's inner wires to the appropriate points
      on the connector. Connect the left channel wire to the tip, the right
      channel wire to the ring, and the ground wire to the sleeve. Solder all
      the wires in place.

    5. Step 6

      the headphones to a sound source and test for proper function. Jiggle
      the cord at the new connection to make sure it is secure and does not
      cut in and out
    if only feel you are unable to do the above procedure... take it to a repair shop....

    Good Luck

Hi: I have a aiwa nsx 800 mkII I hear left channel normal but the right channel sound very low ?qhere can I fix that?

Check first it is on all functions. If it is then it will be a power amp fault. As the unit has two channels both of which are identical to each other it's possible to check and compare each channel. So in your case the left hand channel parts are your guide to what is right. Compare first visually the two channels. If something looks burnt or damaged or wrong in the right, but it isn't in the left then you will have found the cause.
If everything looks OK, then carry out voltage tests, if you have a meter. Or a sound test. This involves touching with an insulated screwdriver the two channels while the unit is on. Never touch any part that there is only one of. Unless it's an IC and has two channels going in it. You will hear a buzz if it is working or produces sound. Again a good buzz in the left should happen in the same place as the right. When it's load at one point of a part but weak on the other, when it should be a loud buzz then you have found the faulty part.
Please however check first that it's not the headphone socket that is causing the problem. Sometimes the sound will be OK on headphones but not on the speakers. The socket the headphones fit into can cause this.

Buzz coming from elec. guitar pickups only when using Aviom and headphones

It is a definite pickup grounding issue causing hum/"buzz" which diminishes when touching strings. Check the impedance of cable jack inputs and cable which should be 1/4"mono input/output jacks) . A personal preference but effective is to NOT run guitar direct into mixer but through an external amp w/ a headphone out jack . Noise gating/preamp filter also will help eliminate the "buzz"/noise from pickups. It is unfortunately the nature of the "electro-magnetic" beast when it comes to electric guitar pickups .Hope this helps.

Subwoofer is hummig what is this noise

Hum is a constant low-frequency buzz, usually at about 60 Hz or 120 Hz, which results from voltage differences between true "ground" (what you'd get shoving a copper pipe into the ground) and the electrical "ground" of your receiver's chassis When this voltage differential exists, it's called a "ground loop," and the hum it produces is darned annoying. You'll hear the hum mainly from the subwoofer because it's a low-frequency noise, you will need a ground loop insulator they are about $20 at any electronic store

I have a pair of Stanton T62s which I got about a year ago. I moved from SF to LA and now I can only hear static from my right turntable through my headphones. I don't have speakers yet and I thought...

Disconnect the wires to the cartridge on the turntable that has trouble. Then put your headphones and with it powered up. Touch each cable end of the loose wires of the cartridge one at a time with your finger. On two you should hear a buzz, one on each channel. On the other two wires you might get a slight buzz or a crackle, but don't expect anything. If you get a buzz on both channels. Then the cartridge is faulty. If you do not get a buzz on either channel then there is something wrong either inside the deck or the wiring to that deck.

Slow refresh rate - fuzzy picture on HD channels with AT&T Uverse

That would have nothing to do with the fact your TV only has a 60 hz refresh rate, the cable box will switch to the correct format just like it does with 720 or 1080 resolution.

I'vs had my HP Pavilion Dv9000 laptop about 2 months now, and it has been great. recently however sounds have only been coming from the right sound channel. The left side just makes a starng buzzing noise...

There is a problem is the sound card. The HP laptop should be still under warranty, take it to the supplier to get it repaired under warranty. If you try to fix it yourself you most likely will void your warranty.

White noise in left channel on my Vestax PMC 06 pro-a DJ mixer

try it with nothing plugged in to the inputs, if there is no noise. most likely its the turntable, cd player, or whatever the input is is the problem. or try plugging the mixer into a different area of the house/room. its like if you were to put your cell phone by a mixer, or speakers.
