The left speaker for my quiet comfort 2 headphones is starting to give this static sound. I've unplugged all the cords so I know it's the speakers fault. It also sounds like it's coming from the noise canceling.

Hi,

Plug the speakers into your phone and see if you get the same hiss. I do not advise running your pc sound at 100%

Have look at this. https://forums.tomshardware.com/threads/hissing-on-speakers.216047/

A number if things can be wrong with it, from the audil preamp to the the audio amplifier. Even as simple as a bad volume control. Does the actual noise change patterns when you move the volume?

That means that if too much power is going to the speaker or extraneous signals are being picked up by the wiring, it can come through the speakers as static. Stopping static requires finding and eliminating that extra electricity from transmitting through your speakers.
If you're still hearing distortion, turn down the volume on your amplifier until the distortion goes away. If the volume is too low to be easily heard, the problem may be that your amplifier produces too much power for your speakers to handle or that your amp and speakers have different impedance ratings.

Hi,

The most common cause for this, is a loose wire connection to that speaker (as opposed to the speaker being faulty).

Has anyone pulled the cord too tight or tripped on the cord? If yes, then the internal wire connecting that speaker has an internal break somewhere.

Try the following:

1) Plug headphones into music device and turn on.
2) Gently press the wire 'in' at the left earpiece (or wiggle at the earpiece end). If sound returns intermittently, then you have n internal wire break in that end of the cord.
3) Gently press the wire 'in' at the plug where it connects to your player (or wiggle the cord at the plug end). If sound returns, then there is an internal wire break at this end of the cord.

In the case of broken internal wires, it is possible to repair.

Although very fragile, it is possible to resolder these tiny wires (you'll have to burn off the enamel coating around these wires first) back onto their respective connections, or onto a new plug.

Good luck....

there are two reasons for which your left ear head phone is not working:
1.If the insulation between the wires(copper leads inside the cord) fails....the two leads gets short circuited and it will stop working...OR some times the cord ll be looking good but inside one of the leads got cut then one of the headphones fails...
the solution for the above problem is dont wrap the cord...this ll lead to cut or insulation failure....
2.the speaker in the left head phone got failed...
dont forget to rate me...
good luck...

Well the jack you plug in has three surfaces. So when you pulled it part way out then the left speaker part of the plug came in contact with the right speaker contact inside the jack and it worked. Speakers are good so if you have checked your volume control in Windows and checked that the balance control is centered it could be that your sound card is defective. You didn't tell me what kind of computer you have and if the sound card is built into the motherboard or if it is an add on card. I don't know if you only have the Window's sound control in Control Panel or if your card has a seperate software for configuring your card but I think the only thing that might disable the left speaker has to be the balance control in Window's sound control or the seperate software.

There could already be a problem with the speaker jack, if only one channel is consistently giving no sound on your system.

Try turning the male (connected to speaker wire) jack and you might hear a static crackle while doing this. If you get both channels to produce sound this way, you already have a failing audio jack, and may need replacement later on.

Hope this helps.

Sounds like the cords that are going into the PC/system have static. Remove the cords from the speakers and simply put your finger around the jacks to remove static. Push the cords and the jacks back in and switch on the speakers. Then twist the volume control, turning it up loud and then low, then loud and low again. That should cure the problem as it removes static that gets built up over time. Either that or your speakers could well be damaged.

Take your fist and cram it up your ***.

It's less common for one of the speakers to go bad in a set of headphones. It's possible - but there are more common problems that will cause this. I assume you have tried the headphones on another device to rule our a problem with the device you are currently listening with and using the other device, you still only hear audio from the left speaker.

The wires in the cord that connect the plug to the headphones are very thin and are susceptible to breaking. The most commmon place for these wires to break is at the point where the cord is flexed or stressed the most. Those points are:

1. Right at the plug
2. Where the wire enters into the left and right speaker.

There are occasions where I have seen the wires become unsoldered from the speaker terminals within the headphones themself.

What You Can Do:

1. While listening with the headphones, try flexing the cord back & forth at the plug and where the wire goes into the right speaker. See if the audio will come back and cut out again.

2. What I have done is cut the cord about 3" back from the plug. Go to Radio Shack and purchase a new plug and install a new plug on the cord.

3. You can also take the headphones apart and cut a few inches off the cord where it connects to the right speaker and reconnect the new end of the wire to the right speaker. The goal is to cut away the bad part of the cord and re-attach the good part back.

4. You can try to replace the entire cord but I haven't been able to find replacement (THIN) cords too easily.

Good Luck,
