I have a pair of Bose QC20i noise cancellation headphones. When they were new, I could turn on the noise cancellation switch without the jack being plugged in, and they worked fine.
Now, they produce a noticeable feedback sound when not plugged in. This can be altered by touching the tip of the headphone jack.
When plugged in, the feedback goes away, but they produce a hissing sound in the left ear. Sometimes this hissing replaces the feedback sound mentioned above.
However, when music is turned on, even at a level which is inaudible to me, they seem to work fine.
I bought them new only a few months ago, but the purchase was on ebay so Bose tells me they will not honor the warranty.

Does this sound like something I could try to fix myself?
Any hints on troubleshooting would be appreciated.
Is this a good question?

Just cause 3 download free torrent. Same issue here. Left ear static when it used to be a quiet heaven.
Unrelated people telling the same story seems like a design or component issue. I treat this earphones carefully so it is not user abuse. Would Bose offer a solution or should we start looking for other brands and/or options?
I have the same problem. I got it almost 2 years ago. Now the noise cancelling feature seems to cause me lots of trouble as I cannot enjoy the quiet time as I used to. Is there something wrong with it? How come we all have the same problem? From this perspective, Bose noice cancelling earphones do have flaw design issues. How are we going to deal with it?
Bought mine QC20i just a week ago, used them every day since and they worked fine until yesterday with astonishing noise cancelling effect. But yesterday there started coming a 'white noise' in my right earphone, didn't matter if it was plugged in to a sound source or not. It has gotten increasingly worse and today also really loud booming bass rumble in both earphones, but worse on right, when for example a car passes by on the street when previously I wouldn't hear the car thanks to the noise cancelling. Don't know if there's any way to 'reboot' the earphones. Or if they just successively broke down after one week.
Mind you, this isn't at all related to whether they're plugged in or not.
i had mine for only six months before they began to hiss in the right ear. i called bose and they told me to send them in for 'replacement' .. but when i got them back, same problem *and* less effective noise cancellation when in the cancel mode. i called again. i was told that this time they would be replaced instead of repaired. not sure if replacement very happened but upon receiving them back a second time, they were now not hissing but the noise cancellation no longer works half as well as it did originally. not at all noise cancelling any longer. i thought perhaps they had changed them deliberately or something.
very discouraged and a little mift as they are expensive and i take very good care of them. not sure where to go or what to do at this point..except dissuade others from making the purchase until bose gets its act together on these things.
I have exactly the same issue. Static type crackling in the left ear. Seems to work fine for a few minutes when first plugged in and then nothing I can do can make it work again.
In answering this question I'm assuming you have bought headphones recently rather than a new Mac.
There are very few headphones fully compatible with the Mac OS - probably because the makers haven't provided suitable drivers for their products. This issue, not necessarily exactly the same symptom as you have, has cropped up before in these discussions. Check whether the package claims compatibility. If it does then you can start looking for reasons for the problem.
If it's a new Mac, is the headphone driver suitable for Leopard OS?

So its been about month now and for some reason. When I launch game or move my mouse over something (for example on YouTube when you scroll down on the page) there is a very high pitch noise that emits from the headphones it does this with all sound devices and I have no clue how to fix it! Specs:
Intel I-5 4570CPU @ 3.20Ghz
power supply - 430W
Gtx-660 2gb
8gb RAM
On board sound.
I hear a buzzing from my headphones on max volume that is a bit strange (not typical of max volume sound) but I can deal with it. But when I launch a game even with NO sound AT ALL no sound devices enabled at all. It lets out a horrible EEEEEEE sound and when I cap frame rate to different levels it changes in tone and type of sound. Ive tried everything you can imagine I cant find anything! Its not as bad in the back off the computer but still not near acceptable directly to motherboard sound but people on the other side of Skype get annoyed when I cant play games with them because all they hear is a screeching noise. Ive been trying for a month to fix this and I have no clue what it could be.
I have tried getting 2 different sound cards getting 600W power supply sending it back to cyberpower pc and getting a new motherboard. Ive tried everything software, taking out the graphics card entirely. Moving it around to different PCIE ports editing BIOS (it still makes the noise while in BIOS) changing internet cables. Trying new mice new keyboards new headsets everything. I thought it was a short on the motherboard but how could it be that when I get a new motherboard the moment I turn it on its still there? Any help would be appreciated.

This is the sound recorded from my phone being held up to my speakers on my headset.
High Pitch Noise Sounds

You turn on your PC, start up a particularly taxing program, and then—you hear it. A high-pitched sound emanating from somewhere as if your ears are ringing. You're not going crazy, it's coil whine, and it can come from a number of components in your computer.
High Pitched Noise Through Headphones
Coil whine, as Linus from Techquickie's YouTube channel explains, is a phenomenon found in a lot of technology today, but especially in video cards. It usually occurs when a component is working really hard and begins to vibrate, emitting a high-pitched noise in the process. This is pretty common when playing games as they tax your video card the most for substantial lengths of time. Additionally, games or other graphic intensive software will tax your video card at different levels, causing a variety of high pitched sounds to occur. If you're playing or working with speakers or certain kinds of headphones, it could become pretty annoying.

What can you do? Well, the unfortunate truth is that once you've got it, you can't really get rid of it. Your best bet is to prevent it in the first place by reading reviews and researching which products tend to have the most coil whine. So before you jump into buying that delicious new video card, be sure to check that it doesn't also come with some distracting coil whine on the side.
