How to fix 'static' noise on Bose QC20i Noise Cancelling Headphones?

Text:

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.
