I have had problems with my headphones as well from Bose QC3's. They will give you a new pair for $100, even if it has been longer than a year...

SOURCE: Less sound on one ear than the other

Yeah, based on all of your problems, i would safely say that you have a blown speaker. Call up Bose at 1-800-999-2673. If the headphones are under warranty (1 year) they will replace them for free. If now, they will charge you $100 for a replacement pair, which is quite a deal considering that the headphones cost $300.

SOURCE: Bose headphones only working on one side

You might want to look at my Tip on replacing plug/cable on headphones, it might solve your problem.

SOURCE: Bose Headphones only works on left side.

Have same problem. Play with the plug in the socket. I'll bet it you can occasionally get both working. Not a solution since it probably won't stay working. I have an old plug and it fails too. I'm afraid they did't make their plugs to the right tolerances. Used to work once. Annoying for this expensive a headphone.

How to replace ear cushion on bose QC 3 headphone


The ear cushions are held on the earcup with six snap fasteners, three on each side. To remove the ear cushion, simply pull it away from the earcup carefully so that you do not break the plastic snap tabs.

It should not be necessary to pry the ear cushion off with a sharp object, but if you do, be careful. There is also a thin gasket seal between the earcup and the ear cushion, take care not to damage it.

If you need to replace the ear cushions with new ones, they are available from Bose for $35/pair.

Can bose QC3 work without noisecancelling/battery?


No, the audio input must go through the active noise-canceling circuits that drive the speakers in each earcup. The noise-canceling circuits require a charged battery to operate. Unfortunately, there is no way to bypass these circuits and drive the audio input directly to the speakers.

Bose QC3 makes a high pitch noise when i press it against my ear


The design of these headphones includes a microphone on the outside and on the inside of each earcup. The outside microphone detects outside noise. The inside microphone monitors what you are hearing and when it detects that the outside noise is present inside, the active noise-canceling circuits remove that noise. This happens fast enough that you perceive a siginficant reduction in the outside noise getting to your ears.

The airspace inside the earcup is a tuned chamber defined by the foam in the ear cushion. This is important because with the inside microphone in close proximity, but at a 90-degree angle to the speaker, the circuit must be designed to eliminate the normal feedback that occurs. When you press the earcup close to your ear, you are changing the size and shape of the air chamber inside of the earcup thus directing more of the speaker sound toward the microphone than the design can compensate for causing audio feedback to occur. You are hearing that feedback. Removing your hand from the earcup should restore the shape of the air chamber allowing the circuits to return to normal operation.

If the feedback occurs too easily when you are NOT pressing on the earcup, then the foam may have weakened/deteriorated and it may be time to replace the ear cushion.

On my QC-3 headphones, I can cause the feedback squeal in both earcups, with the left earcup being more sensitive to the shape change than the right.

Only the left earcup works, even if i change the wire, its the same. but noise cancelling works on both.

Intermittent Crackling noise in the right headphone


Hello Rachel, I use my QC3 for 2.5 years Mon-Fri for 3 hours a day. I have the same problem when battery is weak and/or it is cold outside. The cracking nose stops for me if battery fully charged. This is known problem andBose put it in the manual.
