SOURCE: I have lost sound in the left earcup of my Bose

The solution to this problem is not for the faint hearted. You will break your headset, you will void your warranty, and you quite likely will end up with a non-working headset. You will also have to solder very small electrical components.

I also had the left channel audio not working, so the first thing to do was to take apart the headset.

Step 1. Remove the battery. Remove the two tiny screws from under the u-shaped plastic piece that holds the earpiece to the headset. You will have to pop out the end furthest from the audio jack. A #0 phillips is needed. Put the tiny screws in a safe place.

Step 2, Break the silver cover free from the black plastic earpiece by sliding a flat blade screw driver down between the joint towards the bottom of the earpiece. Be very careful not to insert the screwdriver blade too far into the earpiece because the circuit board is just inside. For some reason Bose decided to glue the two attachments for the bottom of the silver cover to the earpiece.

Step 3. Unscrew the 3 screws holding down the circuit board and put them in a safe place. Gently pull up the circuit board about .5cm. Look at the audio jack, the tab on the circuit board on the bottom right is the left channel audio. You can try to reflow the solder at this point on that tab using a 25W iron. It didn't work for me, but if your connector is not as bad a mine, it might work.

Step 4. Remove the solder from the 4 tabs holding the audio jack to the circuit board. Remove the audio jack from the circuit board (this is hard and accompanied by much cursing). Try not to overheat the board and lift the lands. Use a pliers to pull out the contact for the left audio channel and bend the jack contact out 1mm or so. Insert it back into the audio jack. Get your audio cord, plug it into the jack and check and see if you have continuity with an ohmmeter. If it all checks out, continue on.

Step 5. Resolder the audio jack back into the circuit board (also accompanied by much cursing). Screw the circuit board down. Put the battery back in and see if everything still works. If it doesn't, check to see if you broke the fine wires just above the audio jack on the circuit board. They run to the other earpiece through the headset.

Step 6. Reassemble everything and see if it still works. If it does, then congratulations and enjoy your restored audio. If not, open it back up and look for broken wires.

Disclaimer: This solution will likely destroy your headset. Proceed only if you have experience working with modern surface mount parts. I am an electrical engineer with 30 years experience in troubleshooting and repairing electronics and it still was not an easy fix. Total time to repair was about 4 hours.

No, Bose doesn't cover any damage done to products that is any fault of the buyer. You might be able to if you contact a Bose retailer and special order it through them. Just a note, it will cost you more for the new speaker due to it being a special order. Probably around the lines of 40-50% of the original sales price (which is outrageous). If I were in your shoes, I'd try to find the same unit on craigslist or Ebay.

SOURCE: Can bose QC3 work without

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.

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.

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.
