Question about Bose QuietComfort 15 Headphones

Rattling in left earcup

Hi, I recently purchased the Bose QC15's and noticed that there is a rattling noise coming out of the left ear cup. The rattling noise sounds as if something is loose (the driver for instance). It's not a high pitched crackle, rather a sort of loose rattling sound. Has anyone experienced this? I don't have warranty (bought it off ebay new factory sealed), but can confirm it's legit. I've searched the internet for answers but have come empty handed. Please help.

Sounds like you have blown out the cone on the speaker. Have you removed the covering to see if the speaker in that earphone is intact?

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 triport ear cups padding burst open how can i

May be a little late for you, but both of my pads burst open, and after trying in vain to tell Bose how **** their products were (because they are) I decided to fix them myself rather than give Bose more money, allowing me to keep using my headphones until I buy another pair (from another manufacturer). Anyway, you can buy new pads off eBay, there seem to be a few on there, or, to fix yourself as I did, you can just pop the pads off (they clip on), then take a needle and thread and stitch the pads back together at the seam. This is a bit tedious, and you obviously have to jam the foam in there while you're doing it, but mine are now better than new (because my threads are stronger than the apparent **** glue that Bose uses). Takes a little time if you're not a big sewer (which I am not) but it's well worth the effort in my opinion. Gives you a great like-new pair of headphones...until the next thing breaks, and trust me, something will, it's Bose!

SOURCE: I lost the sound on the right ear of my bose

This may be your headphone jack (what you use to connect it to your ipod or speakers ect.). check the connection there, and if you see the wire became loose near it, that is most likely the problem. You can fix it! With a new headphone jack (available at the Source or Radioshack or other stores like that), and with some manual soldering (it's not too hard, I fixed my myself and I havn't soldered before.) you'll get those headphone to be as good as new. here are the steps to fix this problem.
1. cut your old headphone ******** and strip the wires. you should see two wires; one copper wire and one coloured wire (green or Red) on each cord. there is a total of 4 wires, two per cord.

2. Tin coat the wires. this means to burn the wires a bit (with the soldering iron) and put solder over them. this gets rid of the coating that is on the wires to stop them from shorting out in the cord and helps conductivity when soldering them onto your headphone jack.

3. there should be three holes on your new headphone jack. there should be two prongs left and right of the part you plug into the machine, and there should be one connected to the part that holds the wires once done.

4. connect the coloured wires (red and green) to the left and right prongs of the new jack and secure with solder. These are called the live (or hot) wires because they are the ones that send the signal that makes the sound.

5. connect both of the copper wires to the other hole and secure with solder. these wire are both ground wires, which are very important.

6. by the end, you should have connected four wires. two to the seperate prongs, and two to the third ground hole.

7. test your connection by trying to use your headphones. if it does not work (which may happen, don't get discouraged!) check your soldering. if it is touching any metal it shouldn't be, that means you have created a short circuit. simply burn off the solder (with the soldering iron) and try again.

8. keep trying until you get sound. good luck!

9. Once you get sound, you may want to secure the soldering job. you can either use two part epoxy and put this over your work, or you can tie a knot before you put the cover on you headphone jack. either will work just fine. Also, there sometimes are two metal protrusions that you can bend with plyers to help hold your chord in place.

10. enjoy your fixed, good as new headphones! Enoy hope this helped.

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.

Phones get a peersing screach; itgets louder when you press the side where the on/off switch is


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 significant 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.

You are hearing that feedback.

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.

It is probably time to replace the ear cushions. If so, they are available from Bose for $35/pair.

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.

Just recieved a pair of qc15's after the first use the right ear cup will crackle intermittantly, building up then dropping out, it does it randomly


It's the EQ of your ipod or itunes that is tripping them up. Apparently there is a 'perfect' EQ to run them on but I'm not familiar with it. Running them with the EQ 'flat' should fix the problem. Hope this helps...

I have had my headsets for 3 years, they work well, I have just noticed that the left ear pad is detaching from the base. How do I get fixed?


The ear cushions are attached to the earcup with plastic tabs that snap into the plastic in the earcup. The lower snaps may be unfastened. Try pressing the ear cushion firmly to the earcup around the lower edge to refasten the snaps. Do not press in the middle of the ear cushion - you may damage the internal microphone.

If this fails, you will need to remove the ear cushion by pulling it off the earcup and inspect for broken plastic where the tabs are on the ear cushion or where the tabs attach to the earcup. If a tab is broken on the earcup, replacement earcups are available from Bose for $35 per pair.

If the plastic in the earcup is broken, you can try to repair it or you can contact Bose about getting it repaired or replaced.

Hello, I just got a Bose QC3 on eBay. It works fine except the cable which is not the original one but a one from T'nB and the left earpiece has a very annoying whistling noise when I press it or even...


i would buy a new ear cup.and a new battery. and perhaps a new cord.
i had a problem w/ my ear cups and i noticed that when i bought the new ear cups the sound was better.
i also read that if the battery got alot of usage (4 plus year) then the whistling noise comes from that. i'm starting to have the same problem. i have had my headphones for a long time. i think like anything else that operates on batteries its time to change it.

Feedback sound like wind noise in right headphone of QC3, starts quietly and gradually gains in strength. Sometimes disappears, then comes back again. No sign of moisture in battery compartment. Any ideas?
