Chosen Solution
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.
Hie Friends I came up with a good news My qc20i right side earphone was making craking sound while playback and when I on the noise canceling button it not canceling full from right side , m very music addicted and I prefer only quality in Meanwhile I was so depressed and researched all over internet about this problem but I got no solving way then I research on earphone mechanism then I got an idea THEN IT WORKS PERFECT that is Remove your earbud ( white bud ) which side is not working then clean it with tooth brush carefully then blow air with mouth in to the earphone tightly and make sure that air going through other side ( metal mesh ) of the ear phone then repeat from mesh side and let the air from budside way , repeat that 2 times and then connect the earphone to your device and check Hope it will work Worked for me All the best
I don’t think so. The “static” is most likely caused by grounding problems in the plug, control unit or wire. Working on headphones that small requires special irons, & solder, with lots and lots of practice. It’s not like fixing a lamp cord or speaker. I don’t know how you would get into the unit to repair it without leaving it in a worse state than it is now. If this answer is acceptable please remember to return and mark it accepted.
I bought mine off ebay last year, but never got to use them for 4 months due to working away on nights. Same problem with crackling in left set. The guy who sold them obviously knew this, but my mistake. Phoned bose. They said never heard of a problem like this. What lies people tell you in order for a sale. Looking at this and other forums about same problem, bose obviously know about these issues. Well I have all bose systems in my home. No more though. This will be the last time I ever buy bose. After service is crap!
I fixed this by (from the sound preference pane) deselecting my Bose Quite Comfort 30’s from being the system default microphone, and the default sound output device, and then re-setting it as the default sound output device. This appears to have disabled the microphone and fixed the static.
this doesn’t seem to work for me. when i turn the device on it is often fine, but as soon as it comes near a plug-in there is an increasingly loud log humming sound. i’ve tried the above recommendation with different cords that elicit the crackling sound, but after doing it repetitively the low humming sound continues.
I have the quiet comfort over ear noise canceling headphones. Just a few weeks ago, I noticed static on the left ear. Plugged into the PC, plugged into my phone, didn’t matter, static on the left. Remove earphone cable, still static on the left. Turn off the noise cancelling button, static stops. Replaced battery, static on left side still there. As others have indicated solution is easy Remove the ear cup, Remove the felt piece, I noticed mine had moved, and wasn’t in its proper place. I then blew on the mechanism a bunch of times, reset the felt to its proper position, and whamo, no more noise. You could also try the knife method to increase the space which you can clearly see has only one way to do it. But this isn’t a Bose problem, this is a long term use problem. Just clean it people, and whamo, you have working headphones again.
Yep, I had the same problem. Send them back, they will break soon, mine did.
I started experiencing the same thing on my 3 year old QC15. I unplugged the cord from headphone and plugged it back in securely. It fixed the problem. They also include an extra plug just in case the current one is actually broken . Hope this helps.
Hi Joe, To fix your problem on your Bose QC 15, you have to change the battery. To do that there will be a tab on the left side of the headphone, open that and switch the battery.
Try a different audio app. The issue may be in the app and not the headphones; Unpair your headphones from your device, and then pair them again. By the way Bose QuietComfort 20 is the best noise cancelling earbuds.
Hi Joe, My right side had a very annoying buzz. I did like you said but I had to pry up the metal piece pretty far to get the buzzing to stop. But it did! I bought these used and they had buzz when I got them so I am happy to get them fixed! I think what happened is the previous owner must have pressed in the center of the ear cup accidentally and it pushed the metal thing to close. Anyway I am grateful!
Hi guys. I have changed my Q25s for the new Q35s A few months back. What a difference.
Hi guys Well the new Q35s are a lot better, so I thought!! Anyone who has the new ones Q35s have you gone out side the home on a windy day, try it let me know if it’s just mine. On a windy day the noise coming through head set is deffening. A pain too.
I had the intermittent crackling/scratching noise on one of my earpieces. After taking apart, I’ve found a small potentiometer that when tapped, made the sound go away. I’ve given it a tiny turn and the cracking has now gone away. I believe this pot is wearing out and causes the scratching type issue. It makes sense as the noise is similar to a worn out pot on a hifi.
If you have all your pieces try cleaning the speaker piece with like hand sanitizer or something the kill germs get a cotton boll wet it with germ killer supply and blow it once done put the pieces back on then it should work it will also work with a remote to but barely put germ kill on it
