Hi,

I have the connections for the wires which goes towards the earphones. There are total 16 wires which needs to be soldered. If you want the images of the same please provide me your email id and I will email it to you.

Thanks

This is great! But I what's the difference between the first and second picture? Two sides of the part? And you say "Blue & Golden" are you referring to two different wires, or the same one with two colors? Thanks! andreboaretto@yahoo.com.br

The 02 pictures are 02 different sides. 1 side has 8 wires and same goes for the back side. Also wherever i have mentioned 02 colours that means the same wire has 02 colours. They are not separate wires. Hope this clarifies your doubt.

This happened to me too. 2nd time the headphone cord ripped out of noise cancellation box after the cable became snagged. I didn't yank it or abuse it just normal day-to-day activities snagged the cable and pulled it loose. I believe this is really a bad design issue. A jack there would make much more sense than soldered connections. Any ideas how to secure it so it doesn't rip. Or give me a short soldered connection with a jack we can plug into and that breaks away easily without destroying >$200 set of headphones! I'm not an electrical engineer so maybe a jack with 8 wires and 16 connections isn't feasible, but I surely am frustrated by this.

Thank you! Please send me your schematics, and I am going to try to solder it back. terenceswee at gmail.com

Hi, Chris!

I hope you resolved problem and fix your headphones?

I was able open this box - housing is opened only by cutting the rubber sheath.

But I have cutted cable from headphones side(torn cable)

And 6 out of 12 cords I have no idea how where to should be connected(

I would be grateful if you could take a picture or paint contacts connected, because I don't have any idea how!

Thank you very much!

Best wishes!

Me too I would need the wiring schematic of the quietcomfort 20, since I break the earphone wire and i am not able to @%^!* the right wiring configuration. If someone has a picture would be really great.

Did anyone solve this problem? I have the same issue.

I just purchased a broken pair of Bose QuietComfort20 earbuds from ebay. The description indicates that the headphone jack was accidentally ripped out of the main board (with the active noise canceling). The photos from this device can be found here: http://imgur.com/yy0gow6 I was able to open these quite easily. I had to peel off the ends which had a sticker type protection over them and then was able to pry the rest of the case open using a razer blade and another sharp straight edge. So, after opening this up I see that it appears to be some kind of black compound/glue on the connections and it appears to be 11 different wires that got ripped off the board. The real question is, how can I tell where they should be reconnected and how should I go about doing it? Any advice, picture or schematic is welcome!

Feel free to email me if you can help :)

Hi,

I've the same problem of cable disoldered...

yesterday i disassembled it, but i've only 12 wires, not 16!

Maybe it's because i've QC20 earphones and not QC20i (Apple edit)

Anyway, could you send me the pictures of your repair ?

arnaud.rigole@outlook.fr

Thank you in advance!!!

I did the repair yesterday - forget it if you do not have HIGH LEVEL skills in soldering…if you HAVE the skills the pictures above are enought. 4 of the 16 wires are covered inside a coaks-like cosntruct. Mine is working again but it was a pain in the ass.

Chris, would you mind to explain how you opened and closed the box without ruining it? Had a pair with a loose wire somewhere around the strain relief also where some hot glue is on the cable, so pretty much &&^&@@, but I basically Tore apart the box trying to open it. Something bent, and on the side where the traffic awareness button is a little bit torn etc no &&^&^$^ way to close that $@$* again, so TLDR I ruined it.. How the heck did you do it. I'm kind of !#^&@@ that the expensive &&^&@*@ are so impossible to repair on your own without hacking something together to keep them together after opening them.

Cheers.
