The wire from the box to the earphones got caught on something and tore in half. I want to open the box and resoldier the wires to the box
Repair guides and support for headphones inserted into the ear or ear canal, also known as earbuds, earpods and earphones.

Connections for BOSE QC20
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!
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 :)
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 ?
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.
Fixed one with audio jack ripped out of casing today. There are 5 pads
M+=Mic+=white inner wire
M-=Mic-=dark green outer wire (Other pics that I’ve seen looks black)
Here is a pic (not mine)
Mine had plastic covering all the solder junctions. Cleaned it off with soldering iron+xacto knife. Careful to not melt off the stud at the red arrow
Soldering not so easy. Easy to have a stray strand (if mic + and - touch, then no mic and audio controls) Best have micro soldering equipment. Wires gets twisted upon assembly. and the whole clip has to rotate under the board to get into the body. I thought about removing the board but the flex cable at green arrow gave me caution.
Coated the solder junctions with rubber cement (or anything to insulate and secure it that doesn’t expand or shrink)
