Chosen Solution
The left bud of my Sennheiser Earbud Neckband headphones (linked below) snapped off when I accidentally stepped on the cable, leaving just the thin red cabling inside the headphones holding the earbud to the rest of the neckband. It snapped directly above the earbud, which is connected to the green cabling on the left side. Finally, the thin red cable broke, leaving me with a single earbud and a detached “floating” neckband + other earbud. Any suggestions for how I might be able to fix it? I essentially need to bridge the gap of the thin red cable inside of the headphones. I wouldn’t be surprised if it’s unfixable, but would love the iFixit community’s input. http://www.amazon.com/Sennheiser-PMX-686… Update (05/17/2016) Picture of the damage is attached here. As you can see, I did attempt to glue the pieces together, but couldn’t find a suitable clamp and thus was not able to provide a strong hold.
I had a similar problem. Epoxy doesn’t stick well to plastic, so I used Plastic Surgery Super Glue which was suggested by my local hardware store. The glue is not as strong as epoxy, so you have to use more of it. For clamping the pieces together I used Hobby Creek’s Mag Hand Professional with the two large clamps that come with the kit to properly grip the earbud and head band instead of the default small clamps. To remove the brittleness from the small plastic pieces floating inside the ear bud side of the ear phones, I removed the small Phillips screw from the glossy plastic near the ear bud, then used a Jimmy hand tool to separate but not remove the glossy plastic to remove the broken pieces. Then for 5 minutes I carefully positioning the headband and earbud in the clamps and finally filled the low viscosity glue though the rectangle hole created by removing the Sennheiser logo grey plastic piece. Loosen the Phillips screw
Jimmy the glossy plastic at the top of the ear bud
Remove the Sennheiser logo grey plastic piece also with the Jimmy tool
Jimmy the glossy plastic from the bottom of the ear bud
Now you should have enough play to remove the broken plastic pieces
Remove the broken plastic pieces and then put the Phillips screw back on to restore the original shape
Take your time adjusting your clamps, repositioning the magnetic bases, adjusting the goose neck to get the earbud flush with the neck band. Make sure there are no gaps looking around it from all angles
Fill plastic specific glue into the rectangle hole revealed by removing the Sennheiser logo grey piece
