"Sugru" (sugru.com) is  a air-drying silicone goo invented by Irish artist and businesswoman Jane ni Dhulchaointigh and a team of materials scientists.

Sugru starts out slightly sticky, like Silly Putty, but after a few hours solidifies into a harder rubbery texture which retains its shape but is still pliable.  It can be used to fix any variety of things, or to "hack things better" as the Sugru motto suggests.

This instructible details how to fix the silicone rings on the earbud headphones that come with the Apple iPhone.

Step 1: Start with broken earbuds

 My earbuds started out in pretty bad shape.  I use them for many hours every day and when driving.

The rubber rings on both sides was separating from the plastic.  That's bad, because obviously it looks bad, but also because the lack of ring leaves a slight sharp edge on the surface which was beginning to irritate the inside of my ears.

Additionally, one side of the earbuds was coming apart, the two plastic parts no longer glued together.

You can see what remains of the rubber from one side in the photo.
At this point I dipped my fingers in soapy water to smooth it out, which made the sugru much smoother and more comfortable in my ear.
I did the same thing with a very small length of shrink tubing. Not as cool or (most likely) comfy as Sugru, but it works great.
haha i did the exact same thing a while back and it works great
You should post pictures!
Pictures! Unfortunately, the band loosens over time, so I have to periodically fix it with the heat gun. I wonder how I could eliminate this problem...
maybe a silicone glue or something?
Very nice instructable... I plan to do this tonight considering I got my Sugru in the mail yesterday. :)
where can one buy this "sugru"?
Please check their site at sugru.com .<br><br>Specifically:<br>https://sugru.com/buy/
Very nice... I plan to do this to my earbuds once my sugru comes in.
This i'ble has shown my why they never have Jane's full name on anything.
Kiteman want sugru.&nbsp; Give Kiteman sugru.<br /> <br /> Give Kiteman sugru <em>now!</em><br /> <br /> (Once they're in production, we should have a sugru-sponsored contest!)<br />
I got mint this morning :D
Ah-ha, so did I!
A sugru contest? That would be great!!
quinted!!!! :P
Here we go again... Sixthed!
more like skipp-ed Seventhed
No one said first so I have the right. =P
kiteman is &quot;1st-ed&quot; because he said &quot;i agree&quot;, then we all agreed with him.... just sayin
Nope, he just agreed, but wasn't &quot;officially&quot; the first to agree with anything. =P<br> <br> <br> he didn't know this chain would happen... lol ;)
Good point. ;)
100001sted because at least that many people would agree.
one hundred thousand seconded
FIRST!!!!!!! what? no one said it yet....
Say folks, has anyone taken their broken earphones into an apple store? They will more than likely be happy to replace them if they don't show signs of abuse. I've seen them do it over and over when I worked there part time. I never saw them charge for a replacement.
my iPhone ear buds don't really fit my ears well, can I use this as a custom mold-to-fit?
thats exactly whati thought of!
OR this could work too. http://www.instructables.com/id/Easy-way-to-noise-insulate-your-earphone/
Wow, that stuff is awesome! I got broken buds like that for a long while now. Awesome instructable, thanks!
Nice. I like the vibrant orange with the white, too.
I wonder if I could make a pair of fitted shoes with sugru...
<p>sounds like a croc to me</p>

Yay I have see that moive!!
make your own silly bandz lol
There was so much of this stuff at Maker Faire North Carolina. I wish I had bought some more. It is pure awesomeness.
Man, why didn't I have some of this on hand when I was repairing my earbuds with hot glue?
Good instructable.&nbsp; When this happens to my earbuds I usually buy new ones.&nbsp; Now I don't have to :)<br> <br> Sugru is really cool. I will be getting some.<br> <br> When I need to make repairs to cables or make my own, I use heat glue or epoxy, with heat shrink tubing.&nbsp; This comes out very&nbsp;rigid.&nbsp; Sugru looks like it will do a better job for all sorts of repairs.&nbsp; Love it.
That looks like brilliant stuff! How hard is it when 'set'?<br />
It's a tough rubber, so very much like the rings I replaced.<br /> <br /> Thicker applications might be good for tool handles, for example.<br />
Sounds like tough stuff, thanks!<br />
