Step 2: Take Them Apart

Pull the blue cushion off the earbuds - this'll be replaced using regular foamy-type earplugs.
<p>I made mine by freezing the foam plugs first. Even without getting them wet, they get pretty hard. Makes it real easy to cut them with an Xacto and then I used a Dremel with a small drill bit to cut a hole through the foam while still frozen.</p>
WORKS GREAT!!!!!!!!!!!! the only problem was putting the tips on the speakers :D i had to stretch them out with scissors and at the same time insert the earbuds D:
That's not how noise-cancelling headphones work. Do you really think they charge $200-$300 for some extra foam? It's a nice idea, but it should be labeled &quot;Quieter Headphones.&quot;<br/><br/>See <a rel="nofollow" href="http://en.wikipedia.org/wiki/Noise-cancelling_headphone">Wikipedia</a> for more.<br/>

Actually its noise isolation, not reducing. Noise reducing can be the same as cancelling.
Granted low end cheap ones are called all kinds of things to make them sound like noicse cancellers, though sony walkman ones for phones are amazing quality, the plugs works perfectly due to the size variety, using these buds and some form of sound canceller would probably work for those that don't like using overhead ones... Such as my big haired self...
For quite a while, I used the following combo on turboprops:<br /> <br /> 1)&nbsp; Rat Shack in-ear isolating headphones, which gave better isolation than the JVC Marshmallows you used but with effectively no bass response.&nbsp; I used Marshmallows everywhere else - less isolation but superior sound.<br /> <br /> 2)&nbsp; Philips HN100 circumaural active noise cancelling headphones<br /> <br /> I'd put the buds in, and the HN100s over them.&nbsp; Music to the buds, HN100s disconnected but with power on.&nbsp; ANC works better than isolation at very low frequencies (jets/turboprops), and passive isolation tends to work better for highs.&nbsp; Best of both worlds, just looks a little funny.&nbsp; :)<br /> <br /> I tried to do what you did here 3-4 years ago but failed as I couldn't figure out a decent tubing solution.&nbsp; I never thought of using heatshrink, it's a perfect idea!&nbsp; Note that due to the form factor of the Marshmallows, it may not work with the old HN100 + buds combo.&nbsp; (I don't remember it working comfortably before, the Rat Shack buds stuck out from the ear less.)<br /> <br /> Couple of tips from my experience:<br /> 1)&nbsp; Make the heatshrink extra long and trim it down later, after you've put the foam on to determine its required length.<br /> 2)&nbsp; Before trimming heatshrink or trying to put foam on, MAKE SURE it's cool.&nbsp; Freezer for 15-30 sec works well to ensure this.<br /> 3)&nbsp; After punching the hole in the foam, slide it over something that it fits over easily and is solid and squish it down around that item.&nbsp; Believe it or not this will actually make the hold larger as soon as you remove pressure.&nbsp; It makes it easier to slide it over the heatshrink, especially the base where it's shrunk over the end of the bud.<br />
It doesn't appear to be possible to edit my post:<br /> <br /> I think I used a 1/8&quot; punch.&nbsp; I'll need to check.&nbsp; I got a &quot;hammer style&quot; punch set at an arts and crafts store.&nbsp; It had three sizes of punch, ???, 1/8, and 3/16 I think.&nbsp; 3/16 proved too loose, 1/8 was perfect if you used the trick in my previous post to get it to go over the base of the tube.<br /> <br /> I now have better isolation than the old Rat Shack buds, AND they sound better than the Marshmallows did before.<br />
I have done the same thing with both some less expensive Koss and my decidedly more expensive Shure in-ear phones. I have found the easiest/cleanest way to make the hole is with heat. It doesn't take much. Get an appropriate sized piece of metal for your 'buds (a nail, nailset, punch, soldering iron tip) and heat it up. A lighter is messy (carbon build up) but works. I like a small electric soldering tip (or put the nail in your iron if yours has a removable tip). I make a bunch of spares at a time. <br><br>I wish I'd thought to 'ible this !!
i was lazy, paid a little bit and got these!!! they are awesome! <br>unfortunatly an ebay item... <br> <br>http://rover.ebay.com/rover/0/e11030.m43.l1123/7?euid=d3c444df82d04e04af30d33d739d26ff&amp;loc=http://cgi.ebay.ca/ws/eBayISAPI.dll?ViewItem%26item%3D250817321899%26ssPageName%3DADME:B:EF:CA:1123
Thanks, I've been having the problem of my ear buds falling out constantly, this idea saved me from having to buy a new set, they stay in much better now. Cancelling, isolating, who gives a $!@# what its called, they help them stay in and give good bass response that's all that counts. Nice Instructable, I love anything that saves me money. You could have been a little more clear on the use of the shrink tubing, but I didn't use it anyway, and I super glued the foam directly to the post, works like a charm.
Where can I get a pair of folding scissors like those. They look great.
It's a mini-leatherman tool. you can get them with pliers now too. I wouldn't be surprised if Walmart had them in their sports dept. very handy.
it's a micra, right?
Damn, beat me to it. i was thinking about doing almost the exact same thing that you did.
Their earphones not headphones. Earphones are what you have there and headphones are what you put on your head and not in your ears.
This should be labelled, "Noise Isolating" instead of "Noise Cancelling". "Noise Isolating" earbuds are passive -- they block-out ambient noise by sealing out sound "Noise Cancelling" earbuds and headphones use active electronics. In simple terms, they detect ambient sound with one or more microphones and create the inverse frequency of that ambient sound to cancel-out the ambient noise.
It's sort of a joke: "...Poor Man's" . Since we all wish we could afford the nice Bose noise 'canceling' headphones the best we can hope for is to at least be able to call these one's 'noise canceling earbuds' - can't we? Your right though - there are not active components or 90deg out-of-phase stuff happening with these.
I can see where he's coming from, only problem is hardly anyone knows the difference and what term to use where.
hay I have the same earbuds
How is this a robot contest entry???
technically, it would be a cyborg contest entry. (he is putting electronics INTO his head.) :)
No, it doesn't count.
Yes it does - this is the coolest robot ever....I'm gonna WIN....
....I'm trying to get them to remove me from the contest....
It isn't I think people are just ticking it as they publish.
you should add these instructions to your other instructable video, and delete this one, you don't have to have two...
