It does not fit Iphone 
2009-06-22
As others have said here it does not fit all models. I decided to buy regardless the review as I saw on their website it had the original iphone 8GB as supported. To my disappointment the ear jams are too big to fit the iphone earbuds. I tried taping it to be able to use it but it just looks stupid. I though about gluing it from the inside but I don't want to damage my original earbuds.
Solid upgrade to stock apple headphones 
2009-05-27
These are a pretty solid upgrade to the stock headphones that came with my iPhone 3g. I run a couple of miles a day with my phone, and these guys eliminate much of the problems I was having with the headphones popping out of my ear when I run or would start to sweat. They also are much more comfortable for daily wear around the house/office and really help to isolate sound and help me focus.
Now, the down sides. Despite what some folks have said, these do not fit onto the headphones for the iPhone 3g. The 3g's headphones are slightly different then the older iPod headphones these were designed for -- the hard portion where the cord comes in blends into the headphone, rather than the cylinder and 90 degree connection, and they are slightly smaller. However, I managed to solve the problem by rolling a very small cylinder of sticky tack around the iPhone headphones. The adapters now stick on very nicely.
I found the ear nubs that came with the headphones to be very thing and not feel like they were going to stick to my ears. Thankfully, I had another two sets of broken Griffin headphones with similar, but heavier duty rubberized earbuds. After switching this out they head phones stay in place much better and feel much sturdier. So keep in mind, that these still suffer from many of the Griffin quality issues, but a little work makes them quite nice.
Clearly, this isn't a great option for audiophiles and it dulls higher frequencies quite noticeably. Also, with the adapters on, my svelte headphones now are much larger and look a little like something Frankenstein would use. But for the price they prove to be an acceptable addition.
These are cool!

These are cool! They snap right onto your headphones, and vastly increase the bass, and reduce outside noise. Well worth the money. Only one complaint- the first time I bought these, they came with a second, smaller set of covers that fit regular round earbuds. I have the sort of oblong or oval shaped headphones, and that is the kind that fits. But I also have the round earbuds, and they do not fit. Bummer. The little case that comes with it and the spare covers and rubber pieces is a very cool bonus. I highly reccomend these ear jams, because they make the sound much better, they are inexpensive, and they last a long time. I will definitely purchase another pair when these wear out!
Does what is claims to 2009-04-25
The product does what it claims to. Unfortunately i did not read the description carefully. They did not fit on the earbuds with my new iPhone 3G. I added a some tape to my earbuds and now they fit. They definately stay in the ear..i shook my head violently and they stayed in. The mid & high tones are not as crisp or loud. They definately added a lot of bass...so much so that i used the EQ setting, "reduce bass". I was also able to listen with a lower volume setting. I gave the product a 4 star because it did what it claimed. However, I would not buy another pair becuase i miss the mid & high tones. I guess i'll just have to fork out the extra cash and buy a way more expensive set of earbuds with microphone to work with my iPhone.
Griffin Technology 4039-EJAM EarJam Earbud Sound Enhancing Covers
Horrible 2009-04-01
Do not under any circumstances buy these things!! They do not even fit onto the Apple earbuds. And as far as sound they make the earbuds sound like they are in the other room. I threw them away immediately.
Function as intended 
2009-03-12
Griffin EarJams revolutionize the iPod earbud by providing a more custom fit to your ears. The result is greater comfort, improved sound isolation from external noise, superior sound quality and volume. EarJams easily snap onto your Apple earbuds. Each set of EarJams comes with three sizes of earpads to give you a snug and comfortable fit.
Great for my ears 2009-03-08
It may be the shape of my ears, but ear buds fall from my ears very easily. It's quite frustrating. Even if I just shake my head, at least one of them falls off. I was looking for a replacement headset when I saw these covers.
The Earbud covers fit comfortably in my ears and make the sound clearer. They don't fall off very easily, so they're just what I was looking for.
They come with three pairs of rubber ends, for three ear sizes, as well as a small protective zipper-bag. Great value.

Great ear buds 2009-01-19
The buds were shipped and received in very short order. They work great with my Iphone.
Good as described, except... 2009-01-15
Most of the reviews are echoing the same things, namely more boom, fits relatively well and they're cheap. All true.
Recently, however, Apple changed the size of the earbuds included with the newer generation Ipod's. I have the Ipod Nano Gen 4 and the Shuffle Gen 3 and they don't fit. My wife has the Nano Gen 2 and it fit hers. She likes them and thanked me for them... :)
