Earbud EQ

I'm not sure I specifically cut that freq but I do test my mixes in four different sets of headphones/earbuds.

First thing I would do is be sure that you aren't destroying the careful mix you made for ear buds. Find a master album that you admire for both its content and the high quality of its sound that has a full range and see how it sounds on the buds. Do not do anything to the sound you get. This will be your reference in testing out audio gear.
 
If you hear problems it should be in the gear not in the album. The over all idea is after listening you should know where you stand with the buds. If the album sounds good on the buds you know its the mixes you are doing that have the problem. If on the other hand the great album sounds bad then you know if you adjust the mix it will hurt it. 
 
Personally, I think you should ignore ear buds. 
 

No, if it was mixed and mastered correctly, it will play good on your ear buds and all other sound systems

Jeff, I want your magic sauce. I can't get the bass to sound good on ear buds. On all my stereos the music is AWESOME! but on cheap junk earbuds it just disappears. Nothing I can do about it. Only thing I've considered is using an octave tool to duplicate the sound up an octave... but I've never gone that far.
 
I've definitely pushed the bass to the top of my comfort level on all my mixes to try to compensate.

I've always believed this to be true, so it's what I always aim for in a recording.
 

I remember listening to a mix on my crappy Bose laptop speakers and getting depressed at how boomy the bass sounded and how far back the mids seemed. Then I listened to a Donald Fagan track on the same speakers and I heard the same problem. So I stopped worrying about it.

Remember that earbuds are not all the same. There are cheap ones (quality of construction) and there are nice ones. I have compared a few side by side in my MP3 player and there is a big difference in their overall frequency responses.
 
 

 
If you're optimizing specifically for stock Apple earbuds, here's what you're up against. 

Now I'm depressed I didn't know they were that bad. I don't think I have ever used an iPod. Now I know why.

You do know you can wear any headphones you like with an iPod right 

Yep, you can even use your studio phones.....you might have to take your protective case off, though.

Funny and sad but true: Apple's own spec sheet claims 20-20KHz frequency response!

Yes..but you must take NOTE of the fact that the don't give you +/- ratings....it would be like +7/-30

They do respond to those frequencies...they just don't do it FLAT or well...so, they are "TECHNICALLY" correct...

The reason I posted that graph was to illustrate that it isn't really even possible to compensate for those earbuds' spectral deficiencies. You'd have to add 20-30dB to the low end, which would a) distort the buds something awful, and b) make it nearly-impossible to play on a broad-spectrum system. (Taking a little off the top probably wouldn't hurt, though; the better headphones of the world tend to be almost a mirror-image of that picture on the high end.)
 
There's a reason why people's eyes go wide and jaws drop the first time they put on a pair of high-end headphones. It's not because expensive cans sound great, but rather that they're simply hearing, for the first time, what the producers intended all along.
 
I think of it as an easter egg. A hidden surprise for anyone willing to go looking for it.

I like the EP-630 ear buds.
 
I have basic black but they are now available in 5 different colors.  AND..... more than that.... they boast a frequency range from 6hz to 32khz...... yup... you read that right.... Up in the dog whistle range all the way down to seismic activity range. Certainly the color would affect that range a bit don't ya think?  (sarcasm in ten did)
 
Seriously ......  these are noise reducing with fairly comfortable rubber ear cups .... they come with 3 different sized pairs of cups so you can choose the right size for you. I have found that I can comfortably wear these almost all day while driving or working without discomfort. I will sometimes wear them while cutting the grass with no music playing rather than grabbing the foam ear plugs I would normally use. 
 
In the studio, I do not use them for mixing or mastering. But I have used them a time or two to track a vocal. I think they shine in this role since the mic bleed from them is non-existant compared to normal headphones.
 
http://www.handspreca.com/creative-labs-ep-630a-noise-isolating-earphones.html  I buy them from Amazon and normally can get them in the $15/pair price range. I normally buy 3 to 5 sets at a time since when I work and use them they tend to have a shorter life than if I took care of them and only used them in leisure time pursuits.

I have found that there are different mixes for regular cds and itunes. Mostly because of the platform being mixed for. Hence the difference in sound for iPod and such

This sums it up.
