what would distortions sound like? cause my source is my desktop and i get some hiss.... and ocassionally some crackles? but thats even at a normal listening volume. should i change sources or?

update! hiss has stoppped. i simply plugged my headphone into a different jack on the desktop!!! and does it matter that the classical music im playing through them is from pandora? or is that too low quality?

and curious of how long it normally takes to burn in 900s?

I usually burn in all my headphones 100 hours, no pink noise or white noise. Just the music I listen to the most.

is this continuous or ? and is pandora a bad source of music to burn in with?

this really sounds like a troll, but you might just be super paranoid (no offense).
 
i don't think there is any hard science that says this or that does a better job of burn in.  you can't under-do it or over do it or do it in the wrong way (besides blasting music extremely loud).  just listen at a comfortable volume, whatever music, be that pink noise white noise eminem or lady gaga, and leave it playing overnight continuous, not continous, doesn't matter.  bit rate doesn't matter.. higher quality is probably better, but that is just because it perhaps plays more of the frequencies.  just play the music you will want to be listening to.
 
i think you are overthinking it.

yeah sorry... i am super paranoid... i really don't want to screw this up at all which apparently isn't possible lol. but yeah so you're saying pandora is bad quality? i guess im gonna burn in like 100 hours with pandora first then possibly cap off with some pink noise.

From what I've gathered from this site, the only things that really need burning in physically are capacitors and amps (and someone said one certain headphone I can't recall the name).
 
My experience is that it takes maybe 100 hours for me to get a real feel on the sound of a new headphone and most likely, as others have said, this is where the burn-in phenonema arises. As your ears adjust to a new headphone (which is the majority of the sound, as it is what creates the sound from the digital signal) you get accustomed and in that interim it seems to change (this will become evident as you get more cans). It's not the can itself that changes but it's specific reproduction of sound which your ears are not accustomed to which takes some time to get a hold of.
 
I don't mean to be difficult or anti-burn-in but that is my opinion/viewpoint at this time.
 
To be helpful, I've never heard anyone state that there is a "wrong" way to burn-in headphones so I think you're safe doing it however you like. But in my opinion the more you listen to them, the sooner you'll have grasp on their specific sound signature.

Allow me to share my experience with 2 IEMs that I own and how IOM this "burn-in phenomenon" worked for me...or didn't. I had my RE0's some 2 months back and at first listen, they sounded so thin and the bass seemed so anemic. I gave it time and allowed this "burning-in" process to proceed and as the hours and days and weeks went buy, I felt that the sound improved and started to become more to my liking. But as the days went by and as I was enjoying my RE0's, then came my new FA DBA-02. At first listen, they sounded a bit weird, similar to my first impression when I first listed to my RE0's. So again, I gave it time and see if it improves. Since I only have two ears and can only listen to a pair of IEMs at a time, I decided to give my RE0 a vacation to give way to my new phones. After a few weeks of using the DBA-02, the sound seemed to improve and like my RE0s, I started to like what I was hearing. But wait...what about my RE0s. I used to like them and I only intended to place them on hold while I was toying with my new DBA-02. So I went back to listening to them, my RE0s. To my surprise, the RE0s sounded weird...again. What went wrong? I thought...I realized that they sounded like when I first listened to them when they were still new. So I started listening to them again and guess what, the sound seemed to improve in time....again. In a nutshell, I think that this "burning-in'" phenomemon is actually more of the brain that's doing the burning-in process and less of the hardware as pointed out by "permagrin". As we continue to listen to the earphones, we tend to get accustomed to the sound its producing and our brain and/or ears adjust to them. So better just listen to your phones, enjoy your music and worry less about this burn-in thing

FWIW, there is little evidence that burn in actually affects a dynamic driver. If you go look at FR measurements before and after some long burn in, there is little, if any change. These changes are so small they are more likely caused by a slightly different angle when they were tested.
 
So, as far as burn in is concerned, it as far as anyone has measured, does not exist. So, in a physical sense, your headphones undergo absolutely no change. That's right - 0 change.
 
Psychoacoustic break in is a whole other matter and how long it takes is purely personal.
 
Forget all the burn in rubbish and just enjoy your headphones. 
 
AND FOR THE LOVE OF HEADPHONES if you do not like them, don't hope burn in will fix the sound. It won't. You might end up liking them after extended use, but if you don't like them, burn in is no remedy -return them.
 
So, there is no best burn in track. Just listen to your tunes, and enjoy. End of story.
 
End of Thread.

Just use them.The changes will be so slight, it's not worth worrying about, especially coming out of an iPod which isn't the worlds best source!
I would avoid pink noise, as it is not what they will be repoducing anyway, and has no dynamic range. Simply put them in your ears, and listen to your music.

1.Just listen to your IEM for 200 hours
 
2.If you don't like what you're hearing after those 200 hours , sell them and buy another IEM
 
3.Repeat steps 1-2 until you find IEM happiness.

Man, you need (an additional) hobby. There is nothing to screw up...
 
Put the things in/on your ears and LISTEN to them.
 
If after a month or so you like them, great. If not, move on.
 
Yikes...
