Yes, my comments on IE8 burn in can be found here

Here are some of my burn in points, from memory:
- 20 hours of burn in the soundstage opened up and the bass extended
- 70 hours the treble started to come out
- 100 hours the mid-bass hump was greatly reduced
- 150-170 hours they surpassed the Phonak PFE (w/black filters) in detail. Mid-bass was down even more from 100 hours, and the treble was opening up. The soundstage seemed to widen quite a bit more.
- 200 hours the treble kept opening up and the mid-bass hump was down even more leaving a warm presentation
- 250 hours the treble is fully opened up, audible to 17KHz (my hearing might be limiting that) see here for more detail.
- 250+ hours, really enjoying them

Burn in time depends upon personal taste and what other headphones you listen/compare to. Some people like it out of the box, some don't. I didn't, but now I am loving it!

I believe it takes somewhere between 200 and 250 hours to fully burn in, YMMV.

@average_joe: What reference did you compare the changes to? Did you have a pair of fresh IE8 on hand for A-B test all through the burn in period for comparison?
And all through 250 hours, have you always used the same equipment (source, amp, cabling) and accessories (tips, bass settings, etc)?
Thanks!

i think with 250 hours of burn in...its your ears that are burned in..not the headphone.

I liked the IE8 immediately, and didn't think they sounded crap at all out of the box. But I liked them a whole lot more after 10 hours or so, not because I noticed any major changes - but because I adjusted to the sound signature pretty fast. When I had my TF10, I remember thinking they sounded plain weird out of the box (and balanced armatures don't need any burn-in), but it did take me a few hours to adjust to the different sound, by which time I loved them. So my 'ears' adjusted, but the sound didn't change. With the IE8, I like them more all the time - but I'm not convinced it has anything to do with burn-in. I think it's just because they sound amazing!

Im noticing slight changes constantly its so hard telling what is burn in and what is just me becoming more in 'tune' with the sound signature of them but either way im absolutely loving it, never had phones i enjoyed so much

I agree with soozieq for the most part. I thought they sounded good..not great out of the box. As the days went by and I burned them in while not using them, I think the sound improved a thousand %.. but I am not sure if it was me getting better seal/tips or if it was just burn-in. It was probably a combination of both. Either way I am loving them. Just wish the stalk was a tad longer to go further in ear...that is my only complaint. Small price to pay though for the sound the produce.
