How many of you actullay believe IE8 burn in effect? - Page 7

Go back and read my entire post, you are only reinforcing my point.

Summation of this thread:

"I believe in burn in because I've experienced it."

'Oh yeah, well science says you are wrong, gg noob.'

yawn.

i have to agree with seedhouse. although i seem to notice differences in headphones after "burn-in", this is not an objective test for anything. saying things are "widely accepted facts" is not a solid argument without proof that these facts are substantiated. hearsay is not really proof of anything either.

they do require burn in. i let mine burn in for about a week straight. i kept doing periodic comparissons between my IE8 and SE530s. After that first week or so of burn in i don't even listen to the SE530s anymore. except when i go to the gym then its strictly shures. but i love the IE8 after burn in. before burn in they were good like out the box but afterwards they are GREAT!

@Ed seedhouse:
Golly! Sir, if you want talk empirical evidence, please post the procedure and result of a
scientific experiment similar to one containing 10 dynamics IEM/headphone, 1 500 hr burned-in another,
completely unused and the rest randomly burned. Providing the identified burn-ed/not burn-ed
IEM/headphone as a reference, the administers telling them to listen to the other 8 IEM/headphone
and identify which ones are burned-in which is not. If the test want to be more authoritative
it can have two groups of participants: one consist entirely of head-fiers, the other do
not. The discrepancies in the result of these 2 groups can then be analyzed to see if
people who "heard" burn-in can actually recognize such occurrence in a different
environment. Remember, the experiment is to show whether people can identify
differences without been influenced by "mental burn-in" or the placebo effect, it's
not trying to measure change and then decide whether the differences actually
mean a damn thing.

As for human beings are fallible and we adapt to transducers and etc., no doubt
we do, but can you provide any explanation with empirical evidence that people
can listen to one transducer, change to another transducer, and upon hearing
the first one again just to find out they sound much better?

Please, blanketing this issue with "previous measurements prove that no change
occurred with burn-in" to me is bulls***, I can care less if the measurements disagree
with what I hear. However, if a test such as one noted above is conducted and the result
shows people cannot consistently recognize new and burned-in transducers, now
THAT can make me reconsider my beliefs and I think many others will do the
same.

Could've ended right there.

Honestly, it's about as futile as religion vs. science.

definetly the ie8 needs burn in,they sound like crap out of the box and then began to sound like $400 earphones after 100 hours of pink noise and music.burn in is not a myth,it is an evident and it happens,i dont know how the hell it happened BUT IT IS DAMN TRUE AT LEAST WITH THE IE8.PERIOD.

Bah, I don't believe burn-in of the physical IEM components. I'm right there with you Mr. Seedhouse.

My mind "burns-in." I adjust to the sound in the same way that I have adjusted to the accents of two individuals that I work with. I could barely understand a word they were saying until I worked with them long enough. Obviously they have not changed their accent, but it took a while before I could make out their words.

IEM fit and seal "burns-in", too. It always takes a number of tries before getting the right fit and seal with new IEMs. Sometimes you push them in too far, not enough, or at an odd angle. Eventually they settle and you are able to whip them in and out of your ears. For me, this affects the sound more than my mind burning in.

And finally, there are times that I listen to music and it sounds crappy, then I listen another day and it's great. Mood has a lot to do with it. Not to mention that small changes in volume will skew perception as well. To those making comparisons with differing volume levels, your tests are greatly flawed. The mind is easily tricked, that's for sure.

From the booklet which came with my Dynaudios some years ago:

"It is important to know that your new DYNAUDIO speakers contain newly manufactured moving parts which do not perform up to intended DYNAUDIO standard, until they are properly run in.
A brand new speaker needs a certain break-in time period in order to sound as harmonic, beautiful and play as safely as one can expect from DYNAUDIO products.
Everytime you start listening to your DYNAUDIO speakers, give them about 3-4 minutes warm up time in order to fully reach their breath taking musical capabilities and performance level."

Not earphones I know, but thought I'd throw it into the mix...

I know the IE8s improve significantly after a few hours burning in from new, as have my FX500s. But 200, 300, 400 hours....? Hmmm, I very much doubt it. The view stated above by fzaba, apart from his initial outburst, is closer to reality methinks.

Thank You. Argument over.

yawn

Well I agree with the yawn, because repeating an unsupported claim a thousand times doesn't make it any less specious. And "I believe in burn in because I experienced it" is just an unsupported claim, for which there is no evidence.

And who wrote that stuff? Their engineering department or their advertising department?

Notice that the burn in time quoted is three or four minutes, not hundreds of hours as is being claimed by various folks here. They are saying that there loudspeakers will "fully reach their breath taking musical capabilities and performance level" after three to four minutes, which is directly contradictory to people's claims about the IE8.

Sennheiser's staff, who actually designed and manufacture the things, refuse to make any such claim about the IE8, though they are not bold enough to contradict those who do, sadly.

Now a loudspeaker manufacturer is in a conflict of interest on this because if he can convince you of "burn in" you will listen to his system longer and be less likely to return it for a refund. To their credit most manufacturers largely resist this temptation.

Since the article quoted directly contradicts the claim of extended burn in over many hours, I suppose then you will give up this belief? But I don't think I will hold my breath waiting...

All this is true, in my opinion, but I don't think "burn in" is a proper word to use for these well known phenomina.
