I have. Pretty much no difference. Is anything maybe a little but its so minute that I could care less. If you don't like the sound before even after burn-in you won't like it. These drivers dont change from one to another after a "burn-in." Only thing that would happen is to vibrate looser to allow to lower bass to come in.

 

What you experience is most likely a head-in. All psychological but still good nonetheless.

BTW even Sennheiser recommends 48 hours pink noise for HD800, think they are a scientific bunch. There used to be a sticky on this topic (burn in), wonder where is it gone to.....

Headroom recommend giving the K701 at least 300 hours...this is probably the only headphoneson their site that they recommend burning in,so it must say something about these cans.

I would have been nice if they could have made two frequency response graphs for the AKG 701/2. One graph for a fresh out of the box AKG 701/2 and another graph for the AKG 701/2 with about 300 hours on it.

In the thread of the new measurements lab of Tyll he ran a first test regarding burn in of the K701, and the result was that the differences of the frequency response due to the difference in  placement of headphones was greater than what the effect of the burn in was, so in frequency response it might seem that the difference is not that significant. But this is just a first test, and my real point is that Tyll will probably due more testing about that in the fall, so we will see if we can see any change in frequency responce (or THD or some other thing) around then.

A person isn't a troll just because he disagrees with you.

 

The analogies make sense and a similar logic can be offered for headphones.

Given its never been proven one way or the other, and never will, and relies solely on anecdotal evidence to further the belief, then that opening statement can't be backed up.

 

Just because other things wears in, such as shoes, which breathe and mould to your feet, and cars, which are far more complex, does validate the case for burn in.

 

Common sense doesn't tell you something will get better with use - stuff wears out. The less demands made on things, the longer they can last.

I called troll because his opening statements were that burn is real, and then gave specifics of its effects. No one can make such a claim. I disagreed with the analogies too. Shoes are not mechanical, and cars are far more complex. It's like comparing apples and Mac's.

Here's some data suggesting burn-in happens

And enough of you guys' analogies, they are painful to my eyes. To quote Orwell, "staleness of imagery" and "lack of precision"

i compared shoes and cars in general not directly, thats the how it works. 9 out of 10 people believe in burn in whether its real or just a psychological effect. just my opinion. if you dont believe then its up to you. theres no problem with that but you just sound like you know everything about audio

Maybe he doesn't, but I know he knows and frequently visits someone personally who just about does :P

Where did you get this information?

post #42 of 42

From Sennheiser rep. (& tec. support UK), John Willett, postings on head-fi on Sennheiser HD800. He posted the same information on a few threads.

 

Here is one from 'Break-in for HD800's?' thread:

 

http://www.head-fi.org/forum/thread/433809/break-in-for-hd800-s

 

"The designer suggested 48-hours with pink noise.

Reading these forums - the consensus appears to be between 100 and 150 hours.
"

 

 

Here is a link to another posting from John Willett on another forum re: burn in of HD800 (see last posting on the page):

 

http://www.gearslutz.com/board/remote-possibilities-acoustic-music-location-recording/1143-best-headphones-monitoring-4.html

 

"Just remember they need burning in - the designer recommended 48 hours on pink noise and many users seem to find 150 hours on average with music.

They do also need a good amplifier - I use the Grace m902B with mine, but I have heard the Lehmann Black Cube and DACS Headmaster also recommended
