Does everyone here believe in burn in? - Page 3

there is the burn-in....then the burning....finally the burn-out...my charcoal.

warm up warm down...sports, worn in worn out..my tyres.

err...break in break out..felons.

allthings headfi....freakin freakout

NO!!

Have you ever seen a post that after 300 Hrs my head phones sound like crap?  No it's always " They are so much better now after"

If Burn in was a real deal " Not in your head"  There would be neg reports as well.

Every action has an equal reaction!!!

I was a non believer, but experienced it for myself with my Ultrasone Pro900. Straight out of the box , they were awful - boomy bass and piercing glass shattering highs. It was so bad to my ears that I was going to return them right away.

But I thought, what the hell, I'll give Burn-in a go first.

I plugged them into my amp and let them play random music from my PC for about a week. In that time I continued to use my IEMs. When I tried the 900s again, it was instantly obvious that the trebles had smoothed out and were no longer painful and the bass had tightened up.

This could not be my ears adjusting to the sound because I hadn't listened to them again since that first session.

Burn-in makes sense to me now - there are moving parts which flex and vibrate and I think they need to loosen up just like most new mechanical products. However, I think the changes are quite subtle and vary depending on the headphone.

Or it could be expectation bias.... just saying.

well when they test and tune the driver im guessing they go with a burnt in driver, not a brand new one as it takes time to tune them, so when they manufacture them, they are not yet in optimum state as they want, they will sound as they were tuned once burnt in, so that is why there are not many negative reports. just my opinion, and some companies pre burn in headphones at the factory. just saying.

And yes burn-in makes sense as the drivers move, thats why dynamic drivers are Usually more affected than BA drivers.

If that was true why did you burn it in? I have a hard time believe your claim.

This will be my last post in this thread for now. Don't want to start a flame war.

My brand new Sennheiser HD650 and HD800 sounded grainy in the first few hours.  

Here's my take on burn-in:

I feel that there's 3 main situations with burn in that are dictated by how much a person initially like a headphone (this is still saying yes to burn in though):

• If  person doesn't like a headphone and burn in doesn't improve the sound, it will be considered a bad headphone and probably returned- addressing people that say why does burn in always improve sound
• If a person dislikes a headphone but bun in does improve sound then they'll truly appreciate the burn in and the headphone
• If a person likes a headphone to begin with they will probably be less critical of the sound changing and may not notice at all (hence all the people saying a headphone sounds good right out of the box)

My theory kind of goes against both people that say burn in is true and those saying it doesn't exist so... well... wanted to share it anyways 

Don't hunt me down and kill me its just my opinion... feel free to disagree with it.

I feel free.....

no one's forcing you to care lol... be free and spread your wings :P there may be a day when everyone agrees with each other... but it is not this day. (or probably never for that matter but that wouldn't fit the lord of the rings reference as well...)

FWIW I have experienced so called "Burn In" both with the 990's and 701's .

- Though, I remain open to the possibility that perhaps we change by accommodation  rather than the hardware changing,

in my case to these two cans High Frequencies !
