Are you saying speaker cables make no difference?

Then they shouldn't make the claims in the first place.

Why not?

What I'm saying is that no one has shown conclusively that they do.

Of course it's possible to make a speaker cable or interconnect with sufficiently high resistance, inductance and/or capacitance so as to alter frequency response to the point of being audible. But those aspects have never been at issue.

The issue has always been about other things. Copper versus silver. 99.9% purity versus 99.99999% purity. ETP versus OFC versus OCC. PVC versus Teflon versus whatever.

Because if you make an objective claim, you have a responsibility to substantiate it. If you're not prepared to do that, then you shouldn't make the claim in the first place.

OK.

So there's no discussion then.

End of thread because John (The op) must have been telling porkies. There's no proof that his headphones changed.

Let us all know when something new happens.

Far as I can tell, the OP wasn't talking about cables, which is what you were talking about.

But if you don't wish to discuss a subject that you brought up, that's fine with me.

I am happy joining this discussion, becasue it seems to be one of the most discussed topic on head-fi.

One month before I bought Utrasone pro 900, my first listening was dissatisfying, because I liked the bass and the mids but the highs were harsh and sometimes a little unnatural. Damn I was angry that I gave out 330€ and I do not like it. However they were lying around for two weeks.

5 days before I started to burn them in. I listened to some certain songs that I always listen and some sensitive songs for highs. Now I am waiting for results. I let them burn in for 300 hours.


-I did not listen too much to the Ultrasones, so around one hour or so, including the tracks that I have listened for the comparison later
-through this I can say that I will not have brainburn in, since I do not get used to these headphones
-I will not listen to them in between, I will wait till the 300h are over, because I think I will hear the differences better than with listemning in between

I am excited about the result.

I was talking about cables because this is the other issue that the 'knowing people' refute. (Especially on headphones rather than on speakers) However in the early 70's, people spoke the same way about speaker cables. They were wrong.

You're not discussing it. You're informing us that we're all wrong.

But since burn in doesn't occur, there is nothing further to discuss since the op must have been telling porkies, because as you say, there is no proof of burn in.

I'm sure burn in is real.. I just doubt the sound would change.. It's more of your ears getting accustomed to the headphones.. You know how many songs I didn't care for the first listen.. After hearing them over & over, I begin to like the beat & the song in general.. Ring of fire.. I want to be your dog.. Rehab.. Come to mind..

I listened along the way with mine. The only thing that happened with me was that the K701's split my CD's into good and poor quality recordings.

I kept the ones that I felt sounded strange to one side and listened to them again much later on. The sound of those seemed to have changed slightly after quite a long period.

Either burn in or I had just adjusted to the sound of the 701's. I don't know.

Maybe it's like a new pair of glasses. For the first few days, you're having trouble all over the place......

...and after all this, why hasn't anyone made responce graphs for a pair of headphones, before and after burn-in...

I wonder if the changes are fairly small and in parts of the spectrum. It would be nice if one of the hi fi mags tried this.

If burn in doesn't occur then the op must have been telling porkies in his original thread opener.

Interesting testing style. Yeah this glasses example might be true to burn in, but I hope burn will change the headphones, or I will sell them.

I do not believe into a myth, I decided to burn in, because I thought the reason might be a certain wearout. Also if you read all the posts where people say that they have found differences after burning in, they all apply to extremes. It is maybe because I am just about 140 posts in head-fi, but differences I have read are only in areas of highs or lows.

Hope the best, expect the worst.
