100+ Head-Fier
[size=small]You are only given one chance for a first impression.[/size]
[size=small]On the other hand; a first impression with new cans is somewhat controversial because of the burn-in that seemed to be required.[/size]
[size=small]That’s why I decided to let the first sound that reached the drivers of my new W1000’s to be pink noise and record it. That way, I could compare it later on with the sound sig of fully burnt-in cans.[/size]
[size=small]This is my way of working:[/size]
[size=small]I put home made binaural mikes in my ears.Here's a pic.[/size]
[size=small]http://www.tollenique.nl/Head-fi/inEarMike.jpg[/size]
[size=small]I place the cans under test on my head in the normal way, play some pink noise over them on a moderate level to exclude distortion and record to minidisk (Hi-md).[/size]
[size=small]After that I also recorded some music. I made notes of the levels so I can repeat the procedure after burn-in.[/size]
[size=small]I'll inform you of the outcome after a lot of musical hours.[/size]
[size=small]The measurements and sound sig you get are not accurate and don't lead to absolute values because of the quality of the mikes (not calibrated), but of course you can compare different cans. Which led to the next experiment.[/size]

[size=small]Pink noise on W1000's[/size]
[size=small][size=small][size=small][size=small]http://www.tollenique.nl/Head-fi/pinkW1000 1.mp3[/size][/size][/size][/size]
[size=small]Mind the levels! Notice the very different sound sig.[/size]
[size=small]Since this is not a pleasure to listen to, I also recorded a Paquito d’Rivera track with DT880’s and W1000’s. If you are familiar with either of these cans, you can somewhat predict what the other would sound like to you. You should however keep in mind that in case you for instance listen to the DT880 track on DT880 cans, you’ll hear those cans twice… Irregularities in the frequency range are doubled.[/size]
[size=small]BTW: these are fairly large files[/size]

[size=small]It works very well for me, but of course this is very personal, because it's recorded with the mikes in my ears. I am very curious if it works for any of you though.[/size]
[size=small]This method could also possibly give answers to several questions that came about these last few years on Head-fi.[/size]
[size=small]- Do some cans have real bass, or is it artificially introduced (a bump in mid-bass for example)[/size]
[size=small]- Burn-in; does it really exist?[/size]
[size=small]- Is there a way to compare cans more easily and leave out a bit of the human preference of others?[/size]
[size=small]- Can you avoid the bad audio memory when trying to compare cans on different occasions? [/size]
[size=small]I've already found some very interesting differences between cans.But that's another subject.[/size]
[size=small]For some of the answers you’ll need calibrated mikes and a fixed procedure for levels, placement of cans etc.[/size]
[size=small]Enough to keep me busy for a while. But first I’m going to enjoy my new cans. Because burnt-in or not, they already sound fantastic.[/size]
[size=small]Completely off subject but still interesting: DT880’s sounded better to me with the mikes in my ears (subdued highs).[/size]
