dt770 pro response graph?

[Destroyer159753]

Any more insight? I appreciate all of your help.

Have you thought about equalizing them by ear? Any particular reason why whatever sounds best is not?

And why don't you understand BowerR64's graph?
It is pretty similar to the dt990's

This is the program i used. I have everythign set to default. Anyone can do it really. You could use a computer microphone and enclose the computer microphone with the headphones. You can set the program to sum both sides into 1 freq line.

I've tried equalizing them by ear based on what sounds neutral and the general shape of the graphs, but these are basically the only professional headphones I've ever listened to, so I don't have much experience lol.

BowerR64's graph makes somewhat sense but the scale doesn't make sense to me. It looks like 140 hz and below its perfectly flat and above 6300hz I don't know what frequencies they are, what are frequencies below 100hz and above 6300hz?

Thanks.

Dang, I can't find my DT770 measurements.

They do have a terrible 3 band response. As I recall, the bass was lifted about 8 db above mean all the way up to 150 hz, with a deep notch around 150. The rest was pretty jagged, so I sort of gave up (I didn't need another challenge). I really believe that those cans were voiced to be audible above a noisy environment, so neutral response was not a priority.

Bring them over and I will level them out for you

Lol, well I mostly listen to trance and rock so they sound quite good for that, equalizing them is quite the puzzle. When I contacted headroom about 2 months ago and they said that they were updating their databases, they said they were migrating graphs and making new results, supposidly some of the graphs were not updated recently and had to remeasure some headphones, lol maybe I should try e-mailing them again and just directly asking for any graphs they have on the 770's.

Oh; you are looking at the Hz/10 as everything is on a scale of ten. If you look at is as just the number it says, with the last 10 being 1000, it makes much more sense. The main problem with the graph is it doesn not go in to the high frequencies.

With a little guesswork I implimented BowerR64's graph fairly nicely, of the 3 graphs I've tried I believe it sounds overall the smoothest. I think this will satisfy me for a while lol. Thanks.

Well for one im not using an amp to power these cans, these are the highest that i have being 80ohms. My radio can bairly push em. So the problem is the level is to low to read the lower end. Sorry about that, i guess i could use an amp but this would color the sound a little. The only amp i have is a cmoy.

This program measures from 10hz to 20khz, it dont show 20khz thats the end of the top. I think it reads the same as the headroom type. This isnt the quality though. Im not saying its right it was just somthing to tinker around with, to learn how it works and i wanted to test some of my cans. The microphones im using are just ratshack micro element type.

If you look at the bottom it says HZ/10 you multiply the freq shown X 10

 

[BowerR64]

Here you can see where the 20khz line stops. I tested them threw the cmoy with a little more volume. You can see the amplitude on the graph is a little higher.

A great improvement from the old graph, thanks. When equalizing I made the baseline -50 on the new graph, my equalizer settings turned out to be fairly similar to the old one except for a much higher raise at 125, and general raises from 1k to 4k, but this crazy quick jump from 6300 to 20000 makes it very hard to try to tweak anything above 6300hz and my equalizer only has a 8khz and 16khz after the 4khz bar so I don't even know what to do with them lol. So far this new graph has made a huge improvement in overall sound, so close to perfection

[BowerR64]

I dont understand what your doing, your using these graphs to tweak your EQ settings?

 

[Destroyer159753]

Yes, to equalize my headphones.

 

[Destroyer159753]

Anymore advice from anyone?

These graphs don't look to accurate. In the one that tests unamped vs amped (cmoy 3/4), the x-axis isn't labelled the same, and it doesn't make much sense to me.
