I'm telling you, the effect is there no matter what. Go to a music masteriing forum and ask those guys about it. They'll have an explanation. No doubt, some headphones will pick it up better than others though. Guarantee it has nothing to do with headphones speed. Look at the post where he mentioned how intense it was on k81's. We all know those arent known for their speedy response.

No I do not think it is the extra bass. On the 650s I can clearly hear the details better where on the MS-2i I can hear the sound but it lack the detail to determine what the sound is.

I have always though the 650s were more detailed than my MS-2i. But this might not be detail at all. The Senns could be slower.

It is concerning that I can not hear it on my speakers. Either it is a problem common to headphones or my current speaker set-up does not have the detail to hear the sine change?

export the kick and sinewave separately for me, I want to play!

It is, the thing that happens with the sinewave is exactly the same through all my headphones.

If you don't think it's psychological try to focus ONLY on the sinewave, if you can focus really well you hear that the sine wave is exactly the same through the whole sample, with no changes in freq.

What I meant by speed was that they *aren't* fast enough. That makes sense that the K81 distorts more since it would be slower and therefore wouldn't be able to keep up with both signals at once. Ofcourse this is just my theory so far, I would love if someone could explain the reason why it happens.

Certainly, I very much doubt your speakers lack details

If it's worse on the K81 this is pretty much ruled out, as I'm sure your B&Ws have more detail than them.

Here they are, rendered individually straight from the track without modification:
Kick (~5Mb)
Sine (~5Mb)

It seems like it's IMD but does anyone know what actually causes it? Not enough transient speed? Diaphragm rigidity?

b0dhi do you play cs?!

Oh

is that the sine wave? But how can I concentrate to the point that I don't hear it?? I guess my concentration makes me hear what I was expecting, even if it was wrong! God damn this "placebo" is strong.

lol What. I play fear combat

Where is this coming from?

A closer view to see the waveform:

 

[qazwsx]

Well I took the test and it must be inaccurate because my UR20 was the fastest of all headphones and in reality it takes two months to respond to anything.

oh there's a really awesome css player who calls himself bodhi, he's a real professional with a salary and everything

umm yah, it's the sine and the kicks...

If you filter the kicks in an audio editor the sinewave remains constant.

...heres the verdict VIA spectral analysis..

As you can see here the sine is not effected.

[plywood99]

Isn't this just distortion? More noticeable on single drivers, aka headphones, and less noticeable on two-way setups. Three ways should totally nullify the effect, since the crossovers are separating the signal...

EsthetiX, what cans did you test this out on? Maybe I'm just a dunce with subtle Hz shifts, but I'm not noticing the effect on my Equation RP-21. since you've got a pair, it makes me wonder what your take is.

 

[EsthetiX]

i hear it on every headphone I have... even my KRK monitors. It's subtle but its there.
