I wonder how the HD558/598 would measure if you removed the material "underneath" the grill, so that it would be completely open like the HD600. I did that to my HD598 and liked it at the time. You can find pics on HF if you're not sure what I mean. I also had them recabled (nicer, thicker cable, dual-entry), though I'm not sure if that made any difference really.

Still really interesting seeing how they compared to the HD558!

Nice Data.
Looking at the FR-Graph, I believe to know this is a newer one with the "silver Screen" isn't it :P ?

I think so... FR is not smoothed (below is the FR 1/6 dB/octave smoothed).



BTW the apparent driver imbalance and weirdness in the left channel treble might be a measurement artifact (below is a second earlier FR 1/6 dB/octave smoothed FR plot which does not have the driver imbalance and treble discrepancy) ... Might have to remeasure tonite to double check...

CT's HD600 are actually recabled... Maybe I'll make a cable comparo there popcorn

BTW, I also made a comparison of the HD558 FR w and w/o the material under the grill HERE...

The HD558 measurements in this thread are with the material under the grill (stock HD558).

Were you using different smoothing, or is it just because the scales are spread out more on the old 558 FR's?

Yeah, well, you know, that's just, like, your opinion, man.

It's the scales Ship (-30 dB to 0 dB vs -35 dB to 0 dB). The HD600 is smoother. Also there might be a measurement error on the L channel. I'll re-check tonite.

Should be both the stock and Zu Mobius cables down there...cool to get different measurements and graphs on this pair.
 
BTW, thanks Shipsupt for selling me these!

Alright. Here we go again...

Frequency Response:


Differences from previous results: 1/6 dB/octave, 35 dB range on y-axis, resized window (to match HD558 results), re-calibrated to 90 dB, properly position left cup in fixture.

EDIT: Corrected Distortion scales (10 to 100 dB range)

HD600 vs HD558 take 2 ...

Right cup (yellow is HD558)



Left cup (yellow is HD558)



Note differences in distortion (Right cups)

HD600 (EDIT: corrected scales relative to HD558 plot below)



HD558



NOTE: Stretching plots can give a false sense of smoothness. It is best to overlay FR. The HD600 does indeed sound very similar to the HD558 to my ears. However, to me, the HD600 sounds a little smoother, cleaner and offer better detail.

A Sansa Zip "can drive" the HD600, but one definitively needs to crank it up almost to max with high dynamic range music (like -4 dB form max or more depending).

EDIT: ... and the Valhalla kicks ass with the HD600...

When you say "w/o the material under the grill," do you just mean the foam you can remove or everything (foam, plastic, thin fabric, etc.), so that inside the cup is 100% transparent minus the metal part of the grill. I ask because the post you link confused me...

Sorry about that Hans, for the HD558 I just removed the foam inside the grill. Removing the foam (only) had the effect of reducing the high mids a little relative to the rest of the FR (I find the last two plots on that HD558 link more revealing about this).

The distortion measurements between the HD558 and HD600 really do sum up the differences between the two. The HD600 simply sounds more "hi-fi" - clearer, less blurry, better articulation, etc.  Still, the HD558 is a great starter headphone that's easy to find for dirt cheap.
