Looks more like Tyll's now.

I don't know how your rig is set up so it might not be physically possible but setting up something head sized on the opposite side of the coupler so the headband can provide the right amount of force would simplify the process.

Also HD650 pad effect:

Yeah, that's why I do. There is something opposite to simulate the size of a head for clamping. Generally sealed headphones are really tough to measure in the bass because the pressure is so dependent upon the seal. Same goes for most planars, because when you think about it, they are really closed headphones in a way.


LOL, you should see how Grados measure with new pads and disintegrating pads.

Hmm...  Must be harder than I though if you've still got to go though all that to get a good measurement.  I was thinking that maybe you didn't because I can get some headphones I have around here to measure like they sound just laying them down over my creatology covered aluminum plate with a hole in it but other need the right amount of pressure on the pads.

Have you seen Tyll's video where he shows how he measures the FR on his rig?  He plays the 30hz square wave on headphone and watches the HATS' output on a 'scope and uses the square wave's shape to judge a proper fit on the HATS.  That might help but IDK if you can do that with the software you have though.

Not really. The Sony is the odd one for several reasons. It's a closed headphone. It's pads neither rest over the ears or on top of the ears. It's sort of in between.

I've got several couplers. One lined with foam, another with foam/felt, another which is just foam, another free-air mounting apparatus, etc. The very open headphones are easy. Planars, Supra-aural sealed, sealed etc. require use of different combinations of couplers with various averaging and compensation techniques, etc.

Interesting system you've got there...

I guess you're gonna actually have to go back to listening to all of them then huh?

Yeah. Admittedly I was lazy with the MDR-V6. That one really threw me in for a curveball because I didn't have a method or "profile" for it.

So you've got the "closed, half-assed 'circumaural' with bouncy pads" coupler down pat now?

Oddly enough I think that's actually a serious question too...

At least I have one measurement profile or model for it now, which I didn't before. If you've ever wondered why I've hesitated from posting FR graphs until fairly recently... now you know why.

Could you please post the compensated 1350 graph?
