I like Black Sabbath and Judas Priest. "Angry Again" reminds me of the times my bro and I would laugh our butts off with "The Last Action Hero". Good times.

Only advice I have to offer for in-ear solutions is getting the right size tri-flange tip to hold the mic in your ear canal, and you want the mic to be as flush with the opening of your ear canal as possible. You really want it to seal nicely and fit securely.

It'll never be perfect (nor will any measurement method), and results are, of course, going to be very dependent on your actual head and ears. As such, they can't always be applied broadly to everyone else, but they can give some context around how your ears and head might affect how something sounds. It won't account for anything beyond the ear canal, hearing loss, or mental processing.

Anyone is free to disagree with me, but I have yet to find a measurement method that better captures how I hear headphones than how I do it myself. I always do plenty of listening before measuring, to be clear, and don't need measurements to tell me whether I think something sounds good or bad. However, I have yet to see any set of measurements aside from my own that captures the HE-560 as being as horribly painful as I hear it or the HD600 being slightly "hot" in the 2-5KHz range. But, again, my measurements are tailored to my head and ears, so YMMV. Every other set of measurements I look at (and I do look at as many measurements as possible), compensated or not, require some mental gymnastics on my part to understand how they might translate to how I hear the headphone. Are there still going to be quirks and measurements artifacts in my setup? Oh yeah, absolutely. But I've seen that in other setups too. That's why you don't rely on them TOO much.

Should also mention that I'm guessing the WM61a has some product variance, which is hard to compensate for unless you have the mic professionally tested. The idea of seeing how it measures a known flat loudspeaker is a good start for guys like us. I have some bookshelf speakers. Dayton BR-1 and those budget Pioneer pairs from a few years back, with known measurements from other sources. I should see how they measure with my in-ear mic. I'd also make sure you run your measurement equipment minus mic in loopback mode to figure out any further compensation you'll need to apply for the hardware itself. My phantom PSU + ADC have a bit of inherent bass roll-off that I compensate for.

As I've said before, one experiment I want to try is my in-ear mic on different people. Rules out any mic variability. That way I can get a feel for how other heads and ears affect how headphones measure on this setup. Should be interesting, if not enlightening.

Good thoughts. I think actually my HE-560 measurements would correlate strongly with your personal impressions (I detect that peakiness there too though I personally don't find that tuning choice fatiguing). The HE-560 definitely has a interesting treble presentation & I can see people having issues with it.

edit: unattached as I just saw that they were already posted by marvey. thanks! in his post first set of images is the my he-1k measurements vs his ones & second image set is my he-560 (with that prominent 2-5kHz peak Hans is talking about).

edit2: appreciate the advice from OJneg & Hans about using reference speakers to help my measurements!! Was looking at various options just now. If anyone has any good inexpensive recommendations for me, please PM me!! Thank you

Huge fan of DP

I bet!!

I think anax is referring to the urbandictionary meaning of DP

There's also dvda... but I can't seem to find the movie clip of it
