@samwell7 &
@Mulder , I developed another EQ for my K702, for my new K702 with the new pads, and I think it's an improvement, so try it if you like. It's based on Crinacle's measurements, but the main difference is that I chose only one of his measurements - he measures each headphone 3 times, so that's 6 individual measurements because 2 channels (2x3=6). Yep, so I chose to use an average of his right channel measurements as they were all very closely grouped without outliers, the right channel also most significantly was the one with the smallest 2kHz peak, because I identified through my listening of my original Crinacle EQ (which was based on an average of all the measurements) that my EQ was taking out too much energy on this 2kHz peak. One of his measurements was a bit of an outlier on the 2kHz peak which was skewing the average I had been using before, which was from the left channel. This average of the right channel I'm choosing also had the highest 6-9kHz peak which was a similarity with measurements from other sources, and peaking in this area is pretty darn harsh....so I wanted to use this measurement to EQ that down. One other similarity with other measurements from other sources, the right channel average I chose was also exhibiting the largest 500Hz-1kHz dip, and through some more recent EQ testing I've found the K702 does indeed need a small boost in this area to help deliver impact (previously I had thought it a measurement anomaly). Here's the link to the Crinacle graph tool where I got the K702 measurement, I chose the right channel measurement for the reasons I mentioned:

and here's a pic of the measurement I used:

And here's my EQ based on the above measurement:

I did some listening tests on the tracks I use to tweak & compare EQ's, and used those tracks to tweak the bass. I found it interesting that the rolled off bass boost I applied delivered overall more bass impact than leaving an equivalent Low Shelf bass boost that extends further into the bass - I believe that's because the Low Shelf muddies the bass, as well as not letting the rest of the headphone shine as brightly......to me the EQ I did above is the optimum bass for this headphone when attempting to follow the contour of the Harman Curve....I don't think the K702 can benefit by boosting the bass any lower into the frequency range than that.
I'm pretty sure I'll still be sending in my K702 to Oratory, but this is an improvement whilst I'm (we're) waiting....goes to show that you shouldn't blindly use an average curve as a basis for EQ (or at least exclude the measurements that are non-representative before averaging, which is Oratory's approach, and also what I have done here)
