This is a headphone for listening to music, not for audio mixing. I wish you success with your review site idea, but it would not be one I would personally seek out (saying this as an audio nut myself). There are a few websites that measure more than just the sound signature though - e.g. https://www.rtings.com/headphones/reviews/sony/wh-1000xm4-wireless#page-test-results https://www.rtings.com/headphones/reviews/sony/wh-1000xm4-wi... As an aside, applying scientific principles doesn't automatically make the review any better. Science works by proposing a hypothesis/model and collecting data to see if the data matches the model. If your hypothesis/model is just average, and not world-class, then the most carefully collected data doesn't hold much weight/value. For e.g. Minor changes in the sound signature/frequency response are only audible when you listen to the same music across multiple headphones, and that too when you're carefully listening. Also the sound signature can vary when the fit of the headphone changes as per the individual head shape/ear shape/etc. All this is assuming there is enough manufacturing tolerance to produce headphones with identical sound signatures, etc, etc. Ultimately you'll have to come up with a hypothesis/model that is better than the current one. Which is not to say it can't be done, but its a tall order, but I hope you give it a shot at-least. If nothing else you'll have a cool blog post :)
