Great idea. Non-trivial assignment.
Experiments would need:
1. a stable measurement jig (possibly a head/pinna, but at least something head-sized for proper seal)
2. good resolution measurement equipment, calibrated mic, etc.
3. equipment to measure and log environmental parameters (temperature, humidity, barometric pressure)
4. method to verify stability of the above measurement equipment
5. two samples of each model to be tested, one as a DUT, the other as a control. That gets you two samples of each, left and right
6. A carefully designed test regimen, measurement intervals, burn-in signal type and level, verification of level (SPL at the ear)
You need to do at least this. If you do less, there's not enough to avoid the arguments.
Why not, instead of arguing, create and run some experiments? I've been trying to arrange to actually do this with some headphones at least.
