Anyway, here's the result of data I collected before posting:
..........................Freq.......Imped..Max Power...Sensitivity...Driver
AKG K240.............15-25kHz...55......200 nW.......91dB/mW....40 mm
AudioTech D40fs...20-28kHz...66....1600 mW.....102dB/mW...40 mm
Sony MDR7509HD....5-80kHz...24....3000 mW.....107dB/mW...50 mm



tINY: hat's what i was going to do, but thought it best to see what the consensus from my other techies would be. I'll test both in series and parallel and see which sounds better
I'll probably stick em inside the TRS connector if I don't get a "Don't do that because.." response


That's a big difference. I bet the sensitivity is voltage sensitivity too...

You may need to get a jumbo connector if you add resistors in series - with a 20 ohm series resistor, you'll probably want to use the 1 watt size. You could add 50-100uF caps in series for a HPF, but that would be best done at the cans where you have more room.
