I found these headphones online, and I don't understand how you would be able to run 1500 ohm headphones. I wanted to find some headphones that looked kind of like these but I want to see of someone can mod the with new drivers. I came across these and was stunned because I had not seen over 600 ohms.

depends entirely on their sensitivity... possibly very easily.

I converted a kilo-ohm military aviation/tank headset and it got more than enough power from my TA-30. You can drive them with any amp that provides enough power.

And how do they sound?

All mids. Great for radioing your comrades, awful for everything else.

I was able to EQ them and they sound half decent, but still don't have all that much technical ability.

With a load impedance that high you'll mostly be concerned about providing sufficient voltage. Current draw (and hence power) won't be high due to the high load impedance.

Assuming the same efficiency, the difference in sensitivity of a 1500 ohm headphone and a 600 ohm one is 4 dB, which is probably less than you think. Or almost 8 dB from a 250 ohm one.

Electrostatic headphones have impedances to the tune of 100,000 ohms. 1500 ohm is not that big a deal as long as long as they are either fairly sensitive (which is probably the case for crystal radio headphones), or you got a high voltage amplifier (do not need much current at this point).

Hotwire it right into the back of a serious speaker amp
