Headphones. Is it an impedance thing? Why do they have different SPL?

I run into different headphones and different field mixers. Why do different headphones have more or less SPL than others? Is it an impedance mismatch thing? If so, what questions should I ask or research to find the best match of mixer output and headphones?

Impedance has a lot to do with it, so does sensitivity.

Rane used to publish a list of headphones with specs. They still may.

I remember the AKG 240 being the least sensitive and the Sony MDR 7506 best the most sensitive.

Funny you should mention the AKG and the Sony. I have both and the Sony was a lot hotter than the AKG that I also had with me. I guess that I had both ends of the spectrum and I didn't even know it.
