    That's a good point despite my questioning of using full-sized headphones on portable gear. I hope @zach915m or someone will give us a full big-boi headphone with a 600 ohm coil.

    @HotRatSalad I've heard that the modern 600 ohm DT990 is not bad, but I would imagine the vintage ones made in the 1990s would blow them away. I'm pretty sure the pair I have is 250 ohm, but is made in that timeframe and it is pretty fantastic.

    Headphone sensitivity generally sits between 90 and 100 dB/mW, IEMs much higher at 100 to 120 dB/mW. How you develop a mW of power is different for 32R transducers than 300R. Low voltage but higher current is necessary for smart devices with 3.3V to 5V, so 32R works better. 300R will need higher voltage but lower current, rather a good fit with OTL tube amplifiers.

    Right, I forgot about that. Finding electric power, Ohm's Law, etc. Still, I really like what I'm hearing with these old 600 ohm Senns.

    Do all of the same rules apply to high-ish impedance planars like the 200 ohm LCD-4?

    I have an AKG K 240 DF old school 600 ohm pair you can have for shipping costs if that's your thing. I tried to like them, didn't work.
