I know the Hifiman HE-6 stands out as truly power hungry, as does the AKG K-1000, but are there headphones that go even beyond those? Headphones that have even lower sensitivity or ridiculously high impedance? I'm just asking out of pure curiosity :)

I see. So there are special types of high voltage amplifiers meant for these headsets?

I can't find what makes these so difficult to drive though. Do they have a very high impedance or are they just very inefficient?

Electrostats? What type of headphones are those?

Lower impedance's isn't a problem, my amp can deliver close to 8W into 50Ohms. I'm glad to hear that there aren't many high impedance headphones that require the same kind of power :)

Hi. I'm constructing a headphone amplifier that's supposed to drive any pair of headphones, but I'm not sure of how powerful I actually need it to be. I'm currently getting about at least 1W output up to about 150Ohms which is enough to blow most headphone, but what about headphone with a higher...

Hi. I'm making a headphone amplifier with a 4-pin XLR output as well as a 6.35mm jack, but I don't know the pin-out of this connector, could someone help me out?

Thank you, I will give it a read :)

Do you have a link? Googling gave me some responds, but which blog were you pointing at?

We are currently working on a project where the idea is to start a virtual business that manufacture and sell headphone amplifiers. Please respond to this quick survey if you have the time. The idea is to get a general idea of what needs we are actually trying to meet.  ...
