German company not shipping to Europe, what a joke. I was tempted to spend money I don't have on more headphones I don't need, now I'll have to responsibly save it, thanks Massdrop :(

Eli35where do you live? in the netherlands you can get the same headphones here: https://www.bax-shop.nl/producten.html?keyword=beyerdynamic+dt-770pro

Eli35Sure, keep in mind I am no audiophile so I cannot give a detailed description. What I can say is that so far I love them although I am working off of my mobo directly while I await an Amp/dac. That being said, they are REALLY comfortable, light the sound is clear and clean. The 80 ohm definitely needs an Amp for me though because my M50x's are way louder than these but of course they are something like 36 ohms so its a poor comparison. I may eventually buy some leather pads to see how it changes the sound. I absolutely recommend them.

KioshiThe main reason why your mobo can't drive the DT770 80 ohm as loud as the M50x it's not the increased impedance, but the sensitivity difference (99 dB/mW for the M50x, 96 dB/mW for the DT770). Also note that impedance does not affect at the volume by itself, only the sensitivity (i.e. the "efficiency" in terms of output volume to power supplied).
People think higher impedance heaphones need more power to sound as loud as lower impedance ones, but that's completely wrong, they just need more voltage but less current. The thing is that most solid state amps (the ones you can find on embedded IC in every PC/smartphone/tablet/whatever) are good providing current but struggle to output high voltages; that's why the higher the impedance load, the lower the power they output. But the only spec that determines the power needed by some headphones to output sound to a given volume is the sensitivity.
You can check exactly how much power (voltage and current) does any headphones need here: http://www.digizoid.com/headphones-power.html. BTW, most companies list the sensitivity as dB/mW (which is absolute) while some others use dB/mV (which is relative to the headphones' impedance). If not said otherwhise, consider the sensitivity is listed as dB/mW.
