Another question to those who know... These headphones have a rated impedance of 62 ohm, but they seem to be a lot harder to drive than other headphones at the same rating. Why is this? I was a bit disappointed when I realized my motherboard with "dual headphone amps rated for 600 ohms" couldn't drive these.

TapakidneyI'm just answering based on the physics, since my headphones haven't arrived yet, but the impedance alone doesn't tell you how "easy to drive" a pair of headphones is. A high impedance headphone doesn't need much current, but needs a lot of voltage to play at high volume levels. A low impedance headphone doesn't need much voltage, but a lot more current to play at high volume levels. 62 ohms is a middle of the road level that will give a reasonable balance of voltage and current requirements, but it's still dependent on efficiency, and I would assume these headphones are below average efficiency if you're having trouble driving them. I've got some fostex T50RP that have the same issue. A reasonably easy impedance, but the volume control is usually near max to get a reasonable volume on most devices.

TapakidneyWell, the K712 get loud enough it of my maximus ix hero, but I usually run them with my dragonfly red, which is capable of running them fine. Usually using windows volume between 6 and 20, when it maxes out at 100 these are like speakers.

TapakidneyThe sensitivity is 105dB/V which works out to 102dB for 8mW while most IEMs and high impedance headphones are 102dB for 1 or 1.5mW. So, it definitely requires more power. But, most of the time, the amount of power required for average listening levels are less than 1mW. Any MB should be able to deliver it.
