Just got these and been listening for a couple of hours. Dell PC foobar/jplay->Audioengine D3->Kora Crescendo-> T50RPs. They don't come with the stupid 8.5mm to 3.5mm adapter. So, I have no choice but to use the headphone out on my preamp. I ordered a V-Moda cable.
The sample I have has some problems. Right channel sometimes lose signal. Disconnecting and reconnecting the cable from the left ear cup helps a bit but sometimes still cuts out intermittently. So, this guy has to go back eventually.
I'd imagine these are boring to some especially if they ar using this headphone for gaming. But, I like the mids. I wonder whether the mods spoken about will add to or subtract from the liquidy mids. Definitely need to control the splashy highs. Or, maybe these will take care of itself after some burn in.
I recently also purchased a DT990 pro and a DT1350. And, the Fostex's definitely sounds best straight out of the box.
