Well received the DT770 Con 250ohm '05s today. They're a decent deal at the current price, but would suck anywhere approaching normal street, let alone MSRP. Not burned in, but even granting improvement will be behind several sub $200 closed cans including the A900 and HFI780 (two favorites around here I know!). Certainly congested and soft on top (while somehow also being peaky), but indeed several steps above the V6 and HD280, which I suppose are the competitors at the now $108. Weird phones, 'cause if they had a lower impedance they'd make decent carrying around phones. They're fine sounding for on the go, etc. Course you add an amp and the expectations and uses change.
