So I dragged home the parcel with my, err, "new" HD424s today, threw 'em old earpads into the trash (classic CTD, or crumble to dust, syndrome) and put new ones on (interesting way of fastening btw), gave the cans a little cleanup and connected them to my surround amp's headphone jack (an adapter from this funky old DIN "Würfel" plug to 6.3 mm had thankfully been included in the auction). Yup, these are harder to drive than even the DT231s (but unlike with those it's a very high impedance that causes this), but I get a reasonable volume out of 'em without much trouble. My first impressions: These noticeably drop off in the bass and highs (the highs reach up to somewhat over 15 kHz, the bass reaches down to 40 Hz and below but does drop off in volume), thus are somewhat mid-centric. These mids, however, are fairly nice, if a bit on the bright side, with a wee bit (but no more) of sibilance. I grabbed the Shibatch Super EQ plugin for Winamp and tried to EQ things out, with the following result which sounds pretty acceptable to me:

Comfort wise, they're quite good for supraaural cans, as the earpads are fairly soft.
Now, can anyone say how old these are, approximately? My guess would be some 25 years? And is the impedance really 2 kOhm?
