I wonder if there is a mod to acoustically attenuate 3kHz region by approx 1dB, it's not a fault per se, but it's probably the only region that sticks out.

:thinking: 2000 hours of 8hr daily use seems fair for any kind of pads. Also I replaced them not because of wear, but due to the fact I managed to get a new pair for free. The feel was different on the new ones for sure, yet the old pair would keep going as usual

Yes it should be possible.

roughly same sound here on all 3 pairs, same mods, first one sounded initially different after 2000 hours, but new pads fixed it

Where are you based? I can make a straight cables, same way as I did for my 3 pairs of DT250, but I no longer have any spare connectors Pinout is available in service manual, or you can check it via DMM

For me, Dt250-250 are amongst the easiest to drive HPs, so much so, that I use them even unamped straight from DAP/Audio interface

Of course, they blossom with time :gs1000smile: 3 years in, 2500 hours, and still my most favourite pair of HPs, and I have tried many others, even several magnitudes more expensive.

Anything compressible should be better than nothing. :)

Bass till about 200Hz. There's a frequency response graph somewhere on the internet. You can also test through sine tones @50Hz

Yes, this is what I do and it definitely helps. Next level would be to use plastic sealant on the tip of the screw.

OK, then I would say there won't be any issues. It's the edge of the connector and sealed screw hole that creates the seal. Even with all 7 pins in place, there isn't a good seal, because springed contacts aren't particularly good at keeping vacuum :smile_phones: Just seal it the same way as 7...

Channel imbalance? No. It'll either work fine, with both sides connected properly, or not work at all. Not sure how this 6pin connector looks like, but the pinout used to be listed in service manuals.

Just when some of you weren't convinced that DT250 are the best HP. :o2smile: https://reference-audio-analyzer.pro/en/report/hp/beyerdynamic-dt-250-250.php Perfect immunity to variable output impedance (less than 1dB @ 300Ohm), or the near perfect conformity to ISO 226-2009 curve

I'm still using the same cable, Van Damme Miniature, which means it must be good. :beyersmile: I don't expect any sonic changes out of it, so I haven't heard any. But it's 10 times stronger when running a chair over it. It's definitely better than the stock one, which became stiff and hard just...

I still have one spare plug if you still trouble finding it.
