My 2,5mm 140cm Beyer cable finally arrived today. They work great. And I agree with all that have commented that these cans love balanced.
I managed to grab the last cable from hifisound.de so they don't have it in stock right now.
But I also got a reply from Beyer customer support to contact the agent below. So if you're in an EU country that Beyer don't ship to, you can try contacting:
