(NEW) beyerdynamic DT 990 PRO 250 ohm - LIMITED EDITION

I want to start by saying that these are good headphones that I would recommend, but they have one inexcusable build quality flaw that Beyerdynamic knows about and has done nothing to address. At each end of the headband is a slider cover which retains the left and right can and contains the adjustability slider and is basically how the cans are attached to the band itself (I've included pictures for reference). These slider covers are crappy, injection-molded hollow plastic pieces that will crack and break apart when repeatedly subjected to stresses such as putting the headphones on and taking them off. While the name suggests that they are only covers, on the contrary they are structurally integral to the headphones. This is likely the part of the headphones that experiences the most stress and it's made of crummy, brittle plastic. Mine broke after about 2 years of daily use and this renders them basically useless until the covers are replaced. Beyerdynamic knows that this is a failure point on these headphones because they sell a repair kit which is occasionally out of stock. CAD files that allow you to 3D print these pieces from more durable materials have existed since 2015 and yet Beyerdynamic continues to make the covers in this inferior design from inferior materials. I cannot think of an acceptable explanation for why this clearly flawed design has not been changed especially on headphones that Beyerdynamic themselves market as "a sound, long-term investment." My advice is buy these headphones, but also immediately buy the upgraded replacement covers from a retailer such as CentralSound or just print yourself some higher quality replacements rather than waiting for your OEM units to fail. I don't have a printer so I went with the former option and with shipping it was the same price as buying replacement units from Beyerdynamic (~$30).
