Perhaps one of the main complaints about the Beyerdynamic DT 770 Pro is the non removable cable. One of the most popular mods for the DT 770 is to install a removable cable. Some like to add a 3.5mm jack and myself, due to owning several other headphones with the same connector, I prefer to use a mini XLR connector.
In the video below I show how I modded my DT 770 with a mini XLR connector.
