I accidentally broke the .8mm jack on my DT770 pro headphones, so I needed a fix. I advise getting this official cable rather than a cheaper alternative because the cables in this are colour-coded for an easy fix. An unofficial one will require you to get a multi-meter to confirm which cable to solder where.
The soldering job was relatively easy, even for someone like me.
The coiled cable is also an improvement on the standard cable, as now it doesn't get stuck on my desk chair leg.
