The left side of the cable isn't producing sound anymore, must be broken. I need a new one now, which cables will fit and are between 0-20 euro?

My budget is 200-350 euro, for a box that has both things.   I'd like one that is praised by many users, as to not buy something that might not suit my tastes.   I listen 80% classical music, 20% metal.

Hello,   I browsed trough some threads but the land of heapdhones is too vast for me to comprehend without making my own thread.   I have a 200-500 euro budget.   I listen to music from the renaissance to Bruckner's symphonies, everything classical.   Thanks in advance.
