Ok, my brother bought a pair of broken beyerdynamic headphones from ebay, I have no idea what they are, just 600 oms.
Now he is mad that the 50$'s he spent went tward... a broken pair of headphones, and he refuses to do any diagnostics to find out whats broken.
from what I can come up with...
1) it could be the cable
2) it could be the cable through the headband
3) it could be the driver
Any one of these makes sense to me due to the many ways cheaper headphones have broken for me, however I have no way to test any of this.
Is there a way to know for sure without having a multimeter?
