The Left side of my headphone is not working

"Hello....I have a problem

I use JBL headphones.

I accidentally pulled the wire really fast and then I couldn't see the earphones mark anymore

I can hear from the phone and one side of the earphones at the same time.

The wire also have a strange curvy spot....I think something is broken

(Sorry for bad English)"

@joshanjoy there is a crossover cable from one driver (speaker) to the other, check that out. Use a multimeter and check for continuity. Also check the solder connections on the driver (speaker) make sure the cable is still soldered on.
