headphone repair

As attached in the pic, one of my sibling's AKG K92 3.5mm end broke due to bending it while removing it from their laptop -_- Can I simply cut the last few cm of the cable and solder a new aux cable end to it? Sorry if this comes off as a noob question, I have basic soldering skills but not sure...

Looking for basic solder work. Repairing a headphone jack, having a micro switch changed etc.

Need to get my Beyerdynamic headphones fixed. Sound is coming out of only one side. Looks like one of the connectors might need soldering. Was wondering if anyone knows any service center in Bangalore where they fix headphones. Have another Beats headphones which also need repairing.
