Repairing Headphones

[faced]

I'm looking to get into electronics (just repairs for now)

my headset has been cutting out in one ear, it is a "Steelseries 5hv2"


Basically i wiggle the wire near where it connects to the actual headphone and if its a certain position it will work, but if its in normal use it won't...


now this headset has a microphone so i guess that would be another wire.

I'm quite new to electronics (I've soldered etc basic high school electronics) so if anyone could give me an essential list of tools + optional/very helpful ones that would be great.

So to sum it up-
- it works in the ear where the wire connects but not in the other one.
- need help getting all the right tools etc (whats the most economical way to get in a kit/pack?).
- maybe a basic run through/diagram of what to do?.

any help appreciated

Soldering iron, solder, and basic hand tools. There's a wire half broke probably near where it goes into the headset.
