Quick Repair

My son's Trust gaming headset developed an intermittent fault with the left earphone. Quick investigation revealed one of the connections had come loose. It didn't appear to have been very well soldered originally. A quick 5-minute repair and they are working good as new. 

This type of wire is what my father called Litz wire, but reading up on it that might have been incorrect on his part. My grandfather was a pioneering amateur radio operator and almost certainly used proper Litz wire for radio frequency working on shortwave. Anyway, it is a strong and flexible wire suited to applications such as headphones and microphones, but needs the lacquer removed and to be tinned before soldering otherwise you get a poor joint.
