2 Turtle Beach headsets - work but flawed - or use for parts

I have 2 turtle beach headsets. Elite Pro2 with two new cords. this set has a cracked arm, which I did a crazy awful repair job on. They work fine but need the arm fixed. The second is the Elite Pro - The only similar TB headset that didn't have the arm crack. It was simply made better. The issue with this one is that I can only hear out of one side. May or may not be an easy fix. This set is more worn than the Pro2 because the Pro2 arm broke rather quickly. I purchased a second cord from the TB site costing me about $15 for the cord. It is included.
