The danger of buying expensive headphones is that you run the risk of breaking a flimsy piece of rubber and metal, no matter how good the sound quality is. It turns out you can also fix the broken plug for a couple of bucks.
If you have the right tools (which include a soldering iron), you can strip the off the cord of a headphone and add a new plug to the end. The parts are cheap and can be a much better alternative than replacing expensive headsets. Instructions can be found at the source link below.
