Query: Good for a month and then they broke

It was disappointing to have them break after only a month of usage. Out of the blue the microphone stopped working. They were pretty low quality for the money. The band that sits on top of the head is very cheap vinyl type plastic. The part where the cables split out of the main cable to plug into the back of the computer is very flimsy. I am disappointed at the shoddy craftsmanship of these headphones and would not recommend this product.
