Query: Seemed OK at first, Worthless in the end

While this product is comfortable and provided great sound quality initially, the left ear snapped off after a few months. The plastic in the rotation bearing is quite cheap. I was able to super-glue it back together, but now the volume control is on the fritz and producing static. When the control is used, it can fade in and out one or both ears. It also produces a lot of static at the low and mid level volume ranges. I must keep the volume all the way up on the headphones and control it from my computer.Skip this junk, find something else.
