Query: Volume knob broke in a few months!!!

They look great and the sounds isn't bad when the volume controls worked. Unfortunately now, the volume knob doesn't work anymore and I can only get sound if I push on the knob REALLY hard. The worst thing is that it won't incrementally increase or decrease the volume, it is either off or on EXTREMLY loud. I recommend getting something that is rated a little better! Keep doing your research before you buy.
