Query: good if like buying new headphones every 6 months

Great sound for the price, good bass, and comfortable to wear. Sounds like a good deal until you realize why they're so inexpensive. The rubber surrounding the headphone wires just deteriorates after a couple of months. At first it was just a couple of openings and I figured it was because of misuse, but the deterioration got to the point where the entire rubber casing just totally came apart. Had to throw them away because they simply stopped working. I didn't listen to the reviews which stated the same thing, and now I'm paying the price.Not worth it in the long run, currently trying to find a replacement pair of headphones.
