Query: Excellent sound for the price

I have several pairs of these, used with an iPod and a portable radio, occasionally my laptop. They are a great value, and have a smooth sound and good frequency range. The only drawback is that the wires could be more durable. I use them several hours a day, and it seems that the wires wear out from flexing and then I have to order another pair after a year or two.
