I purchased this product early February & I'm writing this review early October. I am now having trouble with the wiring where I have to play with the wires to try and get one of the headphones to work. Now, I've been using this 3-4 times a week IN THE GYM. I'd say that the lifespan on these headphones aren't too bad for the cheap price tag. Note that I sweat very easily and would do ALL my workout with iPod/headphones on. I'd definitely buy these again for gym purposes.
