I recently bought the newer model (and supposedly better) Logitech Wireless Headphones for MP3 (the black model - not the white one). Even though the sound quality is fantastic, the quality of the material used to construct the headphones is NIL. SUB-STANDARD. I cannot find a better adjective to describe the extremely poor material used. After little more than 2 months of intermittent use (2 times a week, each session lasting no more than 1 hour) the headphones have cracked right down the middle. With the wiring broken, the headphones are now totally useless. My advice to anyone thinking of buying the headset is, STAY AWAY FROM IT! You will be pouring your money down the drain. A word to the wise is enough ......Logitech must be ashamed of themselves for not fixing a problem that had been identified in the previous model. This is my first and certainly last time of ever buying a Logitech product.
