I have had these headphones for 3 months now and have been amazed by them. They work with my NOKIA N95 just great for music streaming with good controls and sound quality, also making and receiving calls. I have also used them with my PS3 For chatting to friends allover the world. You have no worries with battery life, they last all day and still have power in reserve. However the phone tends to go flat when you constantly stream music from it but i carry an emergency charger to cover the phone. They look ace and all my friends want a set once they try them out. They are very comfortable to wear and very light. When not in use they will hang around your neck, but this does not happen very often as you find yourself just turning down the volume. When you get a call they switch strait over and people think you have gon mad when you start aparently speeking to yout self, COOL!
