I thought that Id try to use the warranty when I got around to it, and then lo and behold a week later, the headset controller buttons stop working in the beginning of the day, and the right earphone dies at the end of the day. Extremely comfortable, I have a desk job though do walk quite a bit throughout the day. its a bit far away from my mouth. Either I received a defective one or they are totally garbage! For the price paid I was a bit disappointed with the actual shoe part being made out of a plastic material, and that it can be slippery on certain types of flooring. Not a huge issue for me . Enfin, concernant cette application, il est possible également déteindre ou allumer lenceinte, de régler le son, modifier la langue de lenceinte (français disponible) et, le plus important à mes yeux, dutiliser un EQ sur la musique. They are pretty snug still but I think a 10 might be too loose so Im keeping them and hopefully wearing them will stretch them out a little. Shutting off the headset and powering them back on fixed it. They are useless except for listening to music with my phone in my pocket.
