Good headphones, good sound. Easy equipment. I turn on the headset, I turn bluetooth on my phone in 10 seconds is connected. By cons, it is not clear for calls, if we want to have to yell to others, I still prefer the phone in hand. What makes me lose 5 seconds each call time to choose the handset earpiece audio output. I also have some problems with the play / pause option. I wait a few seconds each time, I do not know if this is normal, if the helmet or if it is due to my smartphone but it's pretty boring after a while.
