Very good! January 1815

I use this headset model for several years; he perfectly isolated from outside noise and the price on Amazon is more attractive than other sites (as I use it every day, I am regularly called upon to change, by dint of not always delicate manipulations, "fake contacts "make their appearance after 6 to 8 months). I recommend to people "indisposed" for all ambient and proximity incivility in transport for example (ultra sonic telephone conversations to name a few ...) :-)
