For 10 months of use, I can say that the microphone and sound were at the level of their cost, but someone will not like the way the headphones sit (even before the darling cracked). Because of this, you can forget about soundproofing, you hear what's going on in the house and hear your boys from dis. The plastic on the darling is worse than Chinese rubber, handled the headphones carefully, they were free of dust, scratches, were in limbo when not in use
