Got a pair exactly one year ago (USB connector) for work-from-home. I didn't care much about audio quality (I have no complaints, but I wouldn't know OK audio from good), but the microphone and noise cancellation שרק just incredible, both the insulation for my ears and the mic's cancellation of צט noisy home.My kid and pets are not at all quite, and our home is small. With these earphones on, all the noises in my home become a distant matter. Video games, playing with a ball, dog barks and crying. I can hear them, but distantly.Moreover, the mic, is something out of this world. I've tested using a drill, Dremel, sanding paper all in addition to said kid and pets. My co-workers say they couldn't even hear the drill at all. Essentially, anything that's not directly in front of the mic is almost non-existentIf you need to work in a noisy environment, these will make a huge difference
