Surprised at such excellent reviews. The noise cancellation is very good. But I'm disappointed in almost everything else. I'm 46 years old and the tuned sound didn't help me; Apparently my hearing is good as there was no sound in the test that I couldn't hear at the levels tested. The headphones make loud obnoxious Bluetooth-style beeps when on, plugged in, etc. But worst of all is the microphone. I thought the plug-in mic would finally offer good quality for phone calls, but that's nowhere near acceptable. Sounds terrible. Not even good enough for calls that don't matter, like calls to a credit card company. For business, forget it. I've tried calling paired to an iPhone, as well as Skype connected to a MacBook. The wearing comfort was just ok. The resizing step is too big; The right size for me was somewhere in the middle between the two. There's also no red light on the microphone to mute the audio, and the controls aren't as intuitive; For example, headphones have a mute switch that doesn't work when a microphone is plugged in.
