The mic on this headphone is AMAZING. I've purchased other headsets where people tell me it sounds like I'm talking in a tunnel. Then, I do the Skype test and I see what they mean. I use this headset and it's simply amazing how clear people can hear me. In my business that's ABSOLUTELY KEY. I feel bad I had to go through five other headsets to learn this information about the mic. I even tried the Sennheiser PC 360. And, the mic quality was better than that headset. On the Sennheiser people told me it sounded like I was in a "tunnel underwater." That's not good when the no. 1 thing I need to a headphone is to communicate.The sounds quality is very nice. Anyone who says the sound quality of anything but a "dedicated headphone" is terrible is simply exaggerating. I've played multiple difference instruments. If you put a blindfold on 100 people and asked them which one is the "dedicated headphone" just for music, it's proven most people don't know the difference.Comfort levels are superb. On other headphones with little round ear pieces may hurt if you have glasses or might even feel too small. Headphones like the Sennheiser PC 360 with its ear pieces are comfortable but this one is even more comfortable. Just give it a few days to break in.One thing I don't like about this headset is the Closed acoustics. That means when I'm wearing these headphones I can't hear things going on in my house. This can be a positive and a negative. If you are in an environment with lots of outside sounds you want to avoid, this is good. I notice I can't hear myself when I'm talking on the phone as well as a headset with Open acoustics. But, I can hear myself well enough so I don't feel like I have to yell.People who say the sound on this headphone is crap recommend getting a desk mic with a "dedicate headset" just for music. For me, this suggestion is absurd. I'm someone who doesn't need "perfect sound" like I'm at a concert in London. I need to communicate and have that communication clear. This headset does that PERFECTLY for Skype and my HTC phone. Probably would work with a Iphone as well.And, there's the cool factor with this headset. It just looks and feels really very cool.
