They are USB charger supported which is nice and they are noise canceling so you cannot hear a thing and there is a button for that so you can activate it and deactivate it whenever you want to. 
There is also a mic so you can answer phone calls if you need. The bass in these are nice and deep and they just over all sound great. I love the fact that they do not die as quick as others so you can really use these all day if you wanted to.
These are great for work if you are looking for a pair. They come with their own little carrying sleeve and they do not slide off your head when you are wearing them they are a tight fit.
These are perfect for those who cannot stand loud noises, crowded places or just anywhere where people are talking loud or anything like that. These headphones will cancel it out and will allow them to be able to listen to their music and concentrate on where they are going without having a panic or anxiety attack while walking in a loud and crowded room.
I use these normally when I am gaming and have not had a problem with them at all.
Only thing about these is you cannot use the aux cable on them when they are off, they have to be on to use them.
