So I wanted to you use these a few times before writing about them. I have so many headphones and you have to be sure of the differences in them. These headphones are really unique. They have great nooise cancelling technology that actually has a rechargeable battery attached to it. You can turn this feature on and off. However, once it is on you literally hear minimum background noise. With the batter charged to this via USB, you can literally use it maybe 18-20 hours depending on your first time charge. Don't confuse this with the actual use of the heaphones though. You can use them anytime via the wired jack required to use them. The battery is only for the noice cancelling feature. On the same location you find the noice cancelling feature, you find the call answer/end button, where the mic is located, and the noice cancellation light indicator. The headphones are adjustable in height, lightweight, foldable, and very comfortable. The actual ear muff foam is very soft and plush to your ears. The bass is even better than I thought it would be, I do believe the noise cancellation helps with that. Overall, I would definitely buy another pair for each of my children for Christmas. It says for children I believe, but they fit my head just fine.
