These headphones are the best of the best quality is impeccable crystal career sound even a little bit of noise, cancellation or how many people would say noise isolation but still the thing that most impressed me the most is the battery life I can go on for weeks and weeks, probably in months without charging these with I'm going to use or use them sometimes putting them down for hours later and then we used them in the battery is still at 100. The battery is basically the most important for me than any product that I buy and these I'm telling you are the real deal for the amount that they're selling is in dresses but they're selling something of this caliber, highly recommended you should buy.
