Great headphones for a great price, it鈥檚 not as good as beats Headphones or bose, but it cost more than 5 times less. Sound quality is high, battery life is good as well, noise cancellation not so good bus as I said I didn鈥檛 expect anything better for this price. It fits my head perfectly, I can do any activities, running, bicycling, hiking. Good headphones all around. Verified Purchase 2. I have multiple wireless headphones because I travel a lot. Occasionally I lose them between flights. So I stock up, because these headphones would cost twice as much at the airport. Solid premium headphone. No connectivity issue and battery lasts 18 hrs without charge. Not noise cancelling, but you get what you pay for.Customized Over Ear Bluetooth Headphones website:http://www.szgorsun.com/blueto....oth-headphones/over-
