#1byoneWirelessHeadphones I received these headphones free and have really enjoyed are of very good quality and have a spectacular audio. I am currently doing exercises and allows me to be free to carry out. It has magnets on both sides that allows me to close them around my neck when not in use. It has a USB port for charging. The battery is very durable first my cell is discharged to the headphones of very high quality is best. It connects via Bluetooth. 100% recommendable. http://www.amazon.com/1byone-Bluetooth-Wireless-Headphones-Ergonomic/dp/B013HEK7Q2
