This little earbud has awesome sound and is very easy to use. Pairing it was very easy and the run time for it is excellent. I have listened to my favorite music for hours and it still has charge. Charging it is simple and fast. I love the one earbud because I can listen to music and answer calls all while being able to interact with my kids and family if they need me. You don't have to carry another device around with you this earbud has a wide range of reception from the device it is connected to. A+++++++++
