Wow these are amazing! They work so good and the sound is like you are at a concert. It's very powerful and they last for so long. I love these! They are a quick charge and they last for so long I don't have to worry about using them once and then having to recharge them! I can listen for hours and not a worry about them dying 1/2 way into a good song. I can watch movies and do so much with the life lasting in these. They came super fast and the price is amazing! I'm so happy with these I bought two of them and love them! I wil be buying more for gifts for family. They are so handy and easy to carry. I love these!
