With a few months' research and development, this kind of bluetooth earphone is on the market. It is enjoyable that we can listen to music while doing sports. As it showed in the photo. You can operate the bluetooth earphone easily with the left earbud. There are a round multi-function button, and you can turn on/off the earphone by this button. Press the button +/- with one finger and volume can be up and down easily. You can also change to the previous / next song by the button +/- while you are listening to music. USB charging port and charging cable are offered. So you can charge the earphone conveniently. For more convenience, we add a small bag (as it shows in the photo) with the bluetooth earphone. It is big enough to hold a common cellphone. Just get one and you are sure to like it.
