The Bluetooth earphone comes with a mobile power device and a mobile phone case. It makes it easy to carry, and you will never forget anyone of them anymore. The earphone can be charged while the phone is being charged. When receiving a call, users
don’t have to interrupt what is happening on the screen. They can just answer it with the earphone. Neither do the users have to turn on the hands-free speaker and break their privacy. It can also be used for causal music listening. When the phone or Bluetooth is done with charging, you can turn o the mobile power to save energy.
