Have you ever faced the situation that you cannot share music with friends if there is only a pair of headphones? Then our "Earphone Speaker" can solve the problem! The earphone has a mini speaker attached. People can choose two different modes. Sharing Mode: the speaker is turned on then people can share music together openly. Privacy Mode: people turn off the speaker and use the earphone as a normal one. There is a small button on the earphone so that it is quite convenient to switch between two modes.
