Adopt the advanced Bluetooth 5.0 technology. A specific touch control function makes it more convenient, tap once to play/pause music and answer calls, and tap three to skip forward/backward. You can easily control it without operating the phone. The left and right ears are separated and can be used alone. Pick up 2 headsets from the charging case and they will connect automatically, then only one step easily enter the mobile phone Bluetooth setting to pair the earbuds. After the first connection, each use will be automatically paired, so there is no need to wait for a long time. The headphones are widely compatible with most devices with built-in Bluetooth.
