Pairing the earphones with ESmart Connect
Important: Before pairing or connecting the headset to the application, you need to have your phone's GPS enabled.
Note: *For operating system security reasons, the earphones must be connected manually via Bluetooth® connection in the phone's Bluetooth functions menu when using iOS devices. If this is not the case, the earphones will not be able to connect to the app.
Almost all Android devices support "one-click configuration", and will connect to the earphones directly via Bluetooth® connection using ESmart Connect. Otherwise you will need to pair the earphones to your device manually via Settings > Bluetooth.
On the app home screen, tap the "Add device" button to start the automatic search. When your Earphones Style 4 are shown, tap the Add button to download the menu for the model (Earphones Style 4). Tap on the Done button when the model interface has finished downloading. The product interface will appear, showing a pop-up window to pair the earphones with the phone.
Manual pairing (altenative method)
There is an alternative method for manually pairing your earphones. To do so, select "Add" and follow the app's instructions for manual pairing.
Finally, both automatic and manual pairing add your earphones to the application.

Be sure to then tap Save and create a new preset in the list with your chosen name.

The Charging indicator (charging case) (5) flashes white and switches off once the charging process is complete.
Charging case

Important: We recommend not leaving neither your Earphones True Wireless Style 4 nor your charging case unused for long periods of time with an empty battery. We recommend charging the battery at least once a month.
