ESmart Connect App

Before getting started, you will need to download the ESmart Connect app to your Android device from Google Play [Google Play button], or from the App Store for iOS [App Store button]. This will let you set up and manage your Senshi Eco Earphones.

NOTE: If the app does not appear in your Play Store, you will have to download it directly using this link: here.

Setting Up Your Account

2. Go to the next page, tap on "Sign Up", and enter your phone number or email to register and get the verification code.

Pairing the Earphones

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 (alternative 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" [? Save button] and create a new preset in the list with your chosen name.

The equalizer interface displays a graph showing decibel (dB) levels across different frequency bands (e.g., 31 Hz, 62 Hz, 125 Hz, etc.), with adjustable points and a "Save" button.

A map interface is shown, indicating the device's last known location.

NOTE: All changes made to the earphones via the app are saved in their Bluetooth chip, meaning your device will keep its configuration should you later connect it to another device that does not support the ESmart Connect app.
