2. Activate Bluetooth: On your device (smartphone, tablet, etc.), enable Bluetooth.
3. Select Device: In your device's Bluetooth settings, search for available devices and select "JVC HA-ET90BTB" (or similar name).
4. Confirm Pairing: Once connected, the LED indicator on the earbud will stop flashing and remain solid or turn off, depending on the model. A voice prompt may confirm successful pairing.

3.3 Fitting the Earbuds

The HA-ET90BTB earbuds feature a Pivot Motion Fit and 3-point support structure for a secure and comfortable fit, especially during active use. Experiment with the different sizes of ear pieces (standard and open type) to find the best fit for your ears.

1. Choose Ear Piece: Select the ear piece size (S, M, L) that provides a snug seal and comfortable fit. The open type ear pieces allow more ambient sound for safety in outdoor environments.
2. Insert Earbud: Gently insert the earbud into your ear canal.
3. Adjust Pivot Motion Fit: Rotate the earbud slightly to engage the pivot motion fit, ensuring the 3-point support structure rests securely in your ear. This helps prevent the earbuds from falling out during movement.
