4. Setup
4.1 Charging the Earbuds and Case
- Place the earbuds into the charging case. Ensure they are correctly seated; the LED indicators on the earbuds will light up to confirm charging.
- Connect the USB A-C charging cable to the charging case and then to a USB power source (e.g., computer, USB wall adapter).
- The charging case LEDs will indicate the charging status. A full charge provides up to 34 hours of total battery life (earbuds + case).
4.2 Selecting Eartips and Stabilizer Ear Fins
For optimal sound quality, comfort, and a secure fit, it is crucial to select the correct size of eartips and stabilizer ear fins.
- Eartips: Experiment with the 5 provided sizes (XS, S, M, L, XL). The correct size should create a good seal in your ear canal, blocking out external noise and providing rich bass.
- Stabilizer Ear Fins: Choose from the 4 provided sizes (XS, S, M, L). The fin should fit snugly into the concha of your ear, preventing the earbud from falling out during movement.
4.3 Bluetooth Pairing
- Open the charging case. The earbuds will automatically enter pairing mode (LEDs will flash).
- On your device (smartphone, tablet, laptop), go to Bluetooth settings and enable Bluetooth.
- Search for available devices and select "Yamaha TW-ES5A" from the list.
- Once connected, the earbud LEDs will stop flashing, and your device will confirm the connection.
- For subsequent use, the earbuds will automatically connect to the last paired device when removed from the case.
