• Power On: Press and hold the power button for approximately 3 seconds.
• Power Off: Press and hold the power button for approximately 3 seconds.

4.2 Audio Playback

• After successful Bluetooth pairing, open your preferred music or audio application on your connected device.
• Audio will automatically stream to the Nillkin Bullet S2 speaker.
• Volume Control: Adjust the volume directly from your connected device. The speaker itself may not have dedicated volume buttons.
• Play/Pause: A short press on the power button (or a dedicated play/pause button if present) may control playback.

4.3 Remote Photography Function

The Nillkin Bullet S2 can act as a remote shutter for your smartphone camera.

1. Ensure the speaker is paired with your smartphone via Bluetooth.
2. Open your smartphone's camera application.
3. Press the designated button on the speaker (often the power button or a specific remote button) to trigger the camera shutter.

4.4 True Wireless Stereo (TWS) Connection

If you have two Nillkin Bullet S2 speakers, you can pair them together for a stereo sound experience.

1. Ensure both speakers are powered off and fully charged.
2. Power on both speakers. They should enter Bluetooth pairing mode.
3. On one of the speakers, double-press the power button (or a dedicated TWS button if available). The speakers will attempt to connect to each other.
4. Once successfully paired in TWS mode, one speaker will act as the master and the other as the slave. The indicator lights will reflect this (e.g., master flashes for device pairing, slave is solid).
5. Now, connect your smartphone or audio device to the master speaker via Bluetooth as described in Section 3.2.
6. Audio will now play in stereo through both speakers.
