4.1 Charging the Speaker
Before first use, fully charge the speaker. Connect the provided Type-C USB cable to the speaker's charging port and the other end to a USB power adapter (not included) or a computer's USB port.

- Power On: Press and hold the Power button (U) for 2-3 seconds to turn on the speaker. The LED indicator will flash blue, indicating it's in pairing mode.
- Enable Bluetooth: On your mobile device, go to Bluetooth settings and enable Bluetooth.
- Select Device: Look for "NOTABRICK Ki" in the list of available devices and select it to connect.
- Confirmation: Once connected, the speaker will emit a confirmation tone, and the LED indicator will turn solid blue.
The speaker will automatically reconnect to the last paired device when powered on, if the device's Bluetooth is active and within range.
4.3 True Wireless Stereo (TWS) Pairing
To achieve 360° stereo sound, you can pair two NOTABRICK Ki speakers together:
- Ensure both NOTABRICK Ki speakers are powered on and not connected to any other Bluetooth device.
- On one of the speakers (this will be the primary speaker), press and hold the TWS button (often indicated by a double-speaker icon or similar) for 2-3 seconds. The speaker will enter TWS pairing mode.
- The primary speaker will search for the secondary speaker. Once connected, both speakers will emit a confirmation tone, and their LED indicators will synchronize.
- Now, connect your mobile device to the primary speaker via Bluetooth as described in Section 4.2. Audio will play through both speakers in stereo.
