SINOBAND Book Bluetooth Speaker
Quick Start Guide
1. Warning ⚠️
There may be noise when playing songs with strong bass when the battery is low. This is a normal phenomenon. Please ensure that the SINOBAND Book has enough power to maintain performance.
Prolonged use of the machine at high volume may cause damage to your hearing.
The SINOBAND Book has a built-in lithium battery. Do not use any fast charger exceeding 5V/3A, such as PD fast chargers, mobile phone fast chargers, Qualcomm fast chargers, or gallium nitride fast chargers. The voltage of these chargers may not be recognized or compatible with the motherboard.
Do not expose the device to sunlight, fire, or similar overheating environments.
2. What is TWS?
TWS means True Wireless Stereo. It allows two Bluetooth speakers to be paired and play music synchronously.
How to pair your device?
- Please ensure these two speakers are disconnected from other Bluetooth devices before turning them on. Then, turn them on.
- Select one of the speakers and short press its TWS button [?] to enter TWS pairing mode; the yellow light will flash.
- After successful pairing, the yellow light on both the master and slave devices will remain on.
- Turn on the Bluetooth on your device (mobile phone), find "SINOBAND Book" in the list, and connect.
- For speakers that have been successfully paired with TWS, they will quickly connect and pair automatically when turned on in the future.
- In TWS mode, short press the TWS button [?] to disconnect pairing mode.

9. Performance Optimization
The speaker's usage time depends on the volume and the type of songs played. Playing music at high volumes or with deep bass will increase battery consumption.
To safeguard speaker components and optimize battery life and playback duration, the SINOBAND Book adjusts the tone balance (including bass, treble, and vocal frequencies) when operating at maximum volume. This results in a noticeable difference in deep bass intensity between maximum and medium volume settings.
SINOBAND recommends using a medium volume level for listening to achieve the best sound quality and battery performance.
