TWS allows you to pair two identical speakers for stereo sound:

- Press the TWS button on one speaker. It will emit a tone and begin pairing.
- Once paired, the TWS button will light up.
- Connect your phone to the speakers via Bluetooth to play music through both.
Charging
The speaker requires a 5V / 1-2A charger (not included). Connect the provided cable to the speaker and a power source. Charging takes 4-6 hours. A red light indicates charging, which turns off when the battery is full. Avoid using the speaker at maximum volume while charging if the power source cannot provide sufficient current.
Safety and Maintenance
While the speaker is IPX5 water-resistant, do not submerge it. Keep the device away from fire and moisture. Do not attempt to repair the device yourself; contact an authorized service center. The battery capacity will naturally decrease over time with normal use.
