The TWS feature allows you to connect two Technical Pro 8 Inch Portable Bluetooth Speakers for a true wireless stereo sound experience. Note: Only two speakers can be connected via TWS at the same time.

Maintenance
1. Cleaning:
Wipe the exterior of the speaker with a soft, dry cloth. Do not use abrasive cleaners, waxes, or solvents as they may damage the finish. Ensure no liquids enter the speaker's openings.
