FAQ
Q1: How do I set up TWS pairing?
A1: Switch on both speakers of the same model; they will automatically enter TWS mode and connect in series without the need for any further action, and there is no need for manual pairing. Some brands support NFC one-touch pairing for later models; please refer to the product manual for details.
Q2: Is a 1-hour battery life sufficient?
A2: With a 500mAh battery, it offers approximately 1 hour of playback time, making it suitable for short periods of outdoor use or when stationary on a desk. For longer battery life, you can use the speaker whilst it is charging, or opt for a version with a higher capacity.
Q3: Is it compatible with Apple iPhones?
A3: Yes. Bluetooth V5.3 is backwards compatible and works with mainstream operating systems such as iOS, Android and Windows, allowing for easy connection with Apple iPhones.
Q4: Does the FM radio require an external antenna?
A4: No. The FM function utilises a built-in antenna design, allowing you to listen to local radio stations both indoors and outdoors. Signal strength is affected by geographical location; reception is generally better outdoors or near a window.
Q5: Can I play music whilst charging?
A5: Yes. It supports DC-5V power supply, allowing you to use the device whilst charging without interrupting the music, making it suitable for extended playback in fixed desktop setups.
