5FAQ

Can't connect via Bluetooth?

Make sure the speaker is on and in pairing mode, and Bluetooth is enabled on your phone. If paired before, "forget" the device in your Bluetooth list, then search and pair again.

FM radio finds no stations?

Plug in the charging cable — it works as the FM antenna. In FM mode, long-press the play button to auto-scan.

How does TWS pairing work?

Power on both speakers, double-press the power button on either one, and wait for the pairing tone.

How long does the battery last?

About 10–13 hours at medium volume. Higher volume shortens playtime.
