Why is the volume low when I connect my phone to the speaker via Bluetooth?
If "Reduce Loud Audio" is enabled in Headphone Safety, it may limit your Bluetooth volume. To fix this, go to Settings > Sounds & Haptics > Headphone Safety to adjust or disable the limit. Your speaker will then reach full volume output.
Why does the mention 400W, but the box says 40W?
The speaker's 40W rated power is for continuous use and optimal performance, while the 400W peak power indicates the maximum output during short bursts, like loud bass or dynamic music. Both ratings accurately reflect different performance aspects.
