The battery gives you 6 hours play time from a full charge. Charging takes less than 3 hours, and is easy via the included micro USB cable. Bluetooth connectivity Pairing with your Bluetooth device is simple. Just power on the speaker and it's ready to pair. The wireless range is 10 m. Anti-clipping function Anti-Clipping lets you play music louder and keeps its high quality, even when the battery is low. It accepts a range of input signals, from 300mV to 1000mV and keeps your speakers safe from damage by distortion. This built-in function monitors the musical signal as it goes through the amplifier and keeps peaks within the amplifier's range, preventing the audio distortion caused by clipping without affecting loudness. A portable speaker's ability to reproduce musical peaks decreases along with battery power, yet anti-clipping reduces peaks caused by low battery, keeping music distortion free.
