So to begin – you pair it with your Bluetooth device; which is easy. Hold down the center button on top for several seconds and turn your device's Bluetooth on and presto, you're paired! Once your device is paired, the sound technology is surprisingly crisp. a.m.p. calls their technology the dBs1™ which is crisp, clear and hi-fi audio. I've had the speaker on for a few days now, I'm happy to report I haven't had to re-charge it once yet. Only time will tell if that continues, but I'm pretty impressed to date with battery life as well.
