Connect wirelessly from a distance - Pairs with smartphone, tablet or other Bluetooth-enabled device. Rechargeable battery with up to 8 hours of charge. Built-in microphone - accepts hands-free calls through the speaker. Charger is included! Flaws: lightly used as a beach speaker, there fore there is some sand in the grooves and if you look closely some color damage to the front of the speaker. From what I have listened to, it doesn't seem to have affected the sound at all. I have a video on my story of the quality of the sound.
