Don’t be fooled by the ultra-slim style, the Sound Tower delivers surprisingly rich sound and deep bass, wirelessly! Beautifully curved into a smooth tube, the speaker is grip-friendly and easily slips into a backpack or purse. Bluetooth 4.1 technology ensures easy and reliable pairing, so you can enjoy up to 8 hours of hands-free music and calls anytime, anywhere. You can also connect with non-Bluetooth devices via the aux-in port or play audio files directly from a Micro SD memory card. Indoors or outdoors, wire-free or wireless, you deserve sound on your terms. Bold Look. Big Sound.
