More bass and volume for the music you love. Whether you’re partying, working out or just lounging around the house, enjoy a full-range stereo sound with impressive volume. Powered by MaxxBass technology and dual passive subwoofers, to make sure you never miss out on those ultra low frequencies. Unlike other speakers, Anker uses advanced Bluetooth technology to maximize device compatibility and pairing speed. A 5200mAh lithium-ion battery lets you play up to 160 songs over 8 hours at mid-level volume on a single charge-that’s pretty impressive for a speaker this powerful. At Anker, we believe in our products. That’s why we back them all with an 18-month warranty and provide friendly, easy-to-reach support.
