The Sony SRS-BTD70 Bluetooth Speaker (Black) lets you wirelessly stream your favorite music on the go. The 2.1 stereo speaker arrays with subwoofer delivers surprisingly rich, full sound from a compact assembly. You can enjoy up to 13 hours of playback using three AA batteries, or connect it to an AC outlet for hours of uninterrupted sound.
For easy battery removal and replacement, the battery compartment clicks open and closed. And for your devices that aren't Bluetooth compatible, the system is equipped with an auxiliary audio input.
