About this item: 
The new acoustic architecture replaces Move's single tweeter with two, unlocking a higher-fidelity stereo soundstage with crisp vocals and detailed instruments. With deep, dynamic bass powered by the precision-tuned woofer, you'll feel the emotional charge of a live performance. 
With automatic Trueplay tuning, Move 2 continually optimizes the sound for its surroundings. So, no matter where you are or what you play, you get the best listening experience. 
Listen twice as long as with the previous generation. All the acoustic updates work in concert for increased efficiency, giving you up to 24 hours of playback on a single charge. 
Shock absorbent materials protect against accidental drops, and the IP56 rating ensures spills, splashes, rain, dirt, and dust don't dampen your listening experience. 
Use the built-in handle to bring your music from one place to the next. When the battery needs a boost, set Move 2 on the included Wireless Charging Base, upgraded with a detachable power cable and more compact adapter. Charge on the go with any USB-PD power supply.
