Listen to music for up to 18 hours with the JBL PartyBox 310 splashproof speaker. Its impressive battery life is great for a party. You won’t have to worry that you’ll need to stop dancing to plug it in. You can even play this outside, thanks to the IPX4 splashproof rating. This means splashes of rain or pool water won’t cause it any harm, allowing you to party no matter the weather. In fact, its dazzling lights sync to the beat of the music to provide an amazing background setup to any gathering. Also, the backlit buttons provide DJ control in the dark. The JBL PartyBox 310 is portable, too. Its stand with smooth-glide wheels allows you to take it wherever a party is calling you. And with the PartyBox App, you can control the party from your phone, including customizing sounds and switching tracks.
