It's time to live loud! The portable waterproof JBL Xtreme 4 speaker delivers next-level JBL Pro sound with incredible dynamics, even at the highest volume, thanks to its two powerful woofers and two tweeters. The passive dual pumping JBL radiators provide deeper bass that moves you. Want to take your music on the go? The convenient shoulder strap makes it easy, while the durable rubber bumpers and the waterproof and dustproof IP67 rating mean that a sudden downpour or a plunge into the lake won't stop the fun. When it's time to create an even bigger sound experience, connect two Xtreme 4 speakers together for stereo sound. Or for your next party, use Auracast to connect the Xtreme 4 with any compatible JBL portable speakers, so that your friends relaxing by the pool can listen to the same playlist as those chatting indoors. Up to 24 hours of playback and a convenient power bank for this device means no need for recharging until morning. All of this, plus they are made with recycled plastic and recycled fabric. The JBL Xtreme 4 brings exciting sound with you everywhere
