The JBL Xtreme 4 portable waterproof speaker provides new, massive JBL Pro Sound sound with amazing dynamics, even at maximum volume, thanks to two woofers and two tweeters. Double JBL passive radiators provide deeper bass. Want to take your music outside? A handy shoulder strap makes it easy to carry, while the rugged rubber edges and IP67 water and dust resistance rating mean a sudden downpour won't stop you having fun. When it's time to create an even bigger audio experience, pair two Xtreme 4s for stereo sound. Or at your next party, use Auracast to connect the Xtreme 4 to any compatible JBL portable speaker, so your friends lounging in the garden can listen to the same playlist as those chatting in the apartment. The 24-hour playing time and the device's convenient power bank mean that you don't have to recharge it until morning. The speaker is made from recycled plastic and recycled fabric. JBL Xtreme 4 brings exciting sound with you - anywhere.
