Powerful sound, always and everywhere - Finally turn up the volume! The JBL Xtreme 4 portable waterproof speaker delivers powerful, next-level JBL Pro Sound with exceptional dynamics, even at maximum volume, thanks to two powerful woofers and two tweeters. Two pumping JBL passive radiators produce a deeper, more engaging bass. Want to take your music outside? The handy shoulder strap makes it easy, while the robust rubber casing and its IP67-rated waterproof and dustproof design ensure that a sudden downpour or a dip in the lake won't put an end to the fun. If you need even more sound, simply pair two Xtreme 4s and enjoy stereo sound. For your next party, connect the Xtreme 4 to compatible portable JBL speakers via Auracast. Then your friends can chill by the pool to the same playlist as everyone else in the house. Thanks to 24 hours of playback time and a practical power bank for your speaker, you only need to recharge it in the morning. Plus, it's made with recycled plastic and fabric. The JBL Xtreme 4 delivers immersive sound - anywhere.
