JBL's Xtreme and Flip 3 portable wireless speakers were both leaked ahead of their official release by a European consumer electronics retailer. The company's Xtreme model looks to be the most rugged of them all featuring a resilient nylon fabric mesh similar to the UE Megaboom, which is described to be durst, mud and water-resistant. The Xtreme borrows some key features from JBL's Charge 2+ while enhancing them even further such as dual USB ports for charging external devices, a long-lasting 12 hour battery life, on-board speakerphone functionality with an echo & noise-canceling microphone – as well as two large side firing bass radiators that accompany what looks like four front-firing speaker drivers for a total of six drivers. That's two more drivers than what is currently found on the Charge 2+, so hopefully we should be able to hear the difference in sound quality.
