JBL Xtreme is the ultimate portable Bluetooth speaker that effortlessly delivers earth-shaking, powerful stereo sound by incorporating four active transducers and two visible JBL Bass Radiators. Packing a massive rechargeable 10,000mAh Li-ion battery that supports up to 15 hours of playtime and dual USB charge out.
This is by far the best portable speaker I have ever heard. The instruments are crystal clear, bass is powerful just the way I like it, everything is balanced. Perfect for my jamming parties indoors or outdoors.
