You would think BRAVEN might take it easy for a bit after releasing so many speaker models over the past few months. Nope. After debuting the BRAVEN 600 (review here), 625s, and 650 portable aluminum Bluetooth speakers, they quickly released a more affordable plastic 570 and the tough BRV-1 speakers. Now, BRAVEN has just overshadowed those speakers with the monstrous BRAVEN 850, a direct shot at Jawbone’s successful BigJambox speaker. The speakers feature extended-range aluminum cone drivers with dual passive radiators which should fill a good sized room. The 850 looks exactly like the original 650, only pumped up on steroids. It’s more powerful (20 watts), more bigger (9.5″ x 2.75″ x 4″), more louder, more everything. It’s also more expensive at $299.99. The 850 features 20 hours of continuous wireless playback, built-in speakerphone, AUX port, SRS WOW HD audio, USB-powered built-in charger, and aptX Bluetooth. Like other BRAVEN speakers, the 850 speaker can be daisy-chained to another 850 for even bigger and true stereo sound.
