The JBL Xtreme has four active transducers and two bass radiators, which JBL says produce a “powerful, stereo sound.”
It can be connected to multiple JBL Connect-enabled speakers, or even up to three smartphones at once.
It comes with a rugged, splashproof body, allowing it to be used safely outdoors, and a 10,000mAh rechargeable battery, which can last up to 15 hours. Its USB outputs can charge mobile devices as well.
The JBL Xtreme is available from July for £250.
