Harman International Industries has created the JBL Voyager, the world’s first portable speaker with an advanced subwoofer docking system. Perfect for regular travellers, detach the portable speaker and it becomes a wireless Bluetooth, go-anywhere, hi-fi speaker with a built-in SoundClear echo and noise-free speakerphone. An aux-in audio jack and USB port for charging smartphones and tablets makes the device even more user-friendly, while the portable speaker features custom drivers, and a lithium-ion rechargeable battery that gives five hours of uninterrupted playtime. www.jbl.com
