GEAR4 has launched a 24W compact Bluetooth stereo speaker system known as the BlackBox. It's a glossy box whose hidden LED display springs to life when activated. Mobile phone compatibility requires downloading the right profile for your mobile from your computer. You can also do firmware upgrades via mini USB, and pack the speaker away in the carry case that's included when you buy. There's a remote control, too. It's £99.99 and you can buy online now.
