A new energy-saving lightbulb? A minimalist homage to Zippy from Rainbow?
No – this is one part of the new Aqua Soundz speaker system, combining a wireless transmitter you connect to your iPod with a floating receiver/speaker.
The system, which is now available for £40 from online retailer Gadgetshop, uses 863MHz wireless transmission to give a range of around 50m.
The transmitter connects to iPods and other personal players using a 3.5mm jack, and the system is said to deliver 'high quality stereo sound'.
As well as floating, the speaker can be used free-standing, or hanging using its integrated hook.
