Ever fancied getting in on the whole 'cinema sound in your home' experience, but been put off by the mess of cables that inevitably comes with dotting a load of speakers around your living room? The JBL Bar 5.1 system might be the answer.

Launching at IFA 2017,  it looks initially like a standard soundbar / subwoofer combo, but comes with a neat trick up its sleeve. The ends of the soundbar can be detached to act as standalone, rechargeable satellite speakers, effectively transforming the whole thing into a 5.1 surround sound system (if you count the soundbar as two distinct channels).
