What is it? This wearable 4K camera gives a great own-eye perspective on whatever it is you’re doing. Want to capture the moment as you make a parachute jump, abseil down a cliff face or ride a roller coaster? With the A500, you record exactly what you see. The camera unit sits on the side of your head, at eye level, while the ‘body’ of the camera can be strapped to your arm. When’s it due? Snap one up now. Why are we excited? 4K video and wearable tech are this year’s big things, and this dinky device combines them both. It could prove a real trump card to extreme sports fans, or anyone who wants a permanent memento of a once-in-a-lifetime experience. Watch Brazilian footballer and star of the World Cup, Neymar Jr, put it through its paces at youtu.be/C0vo5B92GgI.
