What is it? The Ayo is a headset that uses a ‘special lighting solution’ to solve travel-related tiredness. It adjusts your hormone levels to help you sleep better and feel less jetlagged – without taking a slew of questionable pills and potions. When’s it due? Shipping December 2015 Why are we excited? It sounds like something you’d shout about to gain attention, but the Ayo will turn heads without you needing to say a word. Sorting out your sleep in just 20 minutes? It’s what frequent flyers have been, er, dreaming of.
