We’ll do just about anything to make the time pass while flying and now that includes putting together our headphones! The Phitek Nebula headphones arrive as a flat-pack packet that users can assembled and use for the duration of the flight and then take home. Because of the DIY nature of this design, users feel more attached which will expand the life cycle of the recyclable product. For the airline’s benefit, they’re extremely compact, taking up only a third of the space of existing headphones. Folded from a single sheet of .3mm A4 polypropylene the Nebula are also incredibly flat. Using a flat aluminum band to provide tension and structure when packed, at its widest it’s only 45mm wide.
