Ninja Plugs were designed for music lovers who want to stay in their world without disrupting the one around them. The first “smart” headphones, they offer two options: a sleek plug that fits between your player and earphones or headphones with built-in sensors. Lucy pitched this innovative product live at Social Media Week’s The Greatest Idea Never Bought 2013 to an audience that included Cindy Gallop and team members from Spotify. Ninja Plugs weren’t just an idea—they were a vision for the future of immersive, seamless listening.
