As Bragi CEO Nikolaj Hviid slides his personal pair of Dash earbuds across the table, he promises they’ve been properly cleaned. I open up the textured black box, and pull two earbuds out of their charging case. One goes in my right ear, the other in my left; there are no wires, there’s no power button. At first, I don’t put them on correctly, so Hviid reaches out and presses the right bud a little more snugly into my ear canal. It dings brightly—it’s connected. I reach out and tap once on my right ear. Adele’s “Hello” starts playing. It sounds fantastic.
