“Anyone who likes their music on the go has to decide whether they want quality sound like you get from over the ear headphones or if you want to go light and easy with earbuds and sacrifice sound for convenience. Design studio TECA has tried to end that struggle with their new handmade Luzli Roller MK01 headphones ($3,000) that offer exceptional over the ear sound quality but roll up like a metal link bracelet for stowing away in a pocket or backpack.”
