Performance Build Quality Comfort Value PRICE $599 AT A GLANCE Plus 50mm biocellulose drivers Liquid wood ear cups Deliciously comfortable Minus Cable much too long for portable use THE VERDICT NightHawk’s use of sustainable materials, high comfort, and sweet sound bode well for AudioQuest’s debut headphone. Everything about the AudioQuest NightHawk headphone, from its materials, design, and sound, differs from what came before. Take a gander at those ear cups: They’re made from something called Liquid Wood. Don’t worry, they’re not the least bit squishy or soft. The cups are crafted from sustainable plant fibers that are liquefied and precision injection-molded. Then their insides are elastomer-coated to minimize resonance. The ear cups also feature a 3D-printed grille, inspired by the underlying structure of butterfly wings, and the grilles are said to reduce the cups’ internal reflections.
