  • Bass-driven sound: Builds on the HD 400S tuning to deliver punchy, engaging audio that keeps music and movies full and lively.
  • MEMS microphone: Uses a low-noise MEMS mic for clear, full-range voice pickup, which improves call quality and voice chats.
  • Portable and compact: Folds into a small footprint with an included storage pouch, so it fits easily in backpacks or bags.
  • Detachable cable: Comes with a removable cable that is simple to replace or pack away, helping the headphones stay tidy and organized.
