Doubling as an air purifier and high-fidelity headphones, the headpiece simultaneously delivers immersive sound through ANC over-ear headphones while directing purified air to the nose and mouth through a contact-free visor. Through 6 years of development, Dyson audio engineers equipped the headpiece with an advanced noise cancellation system and neodymium electroacoustic system delivering wide frequency response, precise left-right balance, low distortion, and rich uninterrupted sound.
