Dyson Confirms 2022 Launch of Air-Purifying Headphones Delivering Pure Air and Pure Audio
The Dyson Zone™ is Dyson’s first wearable purifier, capturing city pollution including gas, allergens and particulate matter and cancelling unwanted noise with advanced noise cancellation and pure, high-fidelity audio.
Today, Jake Dyson has unveiled the Dyson Zone™ air-purifying headphones, Dyson’s first step into wearable technology. The Dyson Zone™ is a set of noise cancelling, high fidelity over-ear headphones which simultaneously deliver immersive sound to the ears, and purified airflow to the nose and mouth. The result of over a decade of air quality research and development, the Dyson Zone™ air purifying headphones simultaneously tackle the urban issues of air quality and noise pollution.
As the world’s urban population continues to grow, the World Health Organisation (WHO) estimates that 9 in 10 people globally breathe air that exceeds WHO guideline pollutant limits . Where NO2 pollution in cities decreased during the Covid-19 pandemic , levels have quickly returned to normal, or exceeded pre-pandemic levels across many global cities . It is estimated that more than 100m people, around 20% of the European population, are exposed to long-term noise exposure above WHO guidance.
6 years & 500 prototypes
The Dyson Zone™ air-purifying headphones are borne of Dyson’s 30 years of expertise in airflow, filtration and motors technologies and deep understanding of indoor and outdoor air quality. The compressors in each earcup draw air through the dual-layer filters and project two streams of purified air to the wearer’s nose and mouth, channelled through the non-contact visor. Sculpted returns on the visor ensure purified airflow is kept near to the nose and mouth and diluted as little as possible by external crosswinds. The Dyson Zone™ delivers rich, immersive audio and relief from unwanted city noise thanks to advanced active noise cancelling (ANC), low distortion and a neutral frequency response, to faithfully replicate music or audio as the creator intended.
Originally a snorkel-like clean air mouthpiece paired with a backpack to hold the motor and inner workings, the Dyson Zone™ air-purifying headphones evolved dramatically over its six years in development. More than 500 prototypes saw one motor initially placed at the nape become two compressors, one in each ear-cup and the evolution of the snorkel mouthpiece into an effective, contact-free visor that delivers clean air without full-face contact – a brand-new clean air delivery mechanism.
Developing a non-contact solution was a must for Dyson engineers, to avoid the discomfort and irritation often associated with full-contact alternatives. The visor, therefore, was a critical element. The airflow pathways and visor design are central to delivering pure air. The geometries of the visor and the visor returns, alongside the central mesh that diffuses the two jets of airflow, ensure that the purified air exiting the filters is effectively delivered to the nose and mouth in crosswinds, and for the wearer’s specific facial shape. Going beyond existing testing methods, Dyson engineers use a breathing manikin fitted with medical-grade mechanical lungs and sensing equipment, which ‘inhales’ pollution replicating human breathing patterns in a controlled chamber. They then measure the pollution level within the nose and throat to determine the filtration efficacy of those particles which would otherwise end up in Frank’s artificial lung.
A scientific approach
A first foray into the world of audio, Dyson engineers took a scientific approach, choosing not to rely on a ‘golden listener’ approach that many others do. Dyson’s team of audio engineers and acousticians sought to engineer excellent audio led by metrics, backed up with extensive listening trials. The result: pure, rich audio and advanced noise cancellation. Despite the space constraints inherent with a wearable device, Dyson engineers developed a high performing neodymium electroacoustic system within each earcup. A wide frequency response, precise left-right balance and distortion significantly below what can be detected by the human ear, offer a faithful reproduction as the musicians or creators intended.
Through solving a problem of Dyson’s own creation, the engineers have developed an advanced noise cancellation system. Together, the device’s passive attenuation and the ANC, with its unique array of microphones, reduce unwanted environmental noise and motor tones to provide advanced noise cancellation at home, at work and on-the-go. Large, angled ear cushions mould around the listener’s ear, with a foam density and headband clamp force engineered specifically for both comfort and optimal noise reduction.
