Dyson Introduces Air-Purifying and Headphones All-in-One

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 that 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 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 are exposed to long-term noise exposure above WHO guidance.

 

Jake Dyson, Chief Engineer said “Air pollution is a global problem – it affects us everywhere we go. In our homes, at school, at work and as we travel, whether on foot, on a bike or by public or private transport. The Dyson Zone purifies the air you breathe on the move. And unlike face masks, it delivers a plume of fresh air without touching your face, using high-performance 
filters and two miniaturised air pumps. After six years in development, we’re excited to deliver pure air and pure audio, anywhere.”

 

The Dyson Zone air-purifying headphones are borne of Dyson’s 30 years of expertise in airflow, filtration and motors technologies and a 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 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 by 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 the artificial lung.

 

Precision-engineered compressors within the earcups draw air through the dual-layer filters, intelligently designed to fit within the considerable space constraints of a headphone. The negatively charged electrostatic filter media captures ultrafine particles such as allergens, and particles from sources such as brake dust, industry combustion and construction whilst a potassium-enriched carbon layer capture city gas pollutants like NO2 and SO2. The compressor channels the purified air to the wearer’s nose and mouth via the contact-free visor, formed with flexible returns that channel the flow of purified air to the wearer’s nose and mouth.

 

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 by extensive listening trials. The result is 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.

 

The Dyson Zone air-purifying headphones have been engineered by teams across the UK, Singapore, Malaysia and China, with a particular focus on software on our South East Asia campuses. The app development and integration was a critical project to ensure a smooth connection journey and provide intelligent, meaningful air and noise pollution tracking features. Robustness and durability are central to a product that leaves the home with the wearer. 

 

The Dyson Zone air-purifying headphones full product specification and further details on local availability will be announced in the coming months. Timings will vary by geography.
