A pair of new Bowers & Wilkins receivers named Formation Audio and Formation Duo are listed as "coming soon" in Apple's recently updated list of HomeKit and AirPlay accessories. Bowers & Wilkins releasing receivers is interesting in itself, as the company is better known for high-fidelity speakers and headphones.
Bowers & Wilkins has yet to announce the products, but we did find a cached GDPR-related fair processing notice page on its website from December 2018 that mentions a line of Formation products, including the Formation Duo, Formation Audio, Formation Bar, Formation Wedge, and Formation Bass.
AirPlay 2 would allow the receivers to work with other AirPlay 2 devices such as the HomePod, the Apple TV, and Sonos speakers. AirPlay 2 receivers also appear in Apple's Home app across iPhone, iPad, Mac, and Apple Watch.
