About SonyHeadphonesClient
SonyHeadphonesClient is an open-source, cross-platform library and client implementation for Sony Sound Connect (formerly Headphones Connect) headphones. It provides native support on Windows, Linux, macOS and Web (Emscripten), and the client app is also published as a Progressive Web App at mos9527.com/SonyHeadphonesClient with what the project describes as full UI and feature parity with the other platforms.
The project is a spiritual successor to Plutoberth's original SonyHeadphonesClient. There is no release build yet, so users are pointed to nightly builds or the web version. Support for legacy v1 protocol devices such as the WH-1000XM4 and WH-1000XM3 is in progress, and device-specific support status is tracked in the repository's device-support documentation. The project states it is a personal effort and is not officially endorsed by Sony.
