Introduced by Denon in 2014 as the Home Entertainment Operating System (HEOS), this wireless multi-room audio platform revolutionized home audio streaming by enabling seamless music distribution throughout homes via Wi-Fi networks. Initially launched as HS1 in 2014, Denon enhanced the system with the second-generation HS2 in 2016, adding advanced features and broader compatibility. HEOS technology is now built into every current Denon and Marantz receiver, creating an integrated ecosystem that connects multiple rooms and audio sources. The system supports high-resolution audio playback, streaming from services like Amazon Music, Pandora, TuneIn, Qobuz, TIDAL, and others, while offering advanced features like AirPlay 2, Bluetooth connectivity, and voice assistant integration with Amazon Alexa and Google Assistant. Controlled through the free HEOS app, the platform allows users to stream music, group rooms, and manage playback across entire homes, supporting both Denon and Marantz components along with dedicated HEOS speakers. As a proprietary technology platform rather than an independent company, HEOS represents Denon's commitment to wireless multi-room audio innovation, establishing itself as a leading solution in the connected home audio market.
