In 2014, Denon launched a bold experiment: a new wireless audio platform, HEOS, short for Home Entertainment Operating System. What began as a small lineup of networked speakers has since evolved into one of the most trusted, integrated, and performance-driven systems in premium audio. Now entering its second decade, HEOS has become a standard in itself. And with a firmware update rolling out on September 17, the platform enters a new chapter, with a new name to mark its evolution: Powered by HEOS™.

A Timeline of Progress

2014 – Foundational Launch
Denon debuts HEOS with three wireless speakers: HEOS 3, 5, and 7. These products introduce multi-room streaming via dual-band Wi-Fi and a proprietary mobile app, targeting ease of use without sacrificing fidelity.

2015 – Ecosystem Expansion
HEOS 1 and the optional Go Pack introduce portability, while the HomeCinema sound bar/subwoofer combo brings TV audio into the wireless fold. Streaming services like TIDAL and iHeartRadio are integrated.

2016 – High-Resolution Audio and Bluetooth
Second-generation HEOS devices (HS2) arrive, adding Bluetooth, hi-res audio playback (up to 24-bit/192kHz), and 5GHz Wi-Fi for enhanced performance.

2017–2018 – Full AV Integration
HEOS becomes embedded in Denon’s X- and S-Series AV receivers, and later in Marantz and Classé products. The world’s first 13.2-channel AVR is launched with native HEOS support.

2019–2023 – Platform Maturation
The ecosystem grows across multiple categories, including integrated amps and multi-channel soundbars. Firmware updates refine app control, expand streaming options, and optimize performance.

2024–2025 – Rebranding and Firmware Evolution
HEOS is reintroduced under the “Powered by HEOS™” identity. The September 2025 firmware release introduces a redesigned app experience, user profile support, improved network stability, and an enhanced onboarding flow.

A Platform Built on Hi-Fi Heritage

HEOS was created by Denon, a brand with over a century of expertise in high-fidelity sound. This legacy shaped the foundational vision for HEOS: to deliver uncompromising audio quality in a wireless, app-controlled, multi-room format. From its first-generation speakers (HEOS 3, 5, and 7) to today’s comprehensive lineup of receivers, sound bars, and amplifiers, HEOS has consistently prioritized sound performance without sacrificing simplicity.

Today, more than 5 million products are Powered by HEOS, offering seamless audio integration across Denon, Marantz, and Classé products. This cross-brand integration enables users to unify multiple audio components under one intuitive control system—creating consistent, high-quality listening experiences across a wide variety of listening environments, from compact apartments to expansive multi-room homes.

Designed for the Modern Listener

The modern listener expects more than just great sound. They expect fluidity, customization, and immediate access to music across platforms. The latest HEOS experience, including updates introduced in HEOS 3.0 and the 2025 firmware release, delivers:

• Intuitive App Control: A redesigned user interface for effortless navigation, device grouping, and source selection.
• Personalized Listening: Support for individual user profiles, playlists, and room presets.
• Effortless Setup: Four-step onboarding that requires no technical expertise—simply plug in, connect, and stream.

One of the platform’s defining strengths is flexibility. With over 50 products from Denon, Marantz, and Classé now powered by HEOS, users can build systems tailored to their space and preferences. Here’s how:

• Start with a single wireless speaker or soundbar.
• Expand to a full home theater with multi-channel AVRs.
• Scale up to 32 independent audio zones throughout a property.

This scalability is backed by wide format compatibility (DSD, FLAC, ALAC, MP3, and more) and robust connectivity options including Wi-Fi, Ethernet, Bluetooth, USB, and AirPlay 2.

Looking Ahead: The Powered by HEOS Identity

The new branding initiative—Powered by HEOS™—signals a mature, unified identity that underscores the platform’s role as the core engine behind some of the most respected audio brands in the world. With ongoing firmware support, expanded app features, and a focus on user experience, HEOS continues to set the bar for wireless, multi-room audio.

From its origins as a disruptive idea in 2014 to its current role as a pillar of the modern audio landscape, HEOS has undergone a remarkable transformation. As it enters its second decade, Powered by HEOS™ embodies not just longevity but leadership, delivering premium sound, modern functionality, and true freedom of choice for every listener.
