Denon Home 400: A Stylish Sonic Leap
6 Jun
Summary
- Denon Home 400 offers adjustable Dolby Atmos spatial audio.
- It boasts a stylish, premium design with seamless fabric.
- Setup is simple via the intuitive HEOS app.

The Denon Home 400, released on March 24th, 2026, positions itself as a formidable competitor to premium wireless speakers, notably the Sonos Era 300. Priced at $599, this speaker distinguishes itself with native Dolby Atmos support and adjustable spatial audio settings. Users can customize bass, width, and height for a personalized immersive soundstage. Its design eschews prominent plastic for a seamless fabric finish and a sturdy titanium base, contributing to a sophisticated aesthetic that complements living spaces.
The HEOS app streamlines setup and offers robust multi-room capabilities, while connectivity options include AUX, Bluetooth, Apple AirPlay 2, and various streaming service integrations. Voice control is limited to Siri, requiring an existing Apple HomePod for setup. Sound quality is a highlight, delivering clarity across frequencies with significant bass oomph from its dual woofers. While the Auto mode offers an immersive spatial experience, a Pure mode provides a more traditional stereo sound for those who prefer it.
