Denon Home 400 — a compact wireless smart speaker with Dolby Atmos Music, HEOS multi-room, and AirPlay 2 in a neutral Stone finish.

The Denon Home 400 delivers high-quality stereo sound from a compact enclosure designed to blend into a modern living space. Dolby Atmos Music and DTS:X decode immersive spatial audio from compatible streaming services. HEOS Built-in enables seamless multi-room playback with other Denon and Marantz HEOS-enabled devices. AirPlay 2, Bluetooth, and Wi-Fi provide flexible source options, and a line-in port connects analogue sources. The Stone finish offers a warm neutral tone alongside the Charcoal variant (pid 42485).
