Review overview
Tom’s Guide’s reviewer rated the Denon Home 350 highly for its clean, powerful and immersive sound, understated premium design and easy operation. Responsive touch controls, a straightforward app and support for other HEOS-compatible devices make it a versatile choice for whole-home listening. Its main disadvantage is the substantial price.

Who it is for
The Home 350 is a smart speaker for listeners seeking high-quality streaming and multi-room audio. It retails for $749 / £599, putting it firmly in the premium category.
Price and availability

Part of the Japanese brand’s HEOS-powered hi-fi smart speaker range, the Home 350 uses Denon’s proprietary wireless ecosystem. At $749 / £599, it is the most expensive model in the Home family. It also costs more than two close rivals, the Bowers & Wilkins Zeppelin ($559) and Sonos Era 300 ($449).
The reviewer nevertheless considered the premium justified by its audio quality, appearance, accessible controls and broad connectivity.
Design and controls

Like the Denon Home 150 ($249) and Denon Home 250, the Home 350 has a soft fabric covering that wraps around the body, concealing the front, rear and side speakers. Its restrained styling gives it the appearance expected of an expensive home speaker.
This is a stationary speaker intended to sit near a power socket, not a portable model. Measuring 14.96 x 8.85 x 7.08 inches and weighing 13.88lbs, it is heavier than the Sonos Era 300 (9.9lbs), but lighter than the Bowers & Wilkins Zeppelin (14.33lbs).

There are no elaborate lighting effects. Instead, a small LED at the bottom changes color to indicate connection status. The touch panel lights up when a finger approaches it, and its six numbered buttons can be customized in the app. By default, for instance, button 1 selects aux input. Adjacent play/pause and volume up/down controls proved highly responsive in the review.
Bluetooth and power buttons sit on the rear between the input ports. The reviewer found them easy to reach and responsive, rounding out an intuitive control layout.
Multi-room features and voice assistants

The Home 350 requires a wall outlet and cannot operate without wired power, even though it supports wireless audio connections. Denon does not specify an IP rating, so the reviewer advised caution around liquids.
Another HEOS-compatible speaker can be paired with it for left and right stereo channels; that second speaker need not be another Home 350. In the review, pairing it with a Denon Home 150 worked successfully.

Multi-room setup requires the companion app but was straightforward. The reviewer observed excellent synchronization with no lag, and playback commands took effect immediately across the speakers: pausing the Home 350 also paused the Home 150.
Voice support includes Alexa, Google Assistant, and Siri via AirPlay 2. The reviewer appreciated using the Home 350 to check the time and set reminders, particularly while cooking or playing video games, without repeatedly reaching for a Google Pixel 7 Pro. Although the reviewer owned an Amazon Echo Dot Gen 3, it was not used frequently.
Connections and the HEOS app

Bluetooth lets the Home 350 connect to smart devices and Bluetooth-enabled turntables, while built-in 2.4/5GHz Wi-Fi supports multi-room listening. Wired options include a 3.5mm aux input, a USB-A port for music stored on a thumb drive, and an RJ-45 Ethernet port on the rear. The review notes that these physical connections are absent from both the Sonos Era 300 and Bowers & Wilkins Zeppelin.




The free HEOS smartphone app is available for Android and iOS. Its clean interface was easy to navigate in the review. It is needed to build a multi-room system with other HEOS-compatible devices, such as the Denon Home 150, and also provides equalizer adjustments.
Integrated streaming services include Qobuz, Spotify, Tidal, Amazon, Pandora, Tune-In, and SoundCloud. Listening does not require a continuous Bluetooth connection to a phone, so playback can continue without the smartphone remaining in range.
Sound quality

The Tom’s Guide reviewer placed the Home 350 among the best-sounding speakers they had tested, praising its balanced, full presentation and strong performance across genres. In both a living room and the testing lab, it delivered substantial volume and room-filling sound even at 45% volume.
Its six-driver arrangement comprises two 1-inch tweeters, two 2-inch mid-range drivers and two 6-inch woofers, powered by six class D digital amplifiers.
Listening tests used familiar songs streamed from Qobuz over Wi-Fi. The Home 350 supports gapless high-resolution playback up to 192KHz/24-bit with FLAC, WAV, ALAC, and DSD 2.8/5.6MHz formats. The reviewer heard a consistent presentation from different positions in the rooms, crediting the DTS Neural:X upmixer for the immersive, lifelike, three-dimensional effect.

Listening impressions
Fleetwood Mac’s The Chain demonstrated crisp, expressive guitar notes and a warm opening kick drum. The chorus bassline gave the track depth, while the solo bass passage in the instrumental bridge made a particularly strong impression.
For high notes and falsetto, the reviewer chose Cradled in Love by Poets of the Fall. Marko Saaresto’s singing remained comfortable rather than piercing in the verses and chorus, with smooth transitions between lower and higher pitches.
Heavier material was equally convincing. On System of a Down’s Holy Mountains, the speaker handled Serj Tankian’s shift from gentle singing to forceful belting seamlessly. In 070 Shake’s Elephant, strong bass accompanied vocals whose deliberately scratchy, distorted character remained clearly audible.
Quieter selections revealed detail as well. In Lumiére from Clair Obscur: Expedition 33, the reviewer praised Alice Duport-Percier’s vocals and the delicate but well-defined acoustic guitar. Main Theme Pt. 3 from Baldur’s Gate 3 made it easy to appreciate the interplay of flute, oboe, French horn and the other instruments.
Verdict

For listeners wanting high-quality Wi-Fi playback alongside a voice assistant, the reviewer strongly recommended the Denon Home 350. Its six drivers, including two large woofers, produced detailed, immersive sound capable of filling most rooms.
Touch, app and voice control provide several convenient ways to operate it. Strong HEOS synchronization also makes it useful in multi-room systems or as a left or right stereo channel. The high price remains the chief reservation, but the reviewer considered its sound exceptional and described it as a new favorite for enjoying playlists.
