- Surround yourself in the story: Go deeper into every scene with spatial audio. Dolby Atmos and the upward-firing drivers work in concert to immerse you in a multidimensional soundstage. Youll hear planes as if theyre flying overhead, sense footsteps moving across the room, and feel the music swell all around you.
- Feel the bass: Experience every rumble, roar, and beat you've been missing with clean, pulse-pounding bass. Sub 4 takes over the lowest frequencies so paired speakers are free to focus on midrange and high frequencies so everything sounds even clearer.
- Wonderfully wireless: Place Sub 4 anywhere in the room. It connects to the soundbar over WiFi, so you can create the setup that works best for your space.
- Perfectly tuned for the room: Using the microphones in your iOS device, Trueplay tuning technology analyzes the unique acoustics of your space and optimizes the EQ. So all your content sounds just the way it should.
- Breeze through setup: Simply plug in the power cable, connect your phone or tablet to WiFi, and open the Sonos app. It will guide you through connecting the soundbar to your TV and syncing your TV remote for streamlined control.

If you're looking to add wireless speakers, etc. to your TV or other entertainment devices, Sonos is the way to go. Sonos is quite expensive, but you're buying not only high-quality audio devices but also the flexibility of being wireless for sound and the interconnectedness of all the Sonos devices. The Sonos app recognizes all of your various devices and makes it easy for them to work together. You can assign devices to specific rooms or, if you want, set up a home audio network where music is played everywhere. The Sonos app also integrates access to Apple Music, Amazon Music, or just the Sonos music that they offer. For a home theater, starting with a Sonos soundbar opens the door for adding other Sonos speakers and a Sonos subwoofer. The sound bar, while using the Sonos application on your smartphone, will recognize other speakers and a subwoofer in the room. You also can configure the speakers to work separately, or they can be part of a surround sound system tied to the Sonos sound bar. The nice thing about each of the system audio components is that individually, you can touch the component (a speaker or soundbar for example) and control the room sound level, so you don't always have to go to the Sonos app on your smartphone to do so. You can get great sound for your entertainment system without requiring a receiver and complicated wiring. Generally, you just need: • A power cable • An HDMI cable for connecting to a TV • Preferably an Ethernet cable so all the devices can work over your Wi-Fi network • The Sonos subwoofer can work wirelessly, without requiring an Ethernet cable connection which is optional

I’ve owned a lot of soundbars over the years, but the Sonos Ultra is on another level. The moment I set it up (which took less than 10 minutes thanks to the simple HDMI eARC connection and the Sonos app’s step-by-step guidance), I knew this was something special. The 9.1.4 spatial audio with Dolby Atmos is simply jaw-dropping—sound doesn’t just come from the front, it feels like it’s coming from everywhere. Movies completely fill the room with action, and the Sound Motion technology places effects so precisely that you feel like you’re right in the middle of the scene. Dialogue is crystal clear thanks to the AI-powered Speech Enhancement—no more rewinding because I missed what someone said. Music is equally impressive, with rich detail, deep bass, and a soundstage that feels like a live performance. The elegant design blends beautifully with my living room—it looks high-end but doesn’t distract from the screen. Control is effortless too: I can use my TV remote, the Sonos app, or even just my voice with Alexa. Trueplay tuning made a noticeable difference, automatically adjusting the sound to my room’s acoustics. Streaming is seamless with WiFi, Bluetooth, AirPlay 2, and Spotify Connect—I’ve played music from every source without a hiccup. I eventually paired it with a Sonos Sub and Era 300 rears, and the surround experience is honestly better than some theaters. Plus, I love being able to expand to other rooms with Sonos speakers for whole-home audio. If you’re serious about home entertainment, this is the best soundbar you can buy. The Sonos Ultra is pure audio magic.

The Sonos Arc Ultra delivers an impressive cinematic experience. The soundstage is wide and well-defined, making both Dolby Atmos movies and regular TV in 5.1 sound rich and immersive. While the height channels are subtle, the difference is noticeable when disabled, and the overall surround effect feels like sound is coming from all around. For music playback, the Arc Ultra alone doesn’t shine quite as brightly, but paired with Era 300 speakers it becomes outstanding. Despite the marketing around the bass driver, it’s solid rather than overwhelming — enough to fill a room, but not “knock your socks off.” Design-wise, the Arc Ultra is sleek, substantial, and beautifully built. Its size adds presence, and it feels premium in hand with no flexing. In fact, it looks so good it makes the rest of the room feel like it needs an upgrade. Setup was flawless. Straightforward and simple. At its premium price, it’s a serious step up from the Beam and probably worth it, though I sometimes wonder how it compares to the standard Arc, now much cheaper. Still, for anyone who values immersive home theater sound in a stylish package, the Arc Ultra is highly recommended.

I purchased this SONOS SOUNDBAR because I literally was having problems understanding the voices through my Samsung NEO TV speakers and had to increase the NEO volume to about 85% to get any common audio. Installed the power cable for the SONOS and then connected the HDMI cable into the HDMI E ARC input, then downloaded the SONOS app to control the soundbar volume and features. Instant clear vocals and more than enough volume power through the expanded SONOS soundbar speakers. What could be easier? It is pricey, but worth every dollar. Highly recommend.

The Sonos Arc Ultra delivers an impressive, room-filling audio experience that instantly elevates movies, sports, and gaming. Dolby Atmos performance is excellent—clear dialogue, powerful bass, and immersive surround effects without needing a full speaker setup. The sleek, modern design also blends seamlessly into any living room. Setup through the Sonos app is straightforward, and integration with other Sonos products is a major plus for anyone building a multi-room system. Voice control and reliable connectivity make day-to-day use smooth and convenient. The only drawbacks are the premium price and the fact that optimal performance really benefits from adding a subwoofer or surrounds, which increases the overall cost. Even so, the Arc Ultra stands out as one of the best soundbars in its class
