There's even built-in voice assistant support to enjoy hands-free control right from the comfort of your couch. Plus, compared to the Sonos Arc with Sub + One SL Speakers, the Era 300 offer additional up-firing drivers for a more immersive overall sound.

The Sonos Ultimate Immersive Set with Arc is great for music. This premium soundbar has a room correction tool, so iOS users can optimize the bar's sound based on their room's unique acoustics. That said, anyone can manually adjust the bar's sound with bass and treble adjustments, which is handy. The resulting sound is clear and balanced, with enough rumble in the sub to bring bass-heavy genres to life.
The Sonos Ultimate Immersive Set with Arc is great for movies. The bar supports many audio formats commonly found on streaming platforms and Blu-rays, including Dolby Digital and Dolby Atmos.

The Sonos Ultimate Immersive Set with Arc comes in two colors: 'Black' and 'White'. We tested the 'Black model with the following sub and speaker labels, but the soundbar itself doesn't have a label. This setup is made from a Sonos Arc that's paired with two Sonos Era 300 speakers and a Sonos sub. It can be purchased as a bundle, but the Sonos Arc is also available as a standalone bar. You can purchase the wireless subwoofer separately as well as the Sonos Era 300 if you're looking for a standalone speaker too. All of these products come in Black or White variants

The Sonos Ultimate Immersive Set with Arc is a really premium, high-end soundbar setup that's versatile enough for lots of different audio content. It adds Sonos Era 300 speakers to the Sonos Arc for a more immersive, all-around sound. Up-firing speakers on the satellites give a clearer and more realistic feel to height content like Dolby Atmos, too. That said, it doesn't have as many features as other premium setups, so, for example, you can't use the bar for video passthrough. If you don't need these features and are already a fan of Sonos products, it's worth a look.

The Sonos Ultimate Immersive Set with Arc and the Samsung HW-Q990C are both very premium soundbar setups with versatile performances, but the Samsung is a touch better overall. The Samsung has more features like Bluetooth support, a graphic EQ, and HDMI In ports for video passthrough. While the Sonos has a wider soundstage, it also sounds a bit over-processed at times, especially compared to the Samsung. If you already own products in Sonos's ecosystem, you may find it's a better buy.
The Sonos Ultimate Immersive Set with Arc is better than the Sonos Arc with Sub + One SL Speakers. Both setups take the Sonos Arc paired with a Sonos Sub but use different satellite speakers. The Ultimate Immersive Set uses the Sonos Era 300 speakers, with up-firing drivers built in for a more immersive sound, especially with surround sound and height content. You get a more clear and real feel with sound effects as a result.
The Sonos Ultimate Immersive Set with Arc and the Bose Smart Soundbar 900 with Speakers + Bass Module are both very premium setups with versatile overall performances. Depending on your listening habits, you may prefer one over the other. The Sonos supports more audio formats, such as DTS, and the up-firing drivers on its satellites provide a more immersive sound with Atmos content. However, it doesn't support Bluetooth like the Bose. The Bose's stereo soundstage is better, too.
The Sonos Ultimate Immersive Set with Arc is better than the Sony HT-A7000 with Speakers + Bass Module. They're both very premium setups, but the Sonos has a better sound. It gets louder and offers a more even frequency response, so sound effects are clearer and more present in the mix. Plus, the up-firing channels on its satellites give a more clear and real feel to height content like Atmos. The Sony does have Bluetooth support, though, unlike the Sonos, as well as HDMI In ports for video passthrough.
The Sonos Arc is a premium soundbar with a sleek design. It's a solid and heavy soundbar with a sturdy build, and it's available in 'Black' and 'White' color variants.
The Sonos Sub is a large subwoofer with a glossy finish. It has a unique design, with two subwoofers facing each other on the inside, and each of their ports facing out into the rectangular hole in the middle.
The Sonos Era 300 speakers are available as standalone speakers, but you can also pair them to the bar for surround sound. They're rounded speakers with a sleek and stylish design, and the grilles in front help to protect the drivers inside.
The bar is pretty wide, so it doesn't fit between the legs of a 55" TV stand. Still, it won't obscure the screen since it isn't very tall.
The sub is large and heavy but about the same size as a typical desktop computer. It connects wirelessly to the bar, too.
The Sonos Era 300 is a bigger, wider speaker compared to the Sonos One SL speakers. It takes up some space in your living room, but since it connects to the bar wirelessly, you have some flexibility when setting it up.
You can mount the bar and the satellites to your wall. However, you have to purchase the brackets from Sonos separately.
The Sonos Ultimate Immersive Set with Arc has an excellent build quality. Overall, it's a premium setup that feels sturdy and solid. The bar and the speakers are both made mostly of plastic, which feels very durable. Each have grilles designed to protect the drivers inside. Plus, the plastic build for the subwoofer feels very strong and solid.
The Sonos Ultimate Immersive Set with Arc has a great stereo frequency response. This premium soundbar has a room correction tool available only with iOS devices. However, Android users can always use its bass and treble adjustments to compensate for room acoustics changes. Overall, you get a nice and balanced sound suitable for listening to many different types of audio content. The addition of the Era 300 speakers means that stereo content like music plays from all available channels on the bar as well as the satellites. As a result, you notice that audio sometimes sounds over-processed, especially compared to other premium setups like the Samsung HW-Q990C. It's not too distracting, so the sound remains pleasing overall.
We also evaluated the bar's performance when listening to Dolby Atmos Music. It provided a nice listening experience, especially with tracks like "On The Run" by Pink Floyd, since sound is accurately placed in the space around you for an immersive overall feel. With "Bad Guy" by Billie Eilish, the thumpy bass makes her vocals subtle in the mix, but it's not enough to overpower her voice. You get an all-around sound, which sometimes seems a bit fake, but it's not overwhelming enough to take away from the overall listening experience.
The default settings for this soundbar fall without our target range, so if you prefer a more even sound with stereo content, we recommend sticking to them.
The Sonos Ultimate Immersive Set with Arc has a great stereo soundstage. The soundstage itself is perceived to be a bit wider than the bar. It tries to use some tricks to make the soundstage seem wider than that, which means that sound effects can seem like they're pushed towards the far ends at times rather than coming from a more natural location in the soundstage. Still, focus is good overall, so you can pinpoint effects to accurate locations in the space around you.
This soundbar gets loud, so it can fill up larger and more open spaces with sound. There's not a lot of distortion when you push it to max volume, either, so audio is reproduced with clarity even when you crank up the volume.
Distortion falls within good limits at a normal listening volume, so audio reproduction is clean and pure. As with most bars, there's a jump in distortion at max volume, but it's still within decent limits, so you don't notice it.
The Sonos Ultimate Immersive Set with Arc has a discrete center channel designed to improve vocal clarity in the mix. This channel's balanced frequency response means that dialogue is clear and present in the mix, and it's easy to follow along with the action on screen.
The Sonos Ultimate Immersive Set with Arc has an excellent surrounds performance. Due to the number of drivers built into the Sonos Era 300 speakers, the 5.1.2 bar transforms into a 7.1.4 setup with two extra surround channels. Pulling the satellites away from the wall also ensures the side-firing drivers have enough space to distribute sound. As a result, you get a really clear and real feel to your audio, and sound effects stretch into the space around you as if you've been dropped right into the heart of your movies. The frequency response on these surround channels is quite balanced, too, so effects reproduce with clarity and detail.
The Sonos Ultimate Immersive Set with Arc uses up-firing speakers on both the bar and the satellites to ricochet sound off the ceiling, which creates the illusion of height with Dolby Atmos content. The frequency response on these channels is very even and balanced, meaning that sound effects are clear and accurate in their reproduction, so you don't miss any of the action taking place around you.
For a better sense of the bar's real-world performance, we also subjectively evaluate its soundstage with height content. This setup provides a really good, immersive sound. Sound effects stretch into the space around your couch, giving you a clear and real feel. The sub brings out the rumble in action-packed scenes, too. Plus, compared to the Sonos Arc with Sub + One SL Speakers, the Sonos Era 300 speakers add two extra up-firing drivers to the mix, which adds a bit more height over your head. It's especially noticeable in scenes where a helicopter flies over your head. It's a premium setup that stands out from the crowd.
The Sonos Ultimate Immersive Set with Arc has many sound enhancement features. As with most premium setups on the market, it has a room correction tool to optimize the bar's sound based on your room's unique acoustics. It's only available with iOS devices at this time, though. There are some bass and treble adjustments on hand for manual adjustment, though, which is handy for Android users. Compared to the Sonos Arc with Sub + One SL Speakers, the Sonos Era 300 speakers offer additional features, including a tool that sets the speakers to add either an Ambient or Full surround sound. However, this doesn't apply to Dolby Atmos Music.
You can connect the bar to your TV over HDMI or Optical. Without an HDMI In port, though, the bar doesn't support video passthrough.
The Sonos Ultimate Immersive Set with Arc supports many common audio formats over HDMI ARC. It can playback common 5.1 surround sound formats like Dolby Digital and lossless and object-based formats like Dolby Atmos. You're likely to come across both on streaming platforms and Blu-rays.
Common surround sound formats like Dolby Digital and DTS are supported via Optical. Dolby Digital is the more common of the two, but DTS is often used as a fallback for higher-quality formats on Blu-rays.
The Sonos Ultimate Immersive Set with Arc has an amazing latency performance. Latency is low, meaning the audio you hear is in sync with the video you see on the screen. It's especially great for watching videos and movies. Some apps and TV may compensate for latency differently, though.
Without an HDMI In port, this bar can't do video passthrough.
As with most Sonos soundbars, the wireless connectivity options are limited. You can stream audio from your mobile devices over Wi-Fi, Apple AirPlay 2, and Spotify Connect. There's no Bluetooth support, though.
While the bar lacks a display, two lights on top of the bar change colors depending on the registered commands. A microphone light also shows when the microphone is activated.
A few controls are on top of the bar to control basic functions like play/pause, the volume, and the microphone.
Sonos soundbars don't come with remotes; you're meant to control them through the S2 app. The app lets you connect multiple Sonos products to spread audio throughout your room and control the sound features on the bar itself. You can see a video here.
The Sonos Ultimate Immersive Set with Arc has built-in voice assistant support that you can mute using the included button. If you're streaming with Apple AirPlay 2, you can also set up Siri to control Apple Music.
