Compare Sonos Arc Soundbar vs Samsung HW-Q990D Soundbar

Trueplay room calibration was praised for improving or tailoring sound, but its Apple-only limitation frustrated Android users.

SpaceFit/room calibration is widely present and sometimes useful, though a few reviewers found its effect subtle or hard to hear.

AirPlay was viewed positively as a handy wireless music option, especially for Apple users.

AirPlay support is consistently listed among the wireless streaming options.

Reviewers cite the system's high total amplification, supporting its large-room home-theater ambitions.

App reliability and usability were mixed: some found Sonos polished and easy to navigate, while others disliked the layout or had reconnection trouble.

SmartThings is generally described as easier than the remote and useful for setup and sound adjustments.

Audio format support was mixed: Dolby Atmos support impressed reviewers, but DTS:X, hi-res, and TV passthrough limitations were repeated caveats.

Format support is a clear strength, with Dolby Atmos, DTS:X and other surround formats repeatedly confirmed.

Backwards compatibility was a drawback because some older Sonos devices are not compatible with the S2-based Arc setup.

Legacy and non-Samsung compatibility is supported mainly through HDMI, optical, and use with non-Samsung TVs, though Samsung TVs unlock extras.

Bluetooth-related feedback was negative because reviewers complained about the original Arc’s lack of conventional Bluetooth support.

Bluetooth works for streaming, but reviewers focus more on support than detailed stability testing.

The cabinet and physical construction are described as solid, metal-heavy, durable, and premium.

Chromecast support is broadly cited, but one reviewer notes it is not supported in the US.

Cohesive presentation was mixed: standalone home-cinema cohesion impressed some reviewers, while one found music less authentically cohesive than stereo speakers.

The system is repeatedly praised for cohesive handoffs between bar, surrounds, and subwoofer.

The top-panel buttons are basic but clicky and preferred over touch-sensitive controls.

Design and aesthetics were praised for a classy, unobtrusive, blend-in look, though the Arc’s size still requires space.

The design is understated and sleek, though large and visually similar to prior models.

Build quality impressions were mixed: one reviewer praised the form-function blend, while another complained that the plastic body attracts dust.

Build quality is considered premium and sturdy, with a few size-related caveats.

Detail retrieval was widely praised, with reviewers highlighting separation, crispness, clarity, and fine detail in music and movies.

Detail retrieval is strong, with reviewers hearing fine effects, instrument separation, and crisp textures.

Dialogue clarity was usually strong and helped by Speech Enhancement, though one direct comparison placed it behind some rivals for immediate clarity.

Dialogue clarity is a consistent highlight across movies, TV, and sports.

High-volume composure was generally praised, with distortion described as limited to pushed bass and volume settings or absent in stress-free loud playback.

High-volume behavior is mostly clean, but a few reviews mention subwoofer crackle, chuffing, or muddy bass.

Dolby Atmos height effects were among the Arc’s strongest attributes, with reviewers praising overhead realism, height presence, and immersive Atmos delivery.

Dolby Atmos is the strongest consensus feature, with convincing height, overhead effects, and immersive placement.

Dynamic headroom was strong overall, with reviewers praising power, subtlety, and big dynamic shifts, though one found the Arc less quick than some rivals.

Dynamic range and cinematic impact are strong, especially with action scenes and big effects.

EQ controls were viewed as useful for bass, treble, and loudness adjustments, though not a replacement for every hardware limitation.

EQ, tone, woofer, channel-level, voice, bass, and sound-mode controls give broad customization.

The Arc was widely described as balanced, smooth, and controlled, though a few reviews wanted more low-end weight from the standalone bar.

Most reviewers describe a balanced, clear sound, though some note bass-heavy or muddy moments.

Gaming HDMI passthrough was a weakness because the single HDMI connection and lack of passthrough can complicate consoles and streaming boxes.

HDMI passthrough is a major upgrade, especially for 4K/120Hz gaming and consoles.

Google Assistant support received a positive hands-on assessment when used as the Arc’s selected assistant.

Google-related support appears through Google Home, Google Assistant, or Chromecast, with regional caveats.

HDMI 2.1 gaming is a standout addition, adding 4K/120Hz, VRR, ALLM, and low-latency use cases.

HDMI ARC/eARC was valued for getting the best surround experience, but reviewers warned that TV passthrough support can complicate Atmos setup.

HDMI ARC/eARC support is consistently confirmed as the preferred wired TV connection.

Home theater integration was a major strength, especially the ability to expand with Sonos surrounds, Sub, and multi-room setups.

Home-theater integration is strong, especially with Samsung TVs via Q-Symphony and menu integration.

Inter-speaker connectivity was praised as easy and impactful when adding or connecting Sonos components.

Most reviewers report easy or reliable inter-speaker connectivity, though one user found a defective HDMI input.

Lip-sync risk was raised as a potential downside when a TV lacks proper passthrough support.

Latency is generally controlled, with reviewers reporting low input lag or synced audio/video.

Reviewers consistently described the Arc as loud, powerful, and room-filling, with enough scale for larger spaces and home theater use.

Maximum volume and room-filling power are strong enough for large or open spaces.

Low-volume features were praised for improving late-night listening by reducing bass, stabilizing output, and keeping dialogue clearer.

Low-volume tools like Night Mode, Private Listening, and voice emphasis help late-night or quieter listening.

The Arc’s microphone hardware was positively described through its far-field mic array for voice pickup.

Microphones support SpaceFit, voice features, and mic-off controls, though they are not a major review focus.

Sonos multi-speaker pairing was praised as reliable and easy, especially for users building or expanding a whole-home Sonos system.

The sub and rear speakers usually pair automatically and reliably.

Omnidirectional-style immersion was praised in one review that described sound arriving from every direction.

Reviewers describe room-filling, all-around sound that creates a dome or surround bubble.

On-device controls are present and useful when the remote is unavailable.

Optical support was treated as a fallback with a major tradeoff because it limits Dolby Atmos usefulness.

Optical/Toslink input is consistently available, though usually secondary to HDMI eARC.

Privacy discussion centers on the microphone mute control and mic-off indicator rather than broader data practices.

Rear-speaker power cables are usable and sometimes praised, but some reviewers still wanted longer cables.

Remote usability was mixed-positive: existing TV remotes usually work well, but some reviewers disliked the lack of a dedicated physical remote.

The remote is usable, but the tiny display and limited shortcuts make deeper adjustments less convenient.

Setup simplicity was a clear strength, with reviewers repeatedly calling installation quick, guided, and easy.

Setup is consistently described as simple, intuitive, or nearly effortless for a multi-piece system.

Alexa and smart assistant integration was praised for convenient hands-free control of volume, playback, and smart-home devices.

Smart assistant integration is strong, with Alexa repeatedly cited and some reviews also mentioning Google Assistant or Bixby.

Smart features were a strength, with reviewers praising Sonos smarts, streaming breadth, and the app as a central media hub.

Smart features are extensive, including SmartThings, Q-Symphony, wireless Atmos, Tap Sound, and smart-home functions.

Soundstage height was praised for convincing vertical presence and sounds that moved above the listener.

Soundstage height is usually impressive, though one reviewer wanted more overhead sensation.

Spotify voice playback was described as working beautifully with the Arc’s voice assistant setup.

Spotify Connect is supported, but one reviewer reports a frustrating volume-step issue.

Status indicators were praised for being subtle and not overly bright.

Status indicators are a recurring weakness because the front display is small and hard to read.

Stereo imaging was mixed: reviewers praised width and speaker-like imaging with surrounds, but some found music less direct or less precise than stereo speakers.

Stereo imaging is better than many soundbars, especially with modes that widen or repurpose rear speakers.

Opinions on the Sub were context-dependent: several reviewers said the Arc works well alone, but bass-focused listeners and movie fans benefit noticeably from adding a Sub.

The subwoofer is generally powerful, controlled, and well integrated, with a few bass caveats.

Surround simulation was a major strength, with reviewers praising the Arc’s virtual 3D field, room-filling movie sound, and immersive presentation while noting it is not true in-ceiling Atmos.

Surround performance is a major strength, with convincing side, rear, and front-to-back movement.

Value opinions were mixed: many reviewers called the Arc worth it or excellent value, while others stressed the premium price and extra cost of a full system.

Value is context-dependent: reviewers like the complete package, but cheaper Q990C deals undercut it.

Video passthrough support was a consistent weakness because reviewers criticized the absence of HDMI input/passthrough.

Video passthrough is strong, including 4K/120Hz gaming and HDR format passthrough.

Voice assistant responsiveness was rated highly, with reviewers saying assistants worked well and commands were picked up even during loud playback.

Vocal clarity in music and general playback drew strong praise, with reviewers calling vocals and higher frequencies very impressive.

Voice clarity is strong, helped by center-channel strength and optional voice enhancement.

Voice recognition was praised for continuing to work while content was playing.

Despite its size, the Arc was described as easy to move and reposition.

The system is large and heavy enough to require planning, even though that heft supports a premium impression.

Wi-Fi reliability was mixed, with one reviewer reporting app reconnection struggles and another finding the Wi-Fi-based system more reliable than competing soundbars.

Wi-Fi and wireless TV connections work well for some reviewers, but HDMI remains the safer recommendation.

Wired input flexibility was criticized because the Arc’s physical connection options are limited.

Wired inputs are strong, centered on HDMI/eARC with optical as a backup.
