Compare Sonos Arc Soundbar vs Ultimea Nova S50 Soundbar

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

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

One reviewer gave a rough power note for the subwoofer, but also framed it as something awaiting manufacturer confirmation.

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

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

Review evidence consistently shows Dolby Atmos compatibility/decoding plus HDMI eARC and Bluetooth, though one reviewer stressed that decoding does not mean true Atmos output.

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

The 3.5mm input helped with an older TV, giving the soundbar useful backward compatibility beyond HDMI.

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

Bluetooth is available and one reviewer described Bluetooth 5.3 as fast, but long-range or long-term stability was not deeply tested.

The manufacturer review cites a honeycomb diaphragm structure as part of the cabinet/driver design.

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

Overall presentation is context-dependent: TV and movie playback can sound cohesive, while music and heavy bass can upset clarity.

Button feel is generally positive, with tactile remote buttons and a complete button layout noted.

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

The compact design is a major strength, though reviewers split between sleek/small praise and cheap-looking criticism.

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

Build quality is mixed: one review called out cheap plastic, while others cited a metal grille, sleek finish, or advanced construction.

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

Detail retrieval is limited, with one review specifically saying treble nuance was lost during music playback.

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 mixed: it can be clear in some scenes, but bass-heavy presets can make voices muffled.

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

Distortion performance is split, with one reviewer hearing peaks and pinches while others found the sound stayed clean at high volume.

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

Atmos height effects are the biggest tradeoff: reviewers heard some virtual immersion, but also emphasized the lack of true upfiring height output.

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 headroom is mixed: one review heard clipping and peaks, while another found the bar stayed composed at maximum volume.

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

EQ customization is useful but basic, built around Movie, Game, Music, and bass adjustment, with Movie usually favored.

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

Frequency balance is the weak point, with repeated evidence of bass excess, treble pinch, and music sounding less natural.

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

Gaming HDMI passthrough is effectively absent because the unit has no HDMI output for passthrough.

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

HDMI 2.1 is mentioned positively, but the evidence does not show broader gaming passthrough features.

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 is a practical strength, with auto-boot, auto-switching, and TV control behavior described across reviews.

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

Reviewers generally frame it as a strong TV-speaker upgrade rather than a serious home theater replacement.

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

The subwoofer connection is simple but wired, creating a tradeoff between easy hookup and cable clutter.

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

Lighting is limited to functional LED indicators rather than decorative lighting effects.

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

Reviewers repeatedly found the Nova S50 surprisingly loud for its size, including small-room and maximum-volume praise.

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

Low-volume performance is limited by high frequencies that can pinch even at low listening levels.

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

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

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

Virtual 360-degree sound decoding gives some directional effect, but it is not true omnidirectional speaker coverage.

On-device controls cover key basics such as volume, power, source selection, and Bluetooth.

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

Optical support is repeatedly listed and demonstrated as one of the available wired inputs.

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 mostly praised for tactile or ergonomic controls, although one review found the play/pause function ineffective for TV.

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

Setup simplicity is one of the clearest strengths, with multiple reviewers describing very quick HDMI/power setup.

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

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

Smart features are minimal because one review explicitly notes there is no smart connectivity.

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

Soundstage height is partially simulated, but reviewers also stress the absence of physical upfiring speakers.

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

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

Status indicators are practical, with LED feedback for volume, inputs, and operating modes.

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/directionality is supported by one review describing movement and sound from different directions during a sound test.

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 produces more bass than expected and has adjustable levels, but can become too much or peak depending on content.

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 simulation is a relative strength for the price, with reviewers describing voices around them, atmospheric 3D sound, and more engaging audio.

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 consistently strong, especially as a cheap upgrade from TV speakers and a hard-to-beat under-$130 package.

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

Video passthrough support is weak because the soundbar lacks HDMI output.

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 acceptable for basic TV use, with centered speech and audible interviews, but not consistently refined.

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.

Weight convenience is excellent thanks to the tiny, lightweight bar.

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.

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

Wired input coverage is broad for the class, including HDMI/eARC, optical, aux/3.5mm, and USB references.
