Detailed Feature Comparison
Microphone and Voice Assistant Integration
Sonos Arc: The Sonos Arc features far-field microphones that support voice interaction via Amazon Alexa or Google Assistant. This makes it a practical choice for smart homes, where hands-free operation is key. You can adjust volume, control playback, ask for weather updates, or manage other connected devices with your voice. While convenient, always-on mics have sparked privacy concerns for some users. Regardless, if you’re looking for built-in voice control without an extra device, the Arc offers full functionality natively.
Sonos Arc SL: The “SL” in Arc SL stands for “speechless,” and that’s exactly what defines this version: no built-in microphones. As a result, the Arc SL cannot natively use Google Assistant or Alexa—although it can still be controlled via the Sonos app or other mic-enabled Sonos speakers. This variant is tailored for privacy-conscious buyers or households that already have voice assistants in other devices (like an Echo Dot). It’s important to note that the absence of mics does not impact sound quality or performance.
Design and Aesthetics
Sonos Arc: The Arc carries the standard black Sonos design language, with a slightly glossy finish and visible Sonos branding. Built for placement under large TVs, it integrates well with most contemporary living room aesthetics. The perforated grille wrap gives it a modern and high-end feel. For buyers seeking consistency with other Sonos components or modern furniture, the Arc’s appearance is in line with the brand’s signature look. However, it may stand out more than its SL equivalent due to its branding and finish.
Sonos Arc SL: The Arc SL offers a darker “Shadow Edition” colorway with a more subtle logo, making it visually stealthier in darker or more minimalistic rooms. While physical dimensions and materials remain consistent with the standard Arc, the muted finish may appeal to users who prefer tech gear to blend into the background. This makes the Arc SL a better visual fit in sleek or home theater-centric environments, particularly when paired with blacked-out TVs or AV racks.
Smart Home Compatibility
Sonos Arc: With native voice assistant integration, the Arc acts as both a soundbar and a smart speaker hub. Users can directly operate smart lights, thermostats, or media through built-in voice commands. This makes it a compelling single-device solution for those built into either Amazon or Google ecosystems. If seamless IoT and voice control is a priority, Arc enhances daily usage by removing the need for multiple devices or apps to control smart features.
Sonos Arc SL: While it doesn’t include a microphone, the SL can still participate in a smart home setup when combined with another voice-enabled Sonos speaker. Via the app or partner devices, users retain indirect control over smart functionality, but not through the soundbar itself. This setup may require some additional networking or layering if full integration is desired. That said, many users who already use smart assistants on their phones or through smart hubs won’t be restricted.
Included Accessories and Connectivity
Sonos Arc: The Arc typically includes an HDMI eARC cable, power cable, and an optical audio adapter, making it easier to set up with a wider range of TV models including those lacking eARC ports. This added flexibility in port options eases installation challenges and supports more TV brands out-of-the-box. Lack of Bluetooth remains a downside for some wireless users, but HDMI and Wi-Fi remain the core connection paths for optimal lossless audio.
Sonos Arc SL: Reports indicate that some models of the Arc SL may not include the optical audio adapter in the box, which could complicate setup for users with older TVs. Functionally, the SL shares the same HDMI eARC port and wired/wireless network capabilities, so performance isn’t limited—just potential convenience. Prospective buyers should verify what’s included in their region, especially if they rely on optical inputs. The omission reflects a slight cost-trimmed packaging approach.
Price and Value Consideration
Sonos Arc: As the full-featured variant, the Arc typically sits at a higher price point—about $150 more than the Arc SL—due to its built-in voice assistant functionality. For some users, this addition more than justifies the extra investment, particularly if it’s the centerpiece of a voice-controlled home. However, if voice control is unused, that premium may feel unnecessary in a tightly budgeted setup.
Sonos Arc SL: Offered at a more affordable price point, the Arc SL delivers the same premium audio performance minus the integrated mics. This makes it one of the better values in the premium Dolby Atmos soundbar market for non-voice assistant users, especially when paired with a Sonos Sub or surround speakers. Budget-conscious buyers willing to sacrifice smart integration for savings often prefer the Arc SL.
Sonos Arc vs Arc SL, Customer Review Analysis
Sonos Arc
Customer feedback for the Sonos Arc is largely positive, with high praise for its immersive Dolby Atmos support and seamless integration with the broader Sonos ecosystem. Many users love how the Arc dramatically improves TV audio, especially in open-concept or large living rooms. Reviewers frequently mention its sleek design and voice assistant integration as standout features. On Amazon and Best Buy, long-term owners commend the build quality and consistent firmware updates. However, some users report issues with eARC compatibility on older TVs, and a few note connectivity drops during HDMI-CEC commands. A consistent critique is the premium pricing and the lack of HDMI passthrough. That said, reliability over time appears strong with few major durability issues reported after extended use.
Sonos Arc SL
The Sonos Arc SL is appreciated by those who value privacy and don’t mind the absence of built-in microphones. Customers who purchased it from outlets like Costco often cite its value-driven pricing and minimalistic appeal. User reviews highlight identical audio performance compared to the standard Arc, making it a favorite among home theater enthusiasts who already use external voice assistants or prefer not to use them at all. Despite the overall satisfaction, some buyers express disappointment at the lack of communication about the missing voice control—especially if they bought it without understanding the “SL” stands for “speechless.” The Arc SL’s long-term performance is reported as stable, mirroring the Arc in firmware support and reliability. Still, buyers should note that the SL is sometimes harder to find since it’s retail-limited or bundled in select packages.
| Common Praise | Common Complaints | |
|---|---|---|
| Sonos Arc | Immersive sound, Dolby Atmos support, smart assistant integration, solid build quality | High price, HDMI-eARC issues on older TVs, no HDMI passthrough |
| Sonos Arc SL | Same audio as Arc, good value for privacy-focused users, clean design | No voice assistant, less widely available, lack of clear product labeling |
