Detailed Feature Comparison
Microphone, Voice Assistant, and Smart Home Integration
Sonos Arc: The Sonos Arc features built-in far-field microphones for hands-free voice control through supported assistants, including Amazon Alexa and Google Assistant. Users can adjust volume, control music playback, and manage compatible smart home devices such as lights and thermostats. This makes it a convenient choice for households that rely on voice commands. The microphones can also be disabled when not needed, although privacy-conscious buyers may prefer a soundbar without microphones entirely.
Sonos Arc SL: The Arc SL removes the built-in microphones, making it a better fit for users who prioritize privacy or don’t need hands-free controls. It can still be operated through the Sonos app or controlled using a compatible external voice-enabled device. Importantly, removing the microphones does not affect Dolby Atmos performance, sound quality, or core streaming features.
Which should you choose? Choose the Sonos Arc if built-in voice control is important to your smart home setup. Choose the Arc SL if you prefer a microphone-free soundbar without sacrificing audio 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.
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: TV Compatibility and Dolby Atmos
The Sonos Arc and Arc SL offer identical TV connectivity and Dolby Atmos support. Both use HDMI ARC or eARC for TV audio, while older TVs can connect through an optical adapter. The main difference is the audio quality and formats each connection supports.
HDMI ARC vs eARC vs Optical
| Connection | Audio Support | Key Limitation |
|---|---|---|
| HDMI ARC | Dolby Digital Plus, Dolby Atmos (compressed) | No lossless Dolby TrueHD |
| HDMI eARC | Dolby Atmos, Dolby TrueHD, multichannel PCM | Requires a compatible TV |
| Optical | Stereo PCM, Dolby Digital 5.1 | No Dolby Atmos or HDMI-CEC |
For streaming services such as Netflix and Disney+, HDMI ARC is generally sufficient for Dolby Atmos when supported by the TV. HDMI eARC is preferable for lossless audio from compatible Blu-ray players and gaming consoles.
Gaming Consoles and Streaming Devices
Neither soundbar has an HDMI passthrough input. Connect your PS5, Xbox Series X, or streaming device directly to the TV, then connect the TV to the Sonos soundbar through HDMI ARC/eARC.
This setup preserves supported TV gaming features such as 4K/120Hz, VRR, and HDR while allowing compatible surround sound formats.
Which Connection Should You Use?
- HDMI eARC: Best for gaming, Blu-ray, and lossless audio.
- HDMI ARC: Suitable for most Dolby Atmos streaming.
- Optical: A fallback for older TVs without HDMI ARC.
Bottom Line: In the Sonos Arc vs Arc SL comparison, neither model has an advantage in TV compatibility. Choose HDMI eARC whenever available for the broadest audio-format support.
Sonos Arc vs Arc SL: Privacy and Voice Control
The main difference between the Sonos Arc and Arc SL is the built-in microphone. The Arc features a four-microphone array for hands-free voice control, while the Arc SL has no microphones, making it a better choice for privacy-conscious buyers.
The Sonos Arc allows users to disable its microphones using a dedicated button. However, disabling them is not the same as owning an Arc SL, which has no microphone hardware.
The Arc SL can still be controlled through another compatible voice-enabled Sonos speaker. Both models retain identical audio performance, Dolby Atmos, AirPlay 2, HDMI eARC, music streaming, and Trueplay tuning.
Privacy and Voice Control Comparison
| Feature | Sonos Arc | Sonos Arc SL |
|---|---|---|
| Built-in microphones | Yes, four | None |
| Microphone control | Can be disabled | Not applicable |
| Direct voice assistant | Supported | Not supported |
| Voice control via another Sonos speaker | Yes | Yes |
| Dolby Atmos and streaming | Identical | Identical |
| Trueplay tuning | Supported | Supported |
| Privacy advantage | Microphones can be turned off | No microphone hardware |
Which should you choose? Pick the Sonos Arc SL if microphone-free hardware matters most. Choose the Sonos Arc if you prefer built-in voice control. Neither has a sound-quality advantage over the other.
