10 Best HDMI Soundbars 2026 in the United States

The Polk Audio Signa S4 is a slim and stylish soundbar designed to enhance your TV's audio with a 3.1.2 Dolby Atmos setup, which means it includes dedicated speakers that create immersive overhead sound, offering a richer experience than basic soundbars. Its wireless 5.9-inch subwoofer adds deep bass, helping bring movies and music to life. With a total power output of 410 watts, it delivers strong and clear audio suitable for medium to large rooms.

One of the standout features is the HDMI eARC support, allowing easy connection to modern TVs, including 8K and 4K models, with just one cable. This simplifies setup and ensures high-quality audio transfer. The soundbar also features Polk's VoiceAdjust technology, which lets you boost dialogue clarity without changing the overall volume – great for catching every word in shows and news. Connectivity options are flexible, including Bluetooth for wireless streaming from smartphones or tablets, plus optical and USB inputs. The design is compact (just over 2 inches tall), so it fits well in front of most TVs without blocking the screen or remote sensors, and wall-mounting is possible.

The Signa S4 offers excellent sound and smart features, though it relies on a wired connection for the subwoofer, which might limit placement flexibility. It is not waterproof, so it should be kept indoors away from moisture. The soundbar’s stereo mode may not satisfy users looking for purely multi-channel surround sound without Atmos effects. This soundbar is a solid choice for anyone wanting a simple yet powerful audio upgrade for their TV, especially if they value immersive 3D sound and easy setup. It suits home entertainment systems aiming to improve movie and music sound without complicated installations.

The Sonos Arc Ultra Soundbar is a high-end option designed to deliver an immersive audio experience for both TV and music. Its main strength lies in its 9.1.4 channel configuration supported by Dolby Atmos, which ensures superior spatial audio, filling the room with well-placed sounds. This soundbar also includes Speech Enhancement for ultra-clear dialogue, which is a great feature if you watch a lot of movies or shows with intricate dialogue.

The design is elegant and modern, blending seamlessly with most home décor without being a distraction. Setting it up is straightforward with a single HDMI eARC connection and helpful guidance from the Sonos app. For control, it offers multiple options, including your TV remote, voice control via Amazon Alexa, and the Sonos app, ensuring flexibility and ease of use. The Sonos Arc also supports various streaming options like WiFi, Bluetooth, Apple AirPlay 2, and Spotify Connect, making it versatile for playing music from different sources.

One potential drawback is that the subwoofer is not included and must be purchased separately if you want deeper bass. Additionally, it is a corded electric device, which might limit placement options to areas near power outlets. It is also quite large, measuring over 46 inches, so it may not be suitable for very small spaces. Despite its premium features and high quality, it does come with a higher price tag, which is something to consider depending on your budget. In conclusion, if you are looking for a top-tier soundbar with excellent audio quality, multiple control options, and modern connectivity features, the Sonos Arc Ultra is a compelling choice, especially if you are willing to invest in additional components like the subwoofer for a complete surround sound experience.

The Sonos Arc Ultra is a powerful soundbar designed for those who want a top-notch audio experience with their TV and music. It offers an impressive 9.1.4 channel setup with Dolby Atmos, which means it can create highly immersive, three-dimensional sound that seems to come from all around you. The sound is clear and detailed, especially dialogue, thanks to AI-powered speech enhancement that helps you catch every word.

It connects easily to your TV using a single HDMI eARC cable, making setup straightforward, and offers multiple ways to control it, including voice commands via Sonos Voice Control or Alexa, your TV remote, or the Sonos app. You also get flexible streaming options like WiFi, Bluetooth, Apple AirPlay 2, and Spotify Connect, which means playing music from your phone or other devices is hassle-free. The design is sleek and minimalist, fitting well on a tabletop without drawing attention away from your screen.

The Arc Ultra itself doesn’t include a built-in subwoofer, but you can add one separately for deeper bass, as well as additional rear speakers to create a full surround sound system. It’s a bit heavy and large, so placement needs some space, but this size helps deliver powerful sound. This soundbar is ideal if you want premium, room-filling audio and smart features, especially if you’re willing to expand your setup over time for an even richer surround sound experience.
