Best Dolby Atmos Soundbar of 2024 [CNET]

Reviews ethics statement

Ty Pendlebury has worked at CNET since 2006. He lives in New York City where he writes about streaming and home audio.

At CNET I test audio equipment from compact soundbars all the way to surround sound speakers systems, but regardless of the device my methodology is largely the same. I always compare products against one or more reference devices that offer the best performance at a similar price. 

When it comes to soundbars, I want to see how well a system performs with music as well as with movies, as most people will want to do both. I watch from a handful of test scenes from 4K Blu-ray or streamed from a 4K streaming service (Vudu, for example) and evaluate aspects such as bass performance and dialogue clarity. I also use a number of test music tracks and evaluate any streaming features such as Bluetooth and Wi-Fi. It’s systems that can perform well with both types of entertainment that inevitably score the highest.

I have tested the following soundbars in the CNET audio lab against models of a similar price. Each of these soundbars are worthy in their own way, but aren’t quite as recommendable as our main picks.

• Sonos Beam Gen 2 ($485) The Beam may only offer simulated height speakers, but it’s the best simulated Atmos I’ve heard yet. The Sonos Beam also offers a lot of features, while the Bose Soundbar 600 and Vizio M512a-H6 deliver even better Atmos performance for the same money. Read CNET’s review of the Sonos Beam Gen 2.
• Bose Smart Soundbar 900 ($725): This is a great Bose soundbar, and it pairs well with the company’s QuietComfort headphones for late-night listening, but it’s simply not as robust as the Sonos Arc. Read CNET’s review of the Bose Smart Soundbar 600
• Bowers & Wilkins Panorama 3 ($999): An excellent soundbar with HDMI connectivity and multiroom music streaming. While music is where this soundbar shines, the system does cost more than the Arc, and its peripherals are expensive.
• Sennheiser Ambeo Plus ($1,200): A cut-down version of the $2,500 Sennheiser Ambeo Max, which offers many of the same features including Chromecast built-in and voice assistance. I found the sound was enveloping and music to be more nuanced than some of the cheaper ‘bars. Yet, at its retail price it’s not quite $600 better than the Sonos Arc, nor is surround sound as convincing as the Max. Read CNET’s first take of the Sennheiser Ambeo Plus.

In the last few years, we’ve seen an explosion in the number of Atmos soundbars. Even better, the prices have finally dipped below $500, making them more affordable than ever. There is a big difference between Atmos compatible and Atmos capable, though. Some of the soundbars can only read the standard but not play it, typically the cheaper models. While the Sonos Beam Gen 2 does a great job of simulating height effects, it pays to invest in a model with dedicated height speakers.

If you’re buying a new soundbar, then music streaming is an important consideration. This can take one of two main formats: Bluetooth, or Wi-Fi. Wireless streaming lets you play music from a multitude of sources, such as Spotify on your phone or iTunes on your computer, via your soundbar. Wi-Fi offers several upgrades over Bluetooth, including the ability to listen in multiple rooms and even control it with a Google Assistant or Alexa.

Many Dolby Atmos soundbars have a smart assistant onboard; these days, it’s usually only Amazon Alexa. Having a smart assistant can make controlling the soundbar easier and also help set the scene by dimming lights and closing curtains. If you use Google Assistant or Siri in your house, then most of these models can be controlled by them, too. Worries about privacy? Either turn off the soundbar’s microphone or get a model without one!

Dolby Atmos can be played over a normal HDMI ARC connection with streaming services, which use the Dolby Digital Plus codec — and when it works it’s great. If you want the full-blooded Dolby Atmos experience then you may need to upgrade to a new TV with an HDMI 2.1 port, as it will enable higher quality Atmos streams from Blu-ray players and gaming consoles.

If you’re a gamer or enjoy watching the latest blockbusters, then yes, a Dolby Atmos soundbar is worth paying more for. But you need to make sure that you have a TV with an HDMI ARC port (for Dolby Digital Plus) and a Dolby Atmos-capable source, such as the Xbox Series X or the latest Roku streamers.

The short answer is HDMI. The long answer is that there are two ways to get Atmos into one of these speakers — the first, and best, is to have a TV with an eARC port (HDMI 2.1). This port is a feature of many new TVs and enables Atmos information to be fed from your TV (via either smart apps or another connected device) to an external speaker. Normal HDMI ARC will work for some streaming services that offer Dolby Atmos. 

On the other hand, if you have an older TV and an Atmos source such as a Blu-ray player, you’ll need a soundbar that has more than one HDMI port. The Vizio M512a enables you to connect external devices directly by HDMI.
