How To Buy The Best Sound Bar

A sound bar is a compact speaker system designed to improve your TV's audio. Sound bars contain several speakers in one long bar-shaped box - much easier to set up than a full home cinema system.

We’ve tested the latest models from all the biggest brands to help you avoid making a costly mistake.

What's the single most important thing you're looking for in a sound bar?Do you need:
- To make dialogue sound clearer?
- A simple model to enhance TV programmes?
- A model that makes films sound great?
- Certain features such as the ones discussed below (e.g. wireless connectivity, surround sound, a subwoofer)?

If your TV isn’t wall-mounted and you have enough space, you may be better off with a sound base because they have larger speakers so they tend to have better sound quality. For more information, check out our best sound bases guide.

Sound bar features to look for

Beyond great audio quality, there are a few things you should expect from a good sound bar.

Wide listening angles and high maximum volume

Many sound bars have a ‘sweet spot’. This might sound like a good thing, but it actually means there’s one specific sitting position at which the sound bar sounds best, and quality deteriorates as you move away from it.

If you regularly share your TV viewing with friends or other family members sitting around your living room, you’ll want to pay attention to our ‘different angles and distances’ scores in our sound bar reviews. This tells you how versatile a sound bar is when you’re not sitting front and centre.

Good speech quality

A common reason for getting a sound bar is to make speech in TV and films sound clearer.

Typical TV speakers can make dialogue sound muffled and unclear. Most sound bars come with an external or built-in subwoofer for extra bass. But the bass can sometimes be too harsh and overpowering, which can leave you straining your ears to make out what characters are saying.

Some sound bars have a voice enhancement setting designed to sharpen dialogue. Not all actually work well though. We evaluate the speech sound quality of each sound bar to weed out models that have below-average speech quality and will leave you resorting to pressing the subtitles button. Our best sound bars make speech sound crystal clear in TV and films.

Wireless connectivity

In addition to wired connections, most sound bars come with Bluetooth. This is great if you want to use your sound bar for listening to music without having to turn on your TV.

More sound bars are coming equipped for wireless multi-room music streaming. By pairing speakers together around the house, you can enjoy seamless access to your music library in multiple rooms.

Sound bars with wi-fi are able to become part of a multi-speaker, multi-room music system. You’ll need other compatible speakers of the same brand in your home to make use of this.

Ease of use

A sound bar that’s easy to use will be a great long-term investment. Look out for fiddly remote controls in particular, as these are easily lost and often have tiny, hard-to-press buttons.

If you’re buying a big sound bar, it might block the signal between your remote control and your TV. Sound bars with built-in IR (infra-red) repeaters negate this problem by forwarding the signal from your remote control to the TV.

Sound bars that have a display and controls on the device tend to be easier to use.

Many sound bars now have simple LED displays that let you switch audio sources and adjust sound settings. But some can be very hard to use, which is something we pay particular attention to in our reviews.

Good-quality connections

Any good sound bar will have at least one digital connector: optical, coaxial or HDMI. These minimise interference compared with lower-quality 3.5mm audio jacks that you find on cheaper sound bars, and allow for special features such as virtual surround sound. The best sound bars will offer HDMI ARC connections. Additionally, models with HDMI-CEC will allow you to use one remote to control both your TV and the sound bar. For more information, read our guide to setting up a sound bar with a TV.

Attractive and practical design

They sit in front of your TV, so sound bars should be well-designed with at least some thought given to style, without making them stand out so much that they become a distraction.

Furthermore, any buttons on the sound bar itself should be within easy reach and not require you to have to contort your body into an uncomfortable position to make adjustments or change audio sources.

Sound bars with Dolby Atmos

Dolby Atmos is the newest innovation in surround sound and is one of the most sought-after sound bar features. A sound bar with Dolby Atmos should create a convincing surround sound experience that matches a multi-speaker home cinema set-up.

Originating from cinema theatres, it’s described as object-based sound meaning that the movement of objects in films will sound very realistic and it bounces sound off the walls and ceiling to create an immersive surround sound experience. So rain and bullets in films and TV can be heard and felt above and around you.

We’ve tested these models that have Dolby Atmos. Some also have DTS:X, another ground breaking surround sound format. Among these are a Best Buy – and a Don’t Buy.

Sound bars with voice assistants

Built-in voice control is becoming an increasingly popular sound bar feature. A sound bar with built-in Amazon Alexa works as a voice assistant in the same way that an Amazon Echo or Echo Dot would, allowing you to use voice-control to play, pause and rewind TV.

You can use your voice as an alternative to the remote. Just ‘speak to the room’ to manage your day and get information. Find out how these models with built-in Alexa did in our tests:

Some sound bars are compatible with Alexa-enabled products, meaning that if you own an Alexa product like an Amazon Echo, you can use it to control the sound bar. Unlike with models that have Alexa built-in, you’ll have to speak to the Alexa-enabled product rather than directly to the sound bar.

If you already have an Alexa product, take a look at these sound bars that are compatible with Alexa to see if we recommend them:

Additionally, some sound bars have Google Home built-in or are compatible with it so, if you own a Google Assistant, you can use it to control the sound bar with your voice.
