Take it from us: No home cinema is complete without a soundbar. Even the most premium smart TVs lose something in the sound. Their speakers never quite match the visuals. That’s because those speakers are usually built into the back or bottom of the TV, which doesn’t equate to quality sound. Even with TV manufacturers thinking up new ways to sex-up the sound — such as audio that seems to be comes directly from the action onscreen — smart TVs are meant to be paired with a good soundbar.
A soundbar will be the foundation of a great sounding home cinema, with the option to add a subwoofer (sometimes included) or additional speakers. In this kind of setup, the TV itself becomes just one component in a whole system of cinematic-quality speakers.
But how do you choose a soundbar? There are so many models available. It’s hard to pick apart all the jargon and specifications — especially if you’re a soundbar novice. But listen up, because we’ve done some important research to help you decide. Here’s some useful information and a round-up of the best soundbars you can buy right now.
What is a soundbar?
Instead of a bunch of speakers dotted around the room or a chunky amplifier, a soundbar sits under your TV. You can also mount them on the wall, if that’s how you’ve for your smart TV set-up. Designed specifically for TVs, with a wider build for improved acoustics, soundbars offer a superior quality over built-in speakers — a crisper, more nuanced sound with resonating bass and clearer dialogue.
Do soundbars provide surround sound?
Soundbars can absolutely be integrated into a surround sound setup. Surround sound puts you in the centre of the action by having speakers literally surrounding you, or dotted around the room, so the sound comes from all directions. Soundbars can be linked (often wirelessly) and you’ll find that some brands make it especially easy to connect with other speakers within their range. However, as you’ll read below, you may not need to connect your soundbar with other speakers for surround sound.
What is HDMI ARC and eARC?
These are terms you’ll see a lot when shopping for decent audio-visual tech. ARC stands for Audio Return Channel. It’s essentially an HDMI technology that allows you to connect your TV to a speaker via a single HDMI cable without needing multiple optical cables. Meanwhile, eARC—or Enhanced Audio Return Channel—is a souped up version that utilises the more advanced HDMI 2.1 technology. In basic terms, it gives you a bigger, faster bandwidth for even higher quality. This is particularly good for audio formats such as Dolby Atmos, or next gen gaming.
What is Dolby Atmos?
This is a fantastic innovation in surround sound technology, derived from cinemas. Any TV, speaker, or soundbar that’s equipped with Dolby Atmos is essentially a premium bit of kit. Dolby Atmos bounces sound off the walls to create a 3D soundstage and truly immersive experience. Atmos-equipped soundbars have speakers that fire upwards and bounce sound off the ceiling. Dolby Atmos soundbars essentially create a cinema-like experience without the need for multiple speakers.
What does pass-through mean?
While most people tend to plug all their devices (gaming console, Blu-ray player etc) into the TV then run audio from the TV to the soundbar, pass-through allows you to plug these devices directly into the soundbar and run an HDMI out from the soundbar and to the TV. This passes the video signal through the speaker to the TV while giving you uncompressed audio. In other words, the best sound possible. But not every soundbar is equipped with pass-through. It’s usually reserved for premium models.
Do soundbars have a voice assistant?
Many soundbars have Alexa and Google Assistant, so you can ask them to adjust the sound or even change the channel. Some soundbars will also connect to music streaming apps or double up as a hub for your smart home.
How much does a soundbar cost?
You can spend around £200 for basic soundbars, or go into the thousands. It all depends on the kind of tech and quality of sound you want. This roundup includes options for most budgets, so there’s definitely something for you here.
What is the best soundbar?
You need to ask yourself several questions before making a decision — questions about audio quality, smart features, connectivity, and price. Whatever features suit you and your watching habits best, there’s a good option listed below.
These are the best soundbars in 2025.
