The company continues to innovate, creating wireless speakers, home theatre systems, headphones, architectural components, and integrated home audio solutions that revolutionise how people listen and connect to sound.

Noise-cancelling headphones have become an essential accessory for many people, especially those seeking solace in their music or craving a quieter environment amidst the hustle and bustle of daily life. But as you delve into the world of noise cancellation, you’ll likely be confronted with a heap of audio jargon and confusing technical terms. In this blog post, we’re going to demystify noise-cancelling technology, explain how it works, and offer a few tips for choosing the right pair of noise-cancelling headphones for your listening needs.

Types of noise cancellation on headphones

There are two main types of noise cancellation, both of which play an equally important role when it comes to blocking external sound.

 barrier between you and any unwanted noise. Picture yourself sitting at a restaurant when suddenly the fire alarm goes off. The sound is unbearably loud, so you instinctively cover your ears with your hands to muffle the noise. By doing so, you’ve created a physical barrier between your ears and the sound of the alarm. The ear cups on over-ear headphones work similarly in this way, but the degree to which noise is blocked depends largely on how tight the seal is around your ears.

 is far more intricate. This technology relies on a complex system of microphones, sound processors, and speakers to effectively neutralise external noise. Let’s break it down further.

You don't need to be an audio engineer to understand the basic principles of Active Noise Cancellation (ANC) technology. A good analogy will do. For the sake of this blog, all you need to know are the rules of the game tug of war. If it’s been awhile since you’ve played this in a schoolyard, let us provide you with a brief refresher.

In a game of tug of war, two teams are pitted against each other in a test of strength. Each team is positioned on opposite ends of a rope, with the goal of pulling the rope in the direction away from the opposing team.

If both teams tug with the same force, the rope won’t move in either direction because each team’s strength is 

. Soundwaves work in a similar way: If one sound wave meets another soundwave that’s the same in frequency and opposite in amplitude, the two sounds will cancel each other out.

While a game of tug of war by no means encapsulates the complexity of sound physics, this should at least give you a basic idea of how Active Noise Cancellation works. Headphones with ANC use tiny microphones inside the ear cups to continuously analyse the sound of your surrounding environment. The microphones identify the frequency and amplitude of the external sounds, then ANC uses this information to create a soundwave that’s the exact opposite. This contrasting soundwave gets played through the internal drivers on your headphones and, voilà, the unwanted noise is eliminated. The diagram below should help visualise what this process looks like.

An outside soundwave reaches the headphones. Active Noise Cancellation in the headphones layer a soundwave that opposes the outside soundwave, resulting in no noise entering the ear.

Can ANC work with no music or sound playing?

The beauty of noise-cancelling headphones is that they work even when no music or sound is playing. But most headphones with ANC are designed to work in tandem with some degree of ambient noise due to the ‘masking effect’, which refers to the phenomenon where your brain perceives the absence of sound when it’s masked by an opposing sound.

Say you’re sitting on a crowded train and the person seated across from you is talking on the phone. When you put on your headphones, you’re still likely to hear a bit of muffled chatter. But once you start playing some music, your neighbour’s conversation suddenly disappears. This is because your brain is now taking in more sensory input (your music) and is less focused on the conversation happening in the background.

Ultimately, the effectiveness of ANC will vary depending on the quality of the headphones and the surrounding noise levels. In quieter environments, such as a library, ANC can still noticeably reduce background noise without any music or sound playing. But in louder environments, playing some white noise or other type of ambient sound allows ANC to work its best. A quick search on your preferred music service should provide you with a variety of options.

Where do noise-cancelling headphones work best?

Noise-cancelling headphones work in a variety of environments where external noise may disrupt your concentration or relaxation. Here’s a list of some places where noise-cancelling headphones are especially valuable:

But noise-cancelling technology won’t excel in 

 environments. Let’s discuss some of the pitfalls you should expect from noise-cancelling headphones.

Why do I still hear noise when using noise-cancelling headphones?

As previously mentioned, ANC is most effective when some amount of ambient noise is present, whether from your headphones or surrounding environment. This is because ANC excels at blocking 

 sounds, like the hum of an aeroplane or drone of an engine. These low-frequency sounds produce long soundwaves, which are a lot easier to block because they tend to be more constant in your environment, ultimately giving your headphones enough time to analyse and produce the best opposing soundwave.

 sounds — like the honk of a car horn or wail of a crying baby — tend to happen much more sporadically. These sudden noises are more difficult for ANC technology to block because the sound is often gone before your headphones have had enough time to produce a defending soundwave.

To summarise, passive noise blocking methods (like ear muffs) are best at drowning out high-frequency sounds, while ANC is best at reducing low-frequency sounds. This is why choosing a high-quality pair of noise-cancelling headphones is especially important so that sound is both 

 blocked. For example, Sonos Ace features an adjustable headband and memory foam ear cushions to create an exceptional acoustic seal that passively blocks high-frequency sounds, while Active Noise Cancellation handles the lowest frequencies. You get the best of both worlds for the most serene listening experience.

How Do Noise-Cancelling Headphones Work?

, you may be wondering which type of speakers make the most sense for your listening style. There are lots of features to consider, from the speaker’s design and size to its connectivity options. But before you research any further, your first step should be deciding whether you want active speakers or passive speakers.

In this guide, we’ll clarify the difference between active speakers and passive speakers. We’ll also review some key factors to consider when deciding between the two. Whether you’re dreaming of a dedicated listening space or a 

 that plays music or podcasts throughout your home, we’ll help you figure out which speaker type is right for you.

, are speakers that contain a built-in amplifier, or ‘amp’ for short. Because the amp is already inside the enclosure, an active speaker doesn’t require an external amp as a source of power.

If your speakers plug into an electricity source, there’s a good chance that they come with a built-in amp. Most Sonos speakers fit this description, including Era 100 and Era 300.

Why is an amp necessary? Most audio sources send an electrical signal to speakers that tells them which sounds to produce. But this signal is usually too weak to actually produce sounds on its own. An amplifier boosts the signal’s power, which ultimately results in the sounds you hear from your speakers.

If you favour a streamlined setup with fewer components, an active speaker may be right for you. Not only are active speakers easier to install out of the box, but they also eliminate any concerns about finding an amp that works in harmony with your speaker.

This all-in-one approach to a speaker system is appealing to many listeners, but you may prefer to tinker and tweak your system’s individual components — from the speakers right down to the amp. If so, passive speakers could make more sense.

, lack a built-in amp, meaning they can’t 

 amplify the signal coming from an audio device. To use passive speakers as part of your sound system, you’ll need to rely on an 

 or AV receiver to power the audio signal.

Passive speakers come in all shapes and sizes. For example, in-ceiling and in-wall passive speakers are designed to be unobtrusive and to blend seamlessly with your home décor. Aside from their appearance, passive speakers may be engineered to reproduce specific frequencies of sound. For example, 

 specialise in low frequencies, while tweeters specialise in high frequencies.

So why use passive speakers if you’ll end up needing more components? Because for some listeners, this is precisely the point. A passive speaker system offers the flexibility to mix and match a range of specialised components, or to upgrade to a higher-quality amp in the future without also having to replace the speakers.

This flexibility comes at the cost of convenience though. Passive speakers typically require a wired connection and a more complex setup process. To also avoid damaging your speakers or external amp, passive speakers must be paired with an amp whose power output matches the speakers’ impedance. You shouldn’t have any issues finding an amp that falls within your speakers’ specified impedance range, but it’s another thing to worry about.

Key considerations between active and passive speakers

Now that we’ve defined our categories, we can tackle a central question: Should you buy active or passive speakers? Active speakers are probably a better solution for simple, everyday listening, but passive speakers could make more sense with certain audio setups. Let’s take a closer look.

Active speakers are usually considered easier to set up than passive speakers. For one, the built-in amp eliminates the need to connect an external amp. This isn’t just a matter of “one component is easier to keep track of than two components.” Because the built-in amp is already matched to the speaker’s drivers, you don’t need to deal with equalising or adjusting the settings on your amp to achieve a high-fidelity sound.

With that said, if you prefer an out-of-the-box solution that will sound good without much tinkering, an active speaker is probably the way to go.

If your speaker’s looks and location matter as much as its sound, passive speakers may offer more flexibility. Because these speakers don’t need to house a powered amp, they tend to come with slimmer and less obtrusive enclosures that can be installed discretely throughout the home.

 that are discreetly installed into a room’s walls or ceiling. These types of speakers are often passive to allow for more customisation in their placement. Of course, some active speakers, 

, also feature a sleek design that can seamlessly blend into most home theatre setups.

You can achieve high-fidelity sound with both active and passive speakers.

Yes, passive speakers allow for more customisation. Their enclosures also often have room for larger drivers, which are typically associated with better sound quality. But unless you’re an audio pro or have a good ear for balancing frequencies, you may find it more difficult to achieve a balanced, neutral sound with passive speakers.

Active speakers also have some design benefits that may enhance their sound quality. Aside from their matched amps and drivers, active speakers don’t require long speaker cables leading from the amp to the speaker. These cables are included inside the enclosure and are usually quite short. In general, the shorter the cable, the better the sound quality, so this is typically a good thing.

Whether you choose to go with active or passive speakers, Sonos has a solution for you.

Active vs. Passive Speakers: Which Is Best For Your Home?

Adding a subwoofer to your sound system can make all the difference in your listening experience, clarifying both low and high frequencies. (Need a bass refresher? Check out our 

 in your home, you may have come across the Phase Control setting in the Sonos app. If you’ve ever wondered, “What does phase mean for a subwoofer? Why would I want to adjust it?”, this article is for you.

Phase refers to the timing difference between low-frequency sound waves from your subwoofer and higher-frequency sound waves from your main 

. Adjusting the phase changes where a sound wave begins. This affects how the different frequencies merge and how you hear them.

Phase adjustments in a subwoofer are crucial for finding the sweet spot where the bass blends seamlessly into the overall sound experience. If you have your subwoofer bonded to a soundbar, it’s helpful to be attuned to the phase, as the precise timing and integration of sound effects can drastically change your home theatre viewing experience.

Why do I need to change the phase on my subwoofer?

Room acoustics play a significant role in how sound waves travel and interact with the environment. If your signal is in phase, the sound will feel very full. If the signal is out of phase, some frequencies are cancelled out, which could negatively impact the clarity and fullness of the sound.

You'd typically adjust the phase of your subwoofer in the following instances:

Rearranging the room where your speakers are placed

Adjusting the phase control for a traditional wired subwoofer can be like finding the right combination to a lock. You might need to try it a few times before it feels just right. Typically you’d slowly adjust the phase knob while playing a bass-heavy track. You’d want to also test the adjustments by listening where you’d usually be, as the effect might vary around the room.

Adjusting the phase control for Sonos Sub or Sub Mini is more like flipping a switch. Open the 

 and navigate to the product then select Settings > Advanced Audio > Sub Settings. Choose 0° or 180° and listen for the tone; it will help you gauge the adjustment.

If you use Trueplay™ to tune your setup, you don’t have to make any adjustments to the phase control and this setting will be disabled. Trueplay will optimise the phase of your subwoofer — and any bonded speakers — for the unique acoustics of your listening space.

, bringing greater depth and clarity to music, TV, films, and more. But for the best possible listening experience, you want to make sure every setting is just right. The Sonos app makes that easy, letting you fine-tune the phase control yourself or doing it for you with Trueplay.

You want that cinema-quality sound experience at home. So, which speakers do you need? How many? And where exactly do you place them? Worry not. We’re here to help answer these and all your home theatre questions. In this blog, we’ll look at the two most popular surround sound setups — 5.1 and 7.1 — and explore the differences, which spaces they work best in, and how to create your own surround sound system at home for your next film night. Let’s get into it.

Picture yourself in a cinema, with an action scene playing out on-screen: fighter jets are weaving through the air and pilots are speaking into muffled headphones. In the cinema, the sound is astounding — the dialogue is crisp, the jet engines sound as if they’re passing overhead, and you can hear the enemy planes approaching from behind before they appear on the screen. This is surround sound, powered by speakers strategically placed around the room to create a truly immersive listening experience.

Even better, you can achieve something similar at home. You’ll just need a few speakers and a little bit of know-how. That’s where understanding 5.1 and 7.1 surround sound comes in. Knowing what these setups are and your options for creating them can help you build out your system at home.

“Our years selling at markets gave us a chance to slowly build our business and to figure out what worked,” says Bettina. “Selling at markets was up close and personal.”

The first number in each configuration (i.e. the ‘5’ in 5.1) refers to the number of ear-level channels — or points of audio, such as a speaker — in the system. The second number refers to the presence of a subwoofer. So, a 5.1 system includes three front channels (left, right, and center) and two rear channels (left surround and right surround). While a 7.1 system has an additional two channels (left side surround and right side surround). These are typically positioned between your ‘front stage’ (soundbar) and ‘rear stage’ (surround speakers). The image below should help visualise how a 5.1 comes together in your living space.

Diagram illustrating a typical 5.1 home theatre setup

Absolutely. As you’ve probably guessed, a 7.1 surround sound setup has the ability to really envelop listeners in audio, thanks to those two extra channels. Think of these setups like a LEGO® structure. A 5.1 system will deliver quality, immersive audio, but when you build on that system, you add additional depth and detail.

Both a 5.1 and 7.1 setup will surround you in sound with the help of front and rear speakers, but the 7.1 system’s additional two channels provide that extra bit of immersion. This gives you that feeling of being in the centre of whatever is playing out on the screen. It also makes the film or show feel more realistic. Because in real life, sound doesn’t just come at us from one direction.

Choosing between 5.1 and 7.1 surround sound

Let’s explore some important factors to consider when selecting your surround sound system.

If you have a small space, consider a 5.1 setup. This system will easily fill your room with sound and, depending on which speakers you choose (more powerful speakers create more powerful sound), you can still render a similar sound quality to a 7.1 setup. If your space is larger, however, you may want a 7.1 system to really fill the area with sound.

It goes without saying that the more complex the surround sound system, the more money you’re likely to end up investing. Generally speaking, a 5.1 setup will be more affordable than a 7.1 setup. There are naturally exceptions to this. For instance, if you were to opt for a more powerful soundbar or rear speakers, a 5.1 system could cost more. Speakers and subwoofers range in price depending on their size, power, and features, among other things.

How much you’re looking to spend may also help you decide where at home to set up your system. For instance, if you have a smaller budget, consider creating your film space in a smaller family room versus a more spacious basement.

You’re spending time and money building out your surround system, so it makes sense to consider the variety of listening experiences it will provide. Are you planning to listen to music from these speakers in spatial audio? If so, consider Dolby Atmos-supported speakers as part of your setup. These speakers will make your system more versatile for the times you switch from films to music.

You’ll get crisp dialogue without having to cup your ear or turn on subtitles. This setup puts you in the centre of it all with life-like, spatial sound with Dolby Atmos and hair-raising bass.

Now that you have the basics, it’s time to build your system — and dream of the fun you’ll have with it. Whether you’re hosting a film night or bingeing on a weeknight show, surround sound turns up the emotion on whatever’s on-screen to bring you into the action. Let’s be honest, sometimes we need that little extra something to pull us in and help us unplug from our day. So, whether you prefer action films or psychological thrillers, sound from all angles of your room will add that extra bit of adrenaline. Visit sonos.com to discover Sonos

5.1 vs 7.1 Surround Sound: What's the Difference?

You’re sitting in the theatre. There’s a high-speed car chase playing on the screen in front of you, and you can hear tyres screeching to your right and police sirens blaring from behind. But how? This is thanks to surround sound — with speakers placed strategically all around the theatre. Each speaker projects audio in different directions, angles and heights to deliver a more realistic and immersive sound experience. In this guide, we’re breaking down how you can create this same cinematic experience at home and feel like you’re in the middle of all the action.

In short, surround sound helps you feel like you’re in the middle of whatever is happening on screen. As its name suggests, this technique is used to create an immersive audio experience that feels like it’s completely surrounding you. When you visit the theatre, a number of speakers — in some cases, 

 — are strategically positioned around the room to project sound in every direction. While this experience is most familiar at the theatre, you can also achieve immersive surround sound at home with the right speakers and the 

You can configure your surround sound system in a variety of ways based on the size of your room, the sound experience you want to achieve, and your budget. The two most common surround sound setups are 

First things first: What do these numbers mean? Essentially, these figures indicate how many points of audio — or ‘channels’ — are within a surround sound system. The first digit in each configuration denotes the number of channels in a system, while the second refers to the presence of a subwoofer. So, for example in a typical 5.1 system, three front speakers (or a soundbar, which delivers the left, right, and centre channels), two rear speakers, and one subwoofer make up this setup. (For a greater breakdown on channel configurations, check out our 

Generally speaking, the number of channels in a given setup is a strong indication of how immersive the surround sound experience will be. Let’s take a closer look at each.

A 5.1 system is considered a standard layout — with most films mixed for this surround sound experience. In this setup, the dialogue will sound crisper, effects and other ambient audio will appear to be coming from behind and in front of you, and you’ll feel like you’re enveloped in the action happening on-screen. This is thanks to five channels — or points of audio — and one subwoofer. Imagine the setup having three channels in front of you and two behind for all-around audio, plus a single subwoofer to deliver those low-frequency sounds such as big explosions or deep voices.

For most home theatre setups, this system is a solid choice. The three front channels and two rear channels will easily fill your room with sound.

Because surround sound is all about, well, surrounding you in sound, more channels will create a more immersive viewing experience. The two additional channels in a 7.1 setup will fill some of the gaps in your sound experience. However, it’s worth noting that some speakers can provide multiple points of audio without the need for additional speakers. For example a soundbar covers your three front channels (left, right, and centre) despite being a single speaker. Some rear speakers can also cover multiple points of audio, eliminating the need for individual speakers and a whole lot of wiring.

Does surround sound actually sound better?

Yes, surround sound does make a difference for those times you’re watching a film and want to be immersed in sound. Let’s take a look at why that is.

With a stereo system, all of your sound comes from two channels: the left and the right. This is great if you’re listening to music in the car or on a pair of 

. But when you’re watching a film, you want to feel engulfed in the action, and surround sound does that for you. Surround sound is less directional and more dynamic than 

, sending audio in front of you, above, and behind instead of just to the left and the right. This creates an overall more realistic sound — mimicking the way you experience action in real life.

Adding a soundbar to your TV will give you 

, enhanced clarity, and deeper bass. But all the sound is only coming from the soundbar in front of you. Adding rear speakers for surround sound will give you that all-encompassing effect, thanks to audio coming from many different angles around the room and sound actually coming from behind you.

Picture yourself in the theatre again watching that car chase. At this point in the scene, a police helicopter is now hovering above the vehicles. It feels as if the propellers are whirring overhead. But how do you replicate this same feeling at home? This is where height channels and 

In a more advanced home theatre system, like a 7.1.4 setup with Dolby Atmos, you'll notice the addition of a third digit, which represents the number of overhead speakers or 

. These speakers are typically placed in each corner of the room and help add the feeling of height to your viewing experience.

If this sounds like a lot of speakers for one room, that’s because it is. But with the help of advanced technology and acoustic hardware, you can create this same experience with less speakers using 

 is a spatial audio technology that allows sound objects to be placed on a three-dimensional canvas and moved around in space. This adds a third overhead dimension to 5.1 and 7.1 surround sound setups. As a result, sound travels more naturally around the room as it would in real life, creating a more realistic sound experience for you as a listener.

The benefits of a soundbar are plenty. For starters, it performs the work of a right, left, and centre speaker — saving you space and potentially money. It creates that immersive surround sound experience without the need for three individual speakers (with their accompanying wiring) in front of your TV. And soundbars won’t cramp your style. The understated design blends in with existing decor, and its thin construction means it will fit nicely under a TV or can be easily mounted on a wall.

Of course, not all soundbars produce the same experience. If you're planning to tuck your speaker into a media stand, you'll want to choose 

 so that furniture won’t block the soundwaves. But if you want to create that truly immersive theatre experience, go with a 

. These speakers are designed with upward-firing drivers to project sound all around the room.

A soundbar on its own can dramatically improve the clarity and quality of your audio, whether you’re streaming a film or listening to music. But if you want sound that comes from all directions, consider adding a couple of rear speakers. Rear speakers magnify all those ambient sounds that really bring you into the film — rustling wind, a leaking tap, or coffee-shop chatter. If you’re a fan of scary films, you know the importance of those details for creating suspense.

, you’ll need to position them on either side of your seating or behind you. Make sure that the side and upward-firing drivers are clear of anything that could block them. (Depending on the speaker, you can also mount them higher and position them toward wherever you’ll be sitting.) You can easily connect 

Subwoofers are great additions to your surround sound setup because they really help you feel the audio. A 

 also enhances the sound of your other speakers by shouldering some of the work. That is, subwoofers produce some of the lower sound frequencies, so your other speakers can focus on delivering mid-range sounds. Absolutely brilliant, right? When choosing a subwoofer, be aware that they range from 

 to large with varying levels of power. What size works best for you will depend on the rest of your setup, the size of your room, and your budget.

How Sonos does 5.1 and 7.1 surround sound differently

While 5.1 and 7.1 surround sound systems usually require as many speakers placed around the room as channels, Sonos innovation delivers the same immersive surround sound experience with less hardware. For example, a Sonos 

 does the work of three speakers by reproducing the centre, front left, and front right channels. This means a Sonos home theatre system is not only easier to set up, but also fits and looks better in your space.

Another standout feature for Sonos is the ability of select speakers to render additional

To achieve 5.1 surround sound with Sonos, you’ll need the following products:

A soundbar for the centre, front left, and front right channels.

Two rear speakers, one for the rear left channel and another for the rear right.

A subwoofer for the low-frequency effects channel.

This configuration will deliver crisp dialogue from the centre, deep bass from the subwoofer, and a three-dimensional sound experience all around you.

For even more immersive Sonos surround sound, you don’t actually need more speakers. You just need the right speakers that support spatial audio. Speakers such as 

, for example, have the acoustic architecture to create a wider soundstage and the processing power to precisely render individual sounds all around the room. When you play Dolby Atmos content through these speakers, you’ll feel as though you have two additional side speakers — one to your left and another to your right — as well as four speakers overhead. It’s not just 7.1 surround sound. It’s 7.1.4.

If you're looking to take your surround sound setup to the next level, you can go beyond 7.1 with a 9.1.4 configuration. This setup adds even more rear and height channels, creating an incredibly immersive experience that wraps you in sound from every direction. With
