Sony WH-1000XM5 vs Bose QuietComfort 45

The short answer

Sony and Bose make two of the best-known noise-cancelling headphone families in the world. The Sony WH-1000XM5 and the Bose QuietComfort 45 are the pair most people compare, and both do the main job very well: they quiet the world around you so that music, calls and podcasts are easier to enjoy.

The difference is in the personality. The Sony tends to appeal to people who like features, settings and flexible sound. The Bose tends to appeal to people who want something simple, comfortable and calm. Neither choice is wrong, and which one wins for you depends on what you do all day.

A word of honesty first. Both of these models have been on the market for a while, and both companies have released newer headphones since. Prices, stock and even the exact lineup change. We use this pair as a clear example of two design philosophies, and we tell you where to check the current versions.

As always, our comparison is based on published specifications, official documentation and public information. We do not claim to have lab-tested these headphones, and we do not invent measurements. The figures below are the makers' stated numbers unless we say otherwise.

Two companies, two habits

Sony is a huge electronics company that makes cameras, TVs, game consoles and audio products. Its headphones often arrive packed with technology: many microphones for noise cancelling, support for high-quality wireless codecs, and an app with many options. Sony likes to give you control.

Bose started with audio and noise reduction, and it built its name on comfort and quiet. Its headphones are usually simpler. You get a clean design, solid noise cancelling, familiar controls and fewer things to adjust. Bose likes to make things easy.

These habits show up in everything: the shape, the buttons, the app and the way they sound. Keep them in mind as you read on, because they explain most of the differences.

Noise cancelling

This is the main reason people buy these headphones, so it deserves the most attention.

Active noise cancelling works by using microphones to listen to the outside world and playing an opposite sound to cancel it. It is best at steady, low sounds such as aircraft engines, train rumble, air conditioners and fans. It is less effective against sudden or high sounds, like voices, clanging dishes or a baby crying.

Both headphones cancel noise strongly, and in everyday use, either will make a noisy commute much calmer. Many reviewers have praised Bose for very strong and natural-feeling cancelling on low rumble, and Sony for excellent cancelling across a wider mix of sounds, helped by its larger number of microphones. Differences between them are small enough that, for many listeners, comfort and features matter more.

Both include a transparency mode, which lets you hear the outside when you need to, for example at a station or a shop counter. Sony offers adaptive options that change the level depending on what you are doing. Bose gives you a simpler Aware mode.

One thing that surprises people is that noise cancelling can create a mild feeling of pressure for some listeners. If you are sensitive to this, try the headphones before buying, or buy from a seller with a clear return policy.

Comfort and fit

Comfort decides whether you wear headphones for ten minutes or for ten hours. Both models weigh around a quarter of a kilogram, which is light for over-ear headphones, and both use soft pads and a padded headband.

Bose is widely known for comfort, especially on long flights and work days. Its pads and headband feel soft, and the clamping force is gentle. Sony is also very comfortable, and the XM5 uses a wide, soft headband and a design that distributes weight well. Some people find the Sony slightly looser, and others find it more secure.

Head shape, glasses and hair all change the experience. Glasses wearers should pay attention to how the pads sit around the frames, since a poor seal reduces noise cancelling and can be uncomfortable.

If you can, try both for at least fifteen minutes. Comfort cannot be judged from a spec sheet, and it is the one factor you will notice every single day.

Sound

Sound is personal, but there are general patterns that many listeners describe.

Sony headphones are often described as having a lively, detailed sound with strong bass and a lot of clarity in the mids and highs. The app includes an equaliser, so you can change the sound to match your taste. Support for higher-quality wireless audio, such as LDAC on compatible devices, can deliver more detail when your phone supports it.

Bose headphones are often described as having a smooth, balanced and slightly warm sound, with a relaxed character that is easy to listen to for long periods. The Bose app includes a simple equaliser with a few bands, enough for light adjustment but not as detailed as Sony's.

What does this mean? If you like to tweak the sound and listen for detail, Sony gives you more to play with. If you prefer something pleasant out of the box and do not like to adjust settings, Bose is easier.

Remember that wireless codecs matter only if both your headphones and your phone support them. A phone that does not support LDAC will use a standard codec, and the difference in sound may be small for casual listening. For more on this, read our wireless audio guide.

Controls and design

The Sony XM5 uses touch controls on the right ear cup, with swipes for volume and taps for play and skip, plus a button for noise control and power. They are convenient and neat, though some users find that touch controls can be triggered by accident, especially in cold weather or while wearing gloves.

The Bose QC45 uses physical buttons and a switch. Buttons give a clear click and are easy to find without looking. Many people prefer that for use on the go.

The cases and folding design differ too. The Bose headphones fold flat and take less space in a bag. The Sony XM5 uses a design that swivels but does not fold in the same way as its earlier model, so the case is a little bigger. If you travel light, check the case size.

Both come in a few colours, with a clean and understated look. Sony's finish tends to look more modern and minimal, and Bose's looks classic and familiar.

Battery and charging

These numbers are the makers' claims, and real battery life depends on volume, features and temperature. Both are enough for a long flight and several days of commuting. The Sony has an edge on paper, and its quick charge is handy if you forget to plug in overnight.

Both can be used with a cable, which is helpful for planes with in-flight entertainment, for gaming or when the battery runs out. Check which cables are in the box, since not every package includes every cable.

Connectivity and apps

Both headphones connect by Bluetooth, can be paired with more than one device and switch between them, which is useful if you use a phone and a laptop together. Multipoint connections can behave differently depending on your devices, so test it with the ones you own.

The Sony Headphones Connect app offers many options: equaliser, adaptive noise settings, button customisation, sound modes and more. Some people love the control, and others find it a lot to take in. The Bose Music app is simpler, with the key controls clearly laid out.

Software updates can add features or fix issues on both. Keep the headphones updated through the app, and read what each update changes.

If you use an iPhone, both work well with standard Bluetooth. If you use Android, check codec support on your phone. If you mostly listen on a laptop for calls, pay attention to how each handles multipoint and microphone quality.

Calls and microphones

Many people use headphones for video meetings, so call quality matters. Both models use several microphones and processing to pick up your voice and reduce background noise.

In general, results are good in quiet and moderately noisy places, and weaker in strong wind or loud streets. Sony's design with more microphones aims to isolate your voice well, and Bose's is also strong for calls. Reviews on call quality differ, and the result can also depend on the app you use for calls.

If calls are a main use, test your own voice in a call with a friend, in the places you really use them. Ask what they hear. A short test tells you more than a feature list.

For serious audio recording, such as podcasts, a dedicated microphone is better than any headphone mic. See our podcast guide for what to use.

Travel and everyday life

These headphones are travel companions, so think about the trip.

For long flights, noise cancelling and comfort matter most, and both do well. Check the case size, since a bulky case is annoying in a small bag. A carry case that fits a charging cable and an airline adapter is helpful.

For the daily commute, quick charging and easy controls matter. Physical buttons suit people who change tracks while holding a bag or wearing gloves. Touch controls suit people who like a clean, simple surface.

For the office, look at call quality, multipoint and comfort over many hours. For the gym, over-ear headphones are not ideal, because they can feel warm and are not designed for sweat. Our headphone guide covers other types.

At home, either can work with a laptop, a TV or a phone. If you want TV sound without disturbing others, check how the headphones handle latency, which is the delay between picture and sound.

Build, repair and how long they last

Both are mostly plastic with metal sliders, and both are made to a decent standard. As with all headphones, the parts that wear first are the ear pads, the headband cushion and the battery.

Pads can often be replaced, which extends the life of the headphones considerably. Check whether replacement pads are available in your area. Batteries lose capacity slowly over years, and replacement may need a service centre.

Care helps a lot. Keep the headphones in their case, do not leave them in a hot car, avoid pulling the cable at an angle and clean the pads gently. Do not expose them to rain or sweat unless they are rated for it, and these models are not made as sports headphones.

Also check the warranty and who handles it locally. Headphones bought from an unofficial importer may not come with a valid local warranty.

Newer models and what to check

Technology moves fast, and the headphones above are no longer the newest from either company. Sony has released later versions in its WH-1000X range, and Bose has released newer QuietComfort headphones, including premium models with additional features. Newer models often improve noise cancelling, call quality, battery life or codec support, and they may cost more.

Older models can be very good value, especially when the price drops. If you can find a good one from a trusted seller with a warranty, the saving may be worth more than a small improvement in features. If you want the latest, compare what has actually changed, instead of assuming that new means better for you.

Before you buy any pair, check the exact model name on the seller's page, the warranty, the return policy and whether the product is new or refurbished. Our audio guides cover other options.

Looking after your hearing

Noise cancelling has a real health benefit that people overlook. In a loud place, most of us turn the volume up to hear over the noise. Cancelling the noise lets you listen at a lower volume, and that is easier on your ears.

A common guideline is to keep the volume at a level where you can still hear a person next to you, and to take breaks during long sessions. Many phones have a feature that warns you when the volume has been high for a long time. If you notice ringing in your ears, muffled hearing or pain after listening, lower the volume and talk to a doctor if it continues.

Transparency mode is also useful for safety. When you walk near traffic or cycle, switch it on so that you can hear what is around you. Wearing noise-cancelling headphones at full strength on a busy road is a risk.

Spotting fake headphones

Popular headphones are copied a lot. A fake pair can look almost the same in photos, but it sounds poor, has weak noise cancelling and may fail quickly. It will also have no real warranty.

• Be wary of a price far below what other sellers ask.
• Buy from official stores or well-known retailers with clear return policies.
• Check the box, the printing and the serial number against the maker's information.
• Test the pairing, the app and the noise cancelling in the first days.
• Keep the receipt and box in case you need to return them.

If the app will not recognise the headphones or key features are missing, treat that as a red flag and contact the seller quickly.

Cleaning and daily care

A little care keeps headphones comfortable and fresh. Wipe the pads with a slightly damp, soft cloth now and then, and let them dry in the air. Do not use strong cleaners, since they can damage the pad material. Keep the microphone holes clean with a dry soft brush, and never push anything sharp into them.

Store them in their case, not squeezed at the bottom of a bag. Avoid leaving them in direct sun or a hot car, because heat shortens battery life and can warp parts.

If the pads start to crack or flatten, think about replacing them. It can make older headphones feel almost new, and it is cheaper than buying a new pair.

TV, gaming and delay

Wireless audio has a small delay, called latency. For music, you do not notice it. For video, the picture and sound may drift apart a little, though most phones and laptops compensate for it. For fast games, the delay can be annoying.

If you plan to use the headphones with a TV or a console, check how they connect. Some TVs support Bluetooth headphones directly, and others need a transmitter. A wired connection removes the delay entirely, and both headphones can use a cable.

For serious gaming, many players choose a dedicated gaming headset with a low-delay wireless link or a cable. Our gaming gear guide has more.

Who should choose which

Sony tends to suit you if you

• like to adjust the sound and settings in an app
• want long battery life and fast charging
• use a phone that supports higher-quality codecs
• like touch controls and a modern minimal look

Bose tends to suit you if you

• value comfort over many hours above everything
• want simple physical buttons and a simple app
• prefer a smooth, easygoing sound without tweaking
• need headphones that fold flat in a bag

If both lists describe you, comfort usually breaks the tie. A pair that you forget you are wearing is a pair you will use.

Examples

A frequent flyer

The traveller needs strong noise cancelling, comfort for many hours and a compact case. Bose's folding design and soft fit are attractive, while Sony's longer battery claim helps on very long trips.

An office worker with an open-plan desk

Calls, focus and comfort matter most. Both do well. Multipoint switching between laptop and phone is a plus, and the choice may depend on which app and controls feel nicer.

A music lover

If you enjoy tuning your sound and use a phone with a high-quality codec, Sony gives you more to explore. If you want a relaxed, warm sound with no fiddling, Bose fits.

A student on a budget

Look at older models on sale from a trusted seller, or at cheaper noise-cancelling headphones. You may not need a flagship to get a calm study space.

How to try them properly

• Wear each pair for at least fifteen minutes, with glasses on if you wear them.
• Play music you know well, in a few styles, at a normal volume.
• Test the noise cancelling in a noisy place, if possible.
• Make a call and ask the other person how you sound.
• Use the controls without looking, and see which you prefer.
• Check the case and see if it fits your bag.
• Ask about returns, in case you do not get along with the fit.

Mistakes to avoid

• Choosing by brand alone. Comfort and fit are personal.
• Trusting battery claims as exact. Real life varies.
• Ignoring the warranty. A cheap import without service can cost more later.
• Expecting silence. Noise cancelling reduces sound, it does not remove all of it.
• Buying fake or copied products. Buy from official or trusted sellers, since fakes are common for popular headphones.
• Listening too loud. Noise cancelling helps you keep the volume lower, which is better for your ears.

Common questions

Which has better noise cancelling?

Both are excellent. Opinions differ by situation, and the gap is small. Comfort, features and your use matter more.

Which is better for calls?

Both are good. Results depend on your environment and call app. Test with a friend in your usual places.

Can I use them with a cable?

Yes, both support wired listening. Check the cable that comes in the box.

Are they good for the gym?

Not really. Over-ear headphones get warm and are not made for sweat. Choose sports earbuds for workouts.

Should I buy the newer models?

If you want the latest features and can afford it, maybe. If you want good value, an older model on sale can be a smart choice.
