Audio Comparisons and Buying Guide

Start here

Good sound is one of the few things in technology that you notice every single day. You hear it in the morning commute, in video calls at work, in the film you watch at night and in the music you play while you cook. A product that sounds right makes ordinary moments nicer. One that sounds wrong becomes a small daily irritation.

The trouble is that audio shopping is full of confusing words, bold claims and numbers that mean little on their own. This page tries to cut through that. It explains what actually matters in headphones, earbuds, speakers, soundbars and studio gear, and it sends you to our detailed comparisons when you are ready for them.

A word about how we work. Our guides use published specifications, official documents and public information. We do not claim to have conduct controlled measurements, and we do not make up sound charts or scores. Since sound is personal, we also try to say clearly which parts are fact and which are taste.

Begin with how you listen

Before you look at a single product, answer these questions.

• Where will you listen most: on the move, at a desk, at home on the sofa or in a studio?
• Will it be music, calls, films, games, podcasts or a mix?
• Do you need to block the outside world, or hear it?
• Do you listen alone, or does the sound need to fill a room?
• How long do you listen in one go?
• What is your phone or computer, and what does it support?

The answers decide the type of product long before they decide the brand. A person who listens on trains needs different things from someone who works in a quiet home office. Someone who watches films with the family needs a soundbar, not headphones.

Headphones and earbuds

This is the biggest group, so it helps to know the main designs.

If you travel or work in noisy places, noise cancelling headphones are the most life-changing choice. We compare two famous ones in Sony WH-1000XM5 vs Bose QuietComfort 45. If you prefer earbuds, our AirPods vs Sony guide explains how the two big names differ. For a wider view, read the headphone and earbud guide.

Noise cancelling, explained

Active noise cancelling uses microphones to listen to the sounds around you, then creates an opposite sound to cancel them. It works best on steady, low noise like engines, fans and air conditioners. It works less well on sudden sounds and voices.

There is also passive isolation, which is simply the physical block that the ear cups or ear tips create. A good fit blocks a surprising amount of noise even without any electronics. If your earbuds or headphones do not fit well, cancelling will not work as it should.

Two practical notes. Noise cancelling lets you listen at a lower volume, which is kinder to your ears. And some people feel a mild pressure from it, so it is worth trying before you commit.

Wireless audio and codecs

Most headphones now connect by Bluetooth. Wireless is convenient, but it compresses the sound, and the way it does so is called a codec. The codec has to be supported by both your headphones and your phone or computer.

• SBC is the basic codec that every Bluetooth device supports.
• AAC is common on Apple devices and works well with them.
• aptX and its variants are found on many Android phones and headphones, with low delay and good quality.
• LDAC is a higher-bitrate codec from Sony, supported by many Android phones.
• LE Audio and LC3 are newer standards that aim at better efficiency and quality, and they are growing in support.

For casual listening, the differences are small, and a good pair of headphones with a standard codec sounds very good. If you care about quality, check that your phone and your headphones share a better codec. Our wireless technology guide explains more, including range and stability.

Delay is another point. For music, a slight delay does not matter. For video and games, it can. Wired connections have no delay at all.

Wired headphones and why they still matter

Wireless is not always better. Wired headphones need no battery, never drop their connection and often give more sound quality for the price. They are a great choice for a desk, for a studio or for anyone who wants to plug in and forget.

Two numbers appear in the specifications. Impedance, in ohms, tells you how hard the headphones are to drive. Low-impedance models work well straight from a phone. High-impedance models may need an amplifier. Sensitivity shows how loud they get for a given power. If your device has no headphone jack, a small USB-C adapter with a built-in converter often solves it.

Do not expect a big jump in quality from an expensive cable. A good basic cable is enough. The headphones themselves matter far more.

Portable and home speakers

A Bluetooth speaker fills a room, a garden or a picnic with sound. When you choose one, think about where it will be used.

• Size and sound. Bigger speakers usually sound fuller and have more bass. Small ones are easy to carry but limited.
• Battery. Check the claimed hours and how loud the speaker plays at that level.
• Water and dust protection. A rating such as IP67 means strong protection against dust and water, which is good for beaches and rainy trips. The rating does not make it indestructible.
• Pairing. Many speakers can link in pairs for stereo, or in groups for a larger sound.
• Microphone. Useful for calls, but not a replacement for a headset.

For home use, a pair of small powered speakers on a desk can sound much better than a laptop alone. For a larger room, a single speaker rarely fills the space as well as two placed apart.

Soundbars and home cinema

Thin TVs have thin speakers, and dialogue often sounds weak. A soundbar is the simplest fix. It sits under the TV, connects with one cable and gives clearer speech and fuller sound.

Main things to look for:

• Connection. An HDMI ARC or eARC port gives the best link to a modern TV. An optical cable is a fallback.
• Channels. A number like 2.1 means two speakers and a subwoofer. Higher numbers add centre and height channels for a wider effect.
• Subwoofer. A separate one adds deep bass, but it takes space. A built-in bass speaker is easier to place.
• Surround and height effects. Formats such as Dolby Atmos can add a sense of height, but the effect depends on the room and the content.
• Dialogue modes. A speech enhancing mode helps with mumbled voices.

Our soundbar comparison looks at three popular names in detail. If you want a full home cinema with separate speakers and a receiver, expect more cost, more cables and a bigger improvement, with careful placement.

Studio monitors and creative audio

If you make music, record podcasts or edit video, you need to hear the sound as it really is. Studio monitors are speakers designed for that. Instead of making music sound pleasant, they try to be neutral, so that what you hear matches what the recording contains.

Most are active, which means the amplifier is built in. Common sizes range from small 4 or 5 inch models for desks to 8 inch models for larger rooms. Place them at ear height, with the tweeters facing you and forming a triangle with your head.

The room matters as much as the speakers. A small bare room causes echo and uneven bass, which can mislead you. Simple acoustic panels and a rug can help a lot. Read our studio monitor comparison for details, and if you are recording voices, see our podcast and streaming guide.

Microphones

If you speak to an audience, whether on calls or recordings, a proper microphone gives a clear step up over a built-in one. There are two main types.

A dynamic microphone is tough, handles loud sounds and ignores much of the background noise. It suits untreated rooms and is popular for podcasts and streaming. A condenser microphone is more sensitive and picks up fine detail, which is good in a quiet, treated space but can also pick up keyboard noise and room echo.

For connections, a USB microphone plugs straight into a computer and is the easiest start. An XLR microphone needs an audio interface but offers more flexibility and better upgrade paths.

Whatever you choose, position matters. Speak close to the microphone, a few fingers away, and slightly off to the side to reduce harsh puffs of air. A pop filter helps too.

Sound quality: what to trust

Sound is partly physics and partly taste. Some things can be measured, and others are personal.

Measurable things include frequency response, which shows how evenly the product plays low, mid and high sounds, and distortion. These give hints, but they depend on how and where they are measured, so numbers from different sources are hard to compare.

Personal things include how much bass you like, how bright you want the treble and whether you prefer a warm or an analytical sound. Two people can listen to the same headphones and describe them very differently.

Be careful with big claims. Terms like "studio quality", "hi-res" and "audiophile" are often marketing words. A high number of watts or drivers does not make a better sound. The best approach is to listen to music you know well, at a normal volume, in a place like your usual setting.

For more about numbers and how to read them, see our page on measurement standards.

Protecting your hearing

Hearing damage is gradual and permanent, so prevention matters. Loud sound over a long time harms the tiny hair cells inside the ear, and they do not grow back.

• Keep the volume moderate, so that you can still hear someone talking next to you.
• Take breaks during long sessions. Give your ears a rest every hour or so.
• Use noise cancelling or well-fitting earbuds in noisy places, so that you do not turn the volume up.
• Use the volume warning features that many phones offer.
• Wear ear protection at concerts and when using loud tools.
• If you notice ringing or muffled hearing, rest and speak to a doctor.

These are general tips and not medical advice. If you have any concerns about your hearing, see a professional.

Your room changes the sound

People spend a lot on speakers and forget the room. The room is half of what you hear. Hard, bare surfaces such as tile, glass and plain walls reflect sound and cause echo and harshness. Soft items such as rugs, curtains, bookshelves and sofas absorb it and make the sound calmer.

A few simple steps help. Put a rug on a hard floor. Add curtains or a bookshelf on a bare wall. Keep speakers away from corners, which boost bass in a boomy way, unless the maker advises otherwise. Place them at ear height and aim them at the listening spot.

These changes cost little and often improve the sound more than an expensive upgrade. If a soundbar's subwoofer rattles the room, move it, or turn the bass level down a notch.

Watching TV without disturbing others

Many households have a problem: someone wants to watch late, and someone else wants to sleep. There are a few good answers.

Wireless headphones that pair with the TV are one. Some TVs support Bluetooth directly, while others need a transmitter plugged into an audio output. Check the delay, since a long one makes speech look out of step with lips. A wired connection removes the problem if the cable can reach.

A soundbar with a night mode is another. It reduces loud bass and sudden peaks, so that explosions do not wake the house, and it keeps dialogue clear. Speech boost features also help you keep the volume lower.

For shared listening, some systems let two pairs of headphones connect at once, so that two people can watch together in silence.

Audio for calls, gaming and streaming

Calls

For clear calls, microphone quality matters most. A headset with a boom microphone close to your mouth often beats a pricey headphone with a distant microphone. Earbuds have improved a lot, but wind and noisy streets still challenge them. Test with a friend before you rely on them for work.

Gaming

Gamers need low delay, a good microphone and comfort for long sessions. A wired headset is the safest for competitive play. Wireless gaming headsets with their own USB receiver can have very low delay, while ordinary Bluetooth is usually slower. See our gaming gear guide.

Streaming and podcasts

A dynamic USB microphone, closed-back headphones to avoid sound leaking into the mic, and a quiet room are a strong, simple start. Record some test clips and listen back, since your ears hear differently when you are speaking.

Children and shared listening

Children's ears are still developing, and they often listen at loud levels without realising it. If you buy headphones for a child, look for models with a volume limit, and check that the limit is truly effective, since some are not very strict. Choose comfortable ones that fit their head size.

Set limits together, and explain why. Short sessions and regular breaks are good habits. For young children, speakers or shared listening at low volume can be a better choice than headphones.

The same ideas apply to older relatives who like to listen loudly. Subtitles, a soundbar with a speech mode or headphones with a clear voice setting can help without having to turn up the volume.

Buying second-hand audio gear

Used audio equipment can be a bargain, especially headphones and studio gear that are built to last. But there are traps.

• Wireless earbuds and headphones have batteries that wear out. Ask how old they are and test the battery.
• Ear pads and tips wear out and can be replaced, but check that replacements exist.
• Test both sides for sound, and listen for crackling, distortion and imbalance.
• Check controls, buttons, ports and the app connection.
• Be careful with fakes, which are common for popular models. Compare the packaging and serial number with the maker's information.
• Ask whether the earbuds are linked to someone else's account, which can stop you from using them.

For hygiene, replace pads and tips on used in-ear and over-ear products, and clean them well.

Buying well

• Pick the type of product first, then compare models.
• Try before you buy if you can, with music you know well.
• Check that your phone or TV supports the connections you need.
• Read independent reviews for the exact model, not just the brand.
• Check the warranty and who handles repairs in your country.
• Be careful with fakes. Popular headphones and speakers are heavily copied, so buy from official or trusted sellers.
• Check the return policy, since fit and comfort are personal.

Prices and models change quickly, which is why we do not print price lists. Compare the real price from a few sellers on the day you buy.

Looking after your gear

Audio equipment lasts longer with a little care. Store headphones and earbuds in their case. Wipe ear pads and tips with a slightly damp cloth, and let them dry. Keep earbud mesh clean with a dry soft brush. Do not wind cables tightly or pull on them.

For wireless gear, do not let the battery sit at zero for long periods, and avoid leaving it in a hot car. For speakers, keep ports and grilles dust-free, and do not push them to maximum volume all the time, since distortion can damage the drivers.

Update the firmware when the maker releases a new version. It can fix bugs and add features.

Mistakes to avoid

• Buying by brand and price alone. Fit, comfort and use matter more.
• Ignoring fit. A poor fit ruins both sound and cancelling.
• Trusting big numbers. Watts, drivers and hertz claims are not proof of quality.
• Forgetting your devices. Check codecs, ports and compatibility.
• Listening too loud. Your ears cannot be replaced.
• Buying fakes. A deal that looks too good often is.

Common questions

Are wireless headphones as good as wired?

Many sound very good, and the difference is small for casual listening. Wired ones still win for zero delay, no battery and often better value.

Do I need noise cancelling?

If you travel or work in noisy places, it is one of the best upgrades you can make. In a quiet room, it matters less.

Is a soundbar worth it?

For most TVs, yes. It improves speech and adds fullness with little effort. Check the connection types first.

What is better: headphones or speakers?

It depends on the place. Headphones give private, detailed sound. Speakers share it with the room.

Where should I start?

Choose the situation that matters most to you, read the matching guide on this page, and compare two or three models.
