Before You Start

  • Your pair of noise cancelling headphones (over-ear or in-ear buds).
  • A fully charged smartphone, tablet, or computer to pair them with.
  • Access to your device's app store (Apple App Store or Google Play Store).
  • The different sizes of ear tips that came with your headphones, if you have in-ear buds.
Check first: Never use noise cancelling headphones in situations where you must hear your surroundings for safety. This includes driving, cycling, or walking near busy traffic. Your hearing is a key part of staying safe and aware.

Step-by-Step Instructions

Achieve a Proper Physical Seal

Before you even turn them on, the most important step is getting a good physical fit. This creates a barrier called passive noise isolation, which is your first line of defense against noise. It works by simply blocking sound waves from reaching your eardrum.

For over-ear headphones: Adjust the headband so the earcups sit comfortably and completely enclose your ears. The cushions should create a gentle but complete seal against the side of your head. There should be no major gaps. If you wear glasses, you may need to adjust the arms to sit as close to your head as possible to minimize any gaps they create.

For in-ear headphones (earbuds): Your earbuds came with several sizes of silicone or foam tips. The ones installed by default may not be right for you. Try each size. The correct tip will slide in easily and expand slightly to fill your ear canal, feeling snug but not painful. When you have a good seal, outside sounds should immediately become more muffled, like you've put in earplugs.

Tip: To test the seal, talk out loud with the headphones on but powered off. Your voice should sound deeper and more "in your head." If it sounds normal, you likely don't have a complete seal.

Power On and Pair with Your Device

Next, let's connect the headphones to your phone or computer. Most modern headphones use Bluetooth for a wireless connection.

First, turn on your headphones. Usually, you'll need to press and hold the power button for a few seconds until you hear a sound or see a light flashing. This flashing light typically indicates they are in "pairing mode."

Then, on your phone or computer, open the Bluetooth settings. Make sure Bluetooth is turned on. You should see a list of available devices. Look for the model name of your headphones and tap on it to connect. Once paired, you'll usually hear a confirmation sound from the headphones, and the flashing light will turn solid.

Activate the Active Noise Cancellation (ANC)

This is where the magic happens. Active Noise Cancellation is an electronic feature that listens to outside noise and creates an opposite sound wave to cancel it out. It's incredibly effective against low-frequency, droning sounds.

You can usually turn ANC on in one of two ways. Most headphones have a dedicated button on one of the earcups. It might be labeled "ANC" or have an icon that looks like a sound wave. Pressing it will cycle through the different sound modes.

Alternatively, you may need to use the manufacturer's mobile app to activate it. When you turn on ANC, you should notice a dramatic reduction in ambient background noise, like the hum of an air conditioner or the rumble of traffic. It might feel like the world suddenly went quiet.

Understand the Different Sound Modes

Your headphones likely have more than just "On" and "Off." Understanding these modes lets you adapt to any situation.

  • Full ANC Mode: This provides the maximum level of noise cancellation. It's perfect for airplane travel, train commutes, or when you need deep focus.
  • Transparency Mode: Sometimes called "Ambient Aware" or "HearThru," this mode does the opposite of ANC. It uses the external microphones to intentionally let outside sound in. This is extremely useful for ordering coffee, listening for an announcement, or talking to a coworker without having to take your headphones off.
  • Off Mode: This deactivates all electronic processing. You'll only have the passive noise isolation from the physical seal. This is a good way to save battery life if you're in a relatively quiet environment.

Practice cycling through these modes using the button on your headphones to get a feel for how each one works.

Install and Explore the Companion App

To unlock the full potential of your headphones, you must download the manufacturer's free app from your phone's app store. Search for the brand name of your headphones (e.g., Sony, Bose, Anker) to find it. This app is the control center for all the advanced features.

Once installed and connected to your headphones, take a few minutes to look around. The app is where you can perform crucial tasks like updating the firmware (the software that runs on your headphones), which can improve performance and add new features. It's also where you'll find customization options that we'll cover in the next steps.

Customize Your Sound with the Equalizer (EQ)

Inside the companion app, you'll almost always find an equalizer, or "EQ." An EQ allows you to adjust the audio profile to match your personal taste. It lets you increase or decrease different frequency ranges, like bass, midrange, and treble.

Don't be intimidated by all the sliders. Most apps include several presets to get you started. You might see options like "Bass Boost" for more low-end punch in hip-hop, "Podcast" or "Vocal Boost" to make voices clearer, or "Treble Reducer" for a warmer, less harsh sound. Try these presets first while listening to your favorite type of audio. Once you're comfortable, you can try creating your own custom EQ setting by moving the individual sliders yourself.

Fine-Tune the ANC Level

Some advanced headphones don't just have one ANC mode; they let you adjust its strength. In the app, you might see a slider that lets you choose an ANC level from 1 to 10, or a setting that lets you focus the cancellation on specific sounds, like wind noise.

Why would you want less than maximum ANC? Some people are sensitive to the "cabin pressure" feeling that strong ANC can create. Lowering the level can make the experience more comfortable while still blocking a good amount of noise. You can also adjust it based on your environment—you might only need a little ANC in a quiet office but want the maximum setting on a loud bus.

Maintain Your Headphones for Long-Term Performance

A little care goes a long way. To keep your headphones working their best, follow a few simple maintenance habits.

  • Keep them clean. Regularly wipe down the earpads or ear tips with a dry, soft cloth. If ear tips get clogged with earwax, it can muffle the sound and reduce ANC effectiveness. Most silicone tips can be removed and washed gently with mild soap and water (be sure they are completely dry before reattaching).
  • Manage the battery. Active Noise Cancellation uses a lot of power. To maximize battery life, turn off your headphones when you're not using them instead of leaving them in standby mode. If you're in a quiet place, switch ANC off to conserve power.
  • Check for updates. Open the companion app every month or so to check for firmware updates. These free updates from the manufacturer can fix bugs, improve connection stability, and even enhance the noise cancellation algorithm.

Common Problems When You Use Noise Cancelling Headphones

I feel a weird pressure in my ears.

This is often described as "cabin pressure" or "eardrum suck" and is a known side effect for some users. It's caused by the way the ANC's "anti-noise" wave interacts with your eardrum. Your brain perceives the lack of low-frequency sound as a pressure change.

Solution: Try using a lower ANC setting in the companion app. If your headphones don't have adjustable levels, try taking short breaks every hour. Over time, many people get used to the sensation. If it remains very uncomfortable, you may be particularly sensitive to it.

The headphones aren't blocking people's voices.

This is expected behavior. ANC technology is designed to target constant, low-frequency sounds. It is much less effective against sharp, irregular, higher-frequency sounds like human speech, a baby crying, or a dog barking.

Solution: Manage your expectations. While ANC helps reduce the overall noise level, it won't create total silence. The passive isolation from a good physical seal is actually more important for blocking voices. Playing music or ambient sounds at a low volume will help mask the conversations ANC can't eliminate.

My battery dies really fast.

Active Noise Cancellation is an active process that requires significant power. The advertised battery life on the box is often for listening with ANC turned off. The real-world battery life with ANC on will always be lower.

Solution: Check the manufacturer's specifications for battery life with ANC enabled to see if your experience is normal. To extend the charge, turn ANC off when you're in a quiet environment. Using a wired connection instead of Bluetooth (if your headphones support it) can also save a small amount of power.

The sound is cutting out or stuttering.

This is almost always a Bluetooth connection issue. It can be caused by distance, physical obstructions (like walls or even your own body), or interference from other electronic devices.

Solution: Keep your audio source device (like your phone) close to your headphones. Try moving your phone from your back pocket to a jacket pocket. Turn off Bluetooth on other nearby devices you're not using. If the problem persists, try "forgetting" the headphones in your device's Bluetooth settings and then re-pairing them from scratch.

Advanced Tips for Noise Cancelling Headphones

Layer Your Silence

For the ultimate quiet zone, use your noise cancelling headphones in an already quiet space. The ANC will eliminate the subtle background hums you didn't even notice, like a refrigerator or computer fan, creating a profound level of silence that is perfect for deep focus, meditation, or reading.

Customize Your Controls

Dive into the companion app's settings. Many allow you to remap the physical buttons on your headphones. For example, if you never use the default voice assistant button, you might be able to change its function to cycle through your favorite EQ presets or adjust the ANC level directly, saving you from having to pull out your phone.

Master Multi-Point Pairing

If your headphones support "Bluetooth Multi-point," it's a game-changer. This feature allows you to connect to two devices at the same time, like your laptop and your phone. You can be listening to music from your laptop, and if a call comes in on your phone, the headphones will automatically switch over. Check your app or manual to learn the specific procedure for enabling this powerful feature.

Use Them for Better Calls

The microphones used for ANC are also great at isolating your voice during phone calls. They work to cancel out background noise around you, so the person on the other end can hear you more clearly. If you have an important call to take in a noisy environment, putting on your ANC headphones is a great idea.

Noise Cancelling Headphones FAQ

What's the difference between Active and Passive noise cancellation?

Passive Noise Cancellation (or noise isolation) is physical. It's the seal created by the earcup cushions or earbud tips that physically blocks sound from entering your ear. It's like a high-tech earplug. Active Noise Cancellation is electronic. It uses microphones to listen to incoming sound and then generates an opposite sound wave to neutralize it. The two work together for the best result.

Can noise cancelling headphones damage my hearing?

The technology itself is completely safe. In fact, it can help protect your hearing. By blocking out loud background noise, ANC allows you to listen to your music or podcasts at a much lower, safer volume than you would need with regular headphones. The primary cause of hearing damage from headphones is listening at excessively high volumes for long periods, which ANC helps you avoid.

Why do some people feel dizzy or nauseous using them?

This is an uncommon but documented side effect for a small number of people. It's thought to be related to how your brain and inner ear interpret the low-frequency sound information. The brain expects to hear certain ambient sounds, and when they are suddenly gone, it can cause a feeling of disorientation for some, similar to motion sickness. If you experience this, try a lower ANC setting or headphones known for a less aggressive effect.

Final Checklist for Noise Cancelling Headphones

  • Confirm you have a snug and complete physical seal on or in your ears.
  • Successfully pair the headphones to your primary device via Bluetooth.
  • Download and install the official companion app from the manufacturer.
