Noise Cancelling Headphones

Active noise cancelling (ANC) headphones block the steady hum of engines, fans, and office chatter so you can focus or relax. This guide shows you how to choose, set up, and get the best sound from your first pair. The main caution is to manage your expectations: noise cancelling reduces constant noise well but does not completely silence loud, sudden sounds.

Fast Answer

Choose ANC type: Over-ear for best blocking; in-ear for portability
Set expectations: Kills hums, not shouts

Beginner Difficulty

Pressure feel Watch out for

Before You Start

A smartphone, tablet, or computer with Bluetooth for wireless pairing
The charging cable that comes with your headphones (usually USB-C)
The companion app for your headphone brand, if one exists
Your music, podcast, or white-noise source ready for testing
A quiet room to test the basic controls before you go outside

Check first: Read the safety notes in the box. Some people feel a slight pressure in their ears when ANC is on. If you feel dizzy or uncomfortable, turn ANC off and take a break.

Step-by-Step Instructions

Pick the Right Style for Your Use

Choose over-ear headphones if you want the strongest noise blocking and plan to wear them for long flights or whole work sessions. The large pads surround your ears and create a physical seal that works with the electronics.

Choose in-ear models (sometimes called earbuds) if you want something small for the gym, commuting, or travel. They block less noise but slip into a pocket easily. Match the style to your main activity: over-ear for desks and flights, in-ear for movement and portability.

Tip: If you wear glasses, try over-ear pads with soft cushioning so the arms of your glasses do not press into your head.

Charge Before First Use

Plug the included cable into the headphones and a USB power source. Most models need a full charge before you set them up. This takes about 2 to 3 hours for a full battery.

Check the manual for the charging light colour. It usually turns from red to green or blue when full. Do not use a fast phone charger unless the manual says it is safe; standard charging is fine overnight.

Tip: Charge your ANC headphones overnight before a long trip. Many models give you 20 to 30 hours of listening per charge.

Pair With Your Phone or Computer

Turn on Bluetooth on your device. Hold the power button on your headphones until the light blinks blue and red (or says "pairing" in your ear).

Open the Bluetooth settings on your device and tap the name of your headphones when it appears. You should hear a chime or see "Connected" on the screen. Repeat this process for each new device you want to use.

Tip: Name your headphones something clear in the Bluetooth settings, like "Office ANC" or "Travel Buds," so you know which pair you are connecting to.

Download the Companion App

Visit the app store on your phone and search for the brand name of your headphones. Install the official app. This is where you control the noise cancelling level, adjust the equaliser, and update the firmware.

Open the app and follow the setup screen. It may ask for permission to see your location or Bluetooth connections; allow it so the app can find your headphones. The app is free and usually works for all models from that brand.

Tip: Firmware updates sometimes improve noise cancelling strength. Check the app once a month for updates.

Turn On Noise Cancelling

Find the ANC button on the ear cup or stem. It often has a small wave icon or says "NC." Press it once to cycle through modes: ANC on, ANC off, and transparency or "ambient" mode.

Press until you hear or feel the seal close around you. You should notice a drop in background hum. If you do not notice a change, check the app to confirm ANC is active.

Tip: Test ANC with a fan or air conditioner running. The steady hum should almost disappear.

Adjust the Fit for Better Blocking

Move the ear cups so they cover your ears completely. The band should rest lightly on your head, not squeeze. A good seal is the most important part of noise cancelling; gaps let sound leak in.

For in-ear models, twist the tips into your ear canal until you feel a snug fit. Try the different silicone tip sizes in the box; the right size makes a big difference to bass and blocking.

Tip: The best test is to play a quiet song and walk around. If the sound stays steady, the fit is good.

Learn the Basic Controls

Find the buttons or touch surfaces on the ear cups. Common controls are: one tap to play or pause, two taps to skip forward, three taps to go back. Press and hold to adjust volume or change modes.

Test each control while music plays so you do not have to fumble later. Write down the controls for your model in the notes app of your phone for quick reference.

Tip: Many models let you pause music automatically when you take the headphones off. Check the app for this setting.

Set the Volume at a Safe Level

Start music at 50% volume and adjust up slowly. ANC lets you hear music clearly at lower volumes, which is healthier for your ears. If you keep raising the volume to hear, the ANC may not be working well.

Do not exceed 70% volume for long listening sessions. That is loud enough to damage hearing over time. Use the app's volume limiter if your model has one.

Tip: In a very loud place like a plane, ANC at a higher setting with music at 60% is safer for your ears than turning the music up to drown the noise.

Test Transparency or Ambient Mode

Switch to transparency mode when you need to hear people talking, announcements, or traffic. This mode uses microphones to let outside sound in. It is useful in airports or when walking on busy streets.

Speaking with ANC on can make your voice sound muffled to you. Use transparency mode during phone calls or when ordering coffee to hear yourself clearly.

Tip: Set a shortcut on the ear cup to switch between ANC and transparency quickly, so you can react fast in conversations.

Quick Reference

Situation	Use this	Why
Long flight or train	Full ANC, over-ear	Blocks engine and track rumble for hours
Walking on a city street	Transparency mode	Hear traffic and people around you
Open office with chatter	ANC with soft music	Masks voices better than silence
Phone call in a cafe	Transparency mode on	Hear your own voice clearly
Gym or short commute	In-ear with ANC	Light weight and stays in place

Common Problems When You Use Noise Cancelling Headphones

ANC does not seem to work: Check the app to confirm ANC is on. If it still does not block, the fit may be loose. Re-adjust the ear cups or try a different silicone tip size for in-ear models.
A hissing sound in quiet rooms: This is normal. ANC microphones create a faint hiss when there is no noise to cancel. Play very quiet music or white noise to mask it.
Ear pressure or dizziness: Some people feel a "vacuum" effect. Turn ANC off for 15 minutes and try again. If it keeps happening, use transparency mode instead of full ANC.
Headphones keep disconnecting: Move closer to your device and close other apps that use Bluetooth. Forget the device in Bluetooth settings and pair again.
Battery drains fast: ANC uses more power than normal mode. Turn off ANC when you do not need it and lower the volume. Check the app for battery-saving settings.
Sound is muffled or quiet: Check that no earwax or debris is blocking the speaker mesh. Clean the ear tips or pads gently with a dry cloth.

Advanced Tips for Noise Cancelling Headphones

Use ANC for focus, not just travel. Many people use ANC at home to block the washing machine, road noise, or neighbours. Play brown noise or rain sounds at a low volume to create a calm bubble for deep work.

Learn the "talking through" trick. Some models let you place your hand over the ear cup to temporarily lower the volume and let in outside sound. This works better than taking the headphones off every time someone speaks to you.

Customise the equaliser in the app. You can boost voices in podcasts or add bass for music. Save different presets for music, calls, and quiet focus sessions.

Use one earbud in quiet settings. If you only need a little help concentrating, wear one earbud with ANC on and leave the other ear free. This saves battery and keeps you aware of your surroundings.

Keep the firmware updated. Manufacturers improve ANC algorithms over time. An update can make a pair sound noticeably better than the day you bought them.

Noise Cancelling Headphones FAQ

Common Issues

If the result is not working as expected, return to the previous step, check the material or setting involved, and make one adjustment at a time for noise cancelling headphones.

Do noise cancelling headphones block all sound?

No. ANC is best at reducing steady, low-frequency sounds like engines, fans, and air conditioners. It does not block sudden, loud, or high-pitched sounds like alarms, clapping, or crying babies. The physical seal of the ear cups helps with mid-range sounds too, but nothing cancels everything.

Can I use ANC headphones without music?

Yes. You can turn on ANC with no audio playing. This is useful for studying, sleeping on a plane, or reducing noise sensitivity. The headphones will still use battery, but you will get a quieter space.

Are ANC headphones safe for children?

Yes, but set the volume low and limit listening time. ANC can reduce the need for high volume. Check the app for a volume limiter and show younger children how to keep the volume under 60%.

Do I need ANC if I already have regular headphones?

It depends. If you are bothered by constant noise like traffic, fans, or office HVAC, ANC is a clear upgrade. If you only listen in quiet rooms, regular headphones are fine. The ANC is most valuable in places with a steady hum.

How long do ANC headphones last?

Battery life varies from 20 to 60 hours per charge depending on the model and volume. The headphones themselves should last several years if you keep them clean and store them in the case. Replaceable ear pads are available for most models.
