Whether it's a noisy train, an open-plan office or a long flight, noise cancelling headphones can make everyday sound far more pleasant. They also let you listen at lower volumes because you're not competing with background noise. This guide explains how noise cancelling works, the difference between headphones and earbuds, and the features to compare.
How active noise cancelling works
Active noise cancelling (ANC) uses small microphones to listen to the sound around you. The headphones then create an opposite sound wave that cancels much of that noise before it reaches your ears.
ANC is most effective on steady, low-frequency noise such as engine hum, air conditioning and road rumble. It's less effective on sudden or higher-pitched sounds such as voices or clattering dishes. That's where passive isolation, the physical seal of the ear cushions or ear tips, does most of the work. The best results come from good ANC combined with a good fit.
Over-ear headphones vs earbuds
| Over-ear headphones | True wireless earbuds | |
|---|---|---|
| Comfort | Spread pressure around the ear; can feel warm in summer | Very light, but some people find them tiring over long periods |
| Noise reduction | Larger cushions often add stronger passive isolation | Depends heavily on a good ear-tip seal |
| Battery | Typically longer per charge | Shorter per charge, topped up by the charging case |
| Portability | Bulkier, usually fold into a case | Pocket-sized |
| Best for | Flights, long commutes, working from home | Gym, walking, everyday carry |
Many people end up owning both: earbuds for daily use and over-ear headphones for travel and focus time.
Features worth comparing
Transparency or ambient mode
This mode uses the microphones to let outside sound in, so you can hear announcements, traffic or a colleague without removing your headphones. It's important for safety when walking near roads.
Call quality
If you take a lot of calls, look for models with multiple beam-forming microphones and wind noise reduction. Reviews and product descriptions usually note call performance.
Battery life and charging
Check the battery life with ANC switched on, as that's how you'll mostly use them. Quick-charge features that give hours of playback from a short charge are handy for travel. A compact power bank helps keep headphones and phones running on long trips.
Multipoint connection
Multipoint lets the headphones stay connected to two devices at once, such as a laptop and phone, and switch automatically when a call comes in.
Codecs and app support
Bluetooth codecs affect audio quality and latency. Some brands support higher-quality codecs that work best with matching phones. A companion app usually lets you adjust EQ, ANC levels and controls, and install firmware updates.
Fit and comfort
For over-ear models, look at headband padding, weight and cushion depth. For earbuds, check that multiple ear-tip sizes are included and consider the shape if you have smaller ears.
Matching headphones to how you'll use them
- Commuting and travel: Strong ANC, long battery and a compact case.
- Working from home or in the office: Comfort for long periods, good microphones and multipoint.
- Exercise: Secure-fitting earbuds with sweat and water resistance. Keep transparency mode on near traffic.
- Gaming: Low latency matters. A wired or 2.4GHz wireless gaming headset with a boom microphone is often a better match than Bluetooth headphones.
- Kids: Look for models with volume limiting and a comfortable, adjustable fit.
Looking after your hearing
Noise cancelling can help you listen at lower volumes, but it's still wise to keep the volume moderate and take breaks. Many phones include settings that warn you about loud listening levels. For noisy work such as using power tools, use proper hearing protection rather than consumer headphones; our hearing protection guide covers suitable options.
Wired, Bluetooth or both?
Most noise cancelling headphones are wireless, but some over-ear models also include a 3.5mm cable. That's useful on planes with in-seat entertainment, or if the battery runs flat, as many models still play passively when wired. Earbuds rarely include a wired option, so check battery life and case charging carefully if you travel a lot.
USB-C charging is now standard on most models, which means one cable can often charge your headphones, phone and tablet. Some charging cases also support wireless charging pads.
Questions to ask before you buy
- Where will you use them most: on public transport, at a desk, on flights or at the gym?
- Do you prefer the feel of over-ear cushions or the lightness of earbuds?
- How important is call quality compared with music quality?
- Do you need to connect to two devices at once?
- Will you wear them in hot weather, where lighter designs are more comfortable?
Answering these narrows the choice quickly, so you can focus on comfort and fit, which are the factors that decide whether you'll actually wear them every day.
Caring for your headphones
- Wipe ear cushions and tips regularly, and replace tips if they lose their seal.
- Store over-ear headphones in their case to protect the headband and hinges.
- Keep earbud charging contacts clean and dry.
- Install firmware updates through the companion app.

Frequently asked questions
Do noise cancelling headphones block all sound?
No. ANC greatly reduces steady low-frequency noise, but voices and sudden sounds will still come through, softened by the passive seal.
Are over-ear headphones better at noise cancelling than earbuds?
Over-ear models often block more noise because the cushions add passive isolation, but well-fitting earbuds with good ANC can come close.
Can I use noise cancelling headphones for gaming?
You can, but Bluetooth can add a small delay. For competitive gaming, a wired or low-latency wireless gaming headset is usually a better choice.
Is it safe to wear noise cancelling earbuds while walking or running?
Use transparency or ambient mode near roads so you can hear traffic, and keep the volume at a level where you remain aware of your surroundings.
