Choosing wireless noise-cancelling headphones: how to avoid a poor purchase

Wireless noise-cancelling headphones can be a great choice on the train, in the office or on a long flight. But a high decibel figure or long battery life doesn’t tell you everything. The fit, microphones and the way the manufacturer presents the specifications often determine whether you’ll keep using the product every day.

So, look out for these common pitfalls:

• A high ANC figure without context: a claim such as “up to 49 dB noise reduction” doesn’t tell you how effectively low rumbles, voices or wind are reduced. Performance also depends on the fit and your surroundings.
• Battery life without a clear distinction: check whether the stated listening time applies with ANC on or off. With earbuds, the charging case’s battery is also included in some figures, while over-ear headphones usually quote the headphones alone.
• An unsuitable design: in-ear models are compact, but not everyone finds earbuds comfortable. Over-ear headphones may be more comfortable for long listening sessions, but they’re heavier and less convenient to carry around.
• Misinterpreting water resistance: IPX4 or IP55 doesn’t mean you can submerge a product. Always check exactly what the IP rating means, and keep a charging case dry if it doesn’t have the same protection.

Which specifications matter?

1. ANC, transparency mode and fit

ANC, or active noise cancellation, uses microphones and electronic processing to counter background noise. The results vary from person to person. A well-sealed in-ear design can passively reduce noise, while an over-ear model with larger ear cushions offers a different wearing experience.

Look out for:

• multiple ANC modes;
• a transparency or ambient sound mode;
• replaceable or interchangeable ear tips;
• an app for sound settings;
• multipoint, so you can connect, for example, a laptop and phone.

A pair of wireless noise-cancelling earbuds is particularly practical for commuting and calls. For a relaxed listening session at home or in the office, over-ear headphones may be more comfortable to wear.

2. Battery life in practice

Don’t just look at “up to” a certain number of hours. Check whether ANC is on, whether the figure applies to each earbud, and whether it includes the charging case. Headphones with long battery life are useful for travelling, but fast charging can be just as important.

Examples from product specifications:

• The Soundcore A30i states 7 hours of listening per charge and up to 24 hours with the charging case.
• The CMF by Nothing Headphone Pro states up to 100 hours without ANC and 48 hours with ANC.
• The Sony WF-C710N states up to 30 hours with noise cancelling and 40 hours without, according to the product information.
• The OnePlus Buds Pro 3 states up to 12 hours per charge and up to 44 hours with the case.

These figures are taken from product descriptions. Actual battery life may vary depending on volume, codec, connection and ANC settings.

3. Calls, codecs and connectivity

If you’re looking for wireless earbuds for calls and music, it’s worth checking the number of microphones and the connection options. More microphones may help with voice capture, but they don’t guarantee clear calls in strong winds.

Also look out for:

• Bluetooth version: a recent version can help provide a stable connection, but compatibility with your phone and laptop is still important.
• Multipoint: useful when switching between your work computer and smartphone.
• Audio codecs: AAC, SBC, LDAC and LHDC aren’t supported by every device.
• USB-C and fast charging: handy when you’re short on time while out and about.
• Controls: physical buttons can be more reliable when wearing gloves; touch controls are compact and quick to use.

Frequently asked questions about wireless noise-cancelling headphones

How do I set up ANC properly?

Start by choosing the right ear tip size or adjusting the headband so the ear cushions fit snugly. Then select an ANC mode in the app or using the controls. Use transparency mode in traffic or anywhere you need to hear the sounds around you.

How long do wireless headphones last?

Battery life per charge depends on volume, ANC, Bluetooth codec and calls. The overall lifespan is also affected by the built-in battery. Keep your headphones dry, charge them according to the instructions and avoid prolonged exposure to heat. Statutory EU consumer guarantees are separate from normal battery wear.

Does ANC use a lot of battery?

Active noise cancellation uses extra electronics and can reduce battery life. So always check the separate figures for ANC on and off. If you mainly listen at home, you can switch ANC off to listen for longer; when you’re out and about, the feature is more useful. Don’t listen at high volume for long periods, and don’t use headphones while cycling, driving or in other situations where you need to stay aware of your surroundings.
