Choosing noise-cancelling headphones: what should you look for before buying?

Noise-cancelling headphones can make a train journey more peaceful, improve conversations while working from home and bring out more detail in your music. However, comparing models fairly can be difficult. Manufacturers use different testing methods, battery claims do not always apply with active noise cancellation switched on, and a comfortable fit varies from person to person.

So focus on the specifications that make the biggest difference in everyday use. This helps you avoid paying mainly for marketing terms you are unlikely to use.

Common pitfalls when choosing noise-cancelling headphones

1. A high decibel figure does not tell you everything

Some models, for example, advertise noise cancellation of “up to -44 dB” or “up to -45 dB”. This is a product specification measured under certain conditions, not a universal benchmark. Low-frequency sounds, such as train noise, are often handled differently from voices or sudden sounds.

So also compare:

  • Whether the ANC function is adaptive.
  • Whether a transparency mode is available.
  • Whether you can adjust the level of noise cancellation.
  • How effectively the ear cushions passively block out surrounding noise.

2. Battery life without ANC can give a misleading impression

Headphones with 80 or 100 hours of battery life sound appealing. This often refers to use without active noise cancellation. With ANC, higher volumes and Bluetooth functions enabled, actual battery life may be lower.

So check the battery life specifically with ANC switched on. A fast-charging function is also useful: charging for a few minutes may be enough for a commute or an online meeting.

3. Lightweight headphones are not automatically comfortable

Weight is important, but it is not the only criterion for comfortable headphones. The pressure from the headband, the depth of the ear cushions, heat build-up and adjustability all determine whether you can wear them for hours.

A model that is light on paper can still feel uncomfortable if the headband is too tight. Also check whether the ear cushions can be replaced. This can extend the lifespan of wireless headphones.

Important specifications to compare

ANC and ambient modes

ANC headphones use microphones to detect and counteract surrounding noise. This is generally more relevant for aeroplanes, trains and fans than for short, high-pitched sounds. A transparency mode lets surrounding sounds through again when you are having a conversation or walking outdoors.

Do not use ANC as a substitute for staying alert. Headphones are not suitable when cycling, driving or carrying out activities where you need to hear your surroundings.

Bluetooth, codecs and multipoint

Bluetooth 5.2, 5.3 or 5.4 mainly indicates the connection standard; it does not automatically provide information about sound quality. Also check which codecs are supported:

  • SBC and AAC: commonly used codecs for phones and laptops.
  • LDAC: according to the product specification, suitable for higher data transfer rates, but your source device must support it too.
  • aptX Lossless: only usable with compatible devices and content.
  • Multipoint: allows you to connect to two devices at the same time, such as a laptop and smartphone.

If you are looking for headphones for music and calls, also pay attention to the number of microphones, wind-noise reduction and the controls for calls. A wired option is useful when the battery is empty or when you are using a source without Bluetooth.

Battery, charging and wired use

Always compare:

  1. Battery life with ANC switched on.
  2. Battery life with ANC switched off.
  3. Charging time and fast-charging function.
  4. USB-C connection.
  5. Option to listen using a cable.

Long battery life makes headphones more practical for travelling, but also check whether a charger is included. Some models only come with a USB cable. The legal guarantee in the EU for the products mentioned is at least two years; check the current terms and conditions on the product page.

Frequently asked questions about noise-cancelling headphones

Do noise-cancelling headphones work without Bluetooth?

Yes. Several models support a wired connection via 3.5mm, USB-C or a supplied audio cable. Check whether ANC continues to work in wired mode and whether the battery needs to be charged for this.

How long do wireless headphones last?

Lifespan depends on the battery, hinges, ear cushions and daily use. A model with replaceable ear cushions is easier to maintain. Store the headphones in a dry place, charge them using a suitable USB source and avoid prolonged use at maximum volume.

Does ANC cost more to run?

The electricity costs of charging are generally limited. The main recurring costs are more likely to come from replacing the ear cushions or the headphones themselves when the battery loses capacity over time. So do not look only at the purchase price; also consider repair and replacement options.
