Choosing wireless headphones: how to avoid a disappointing purchase

A wireless headset may seem easy to choose at first glance. However, models vary considerably in comfort, battery life, sound isolation and call quality. A low price can be appealing, but an unsuitable fit, limited compatibility or disappointing battery life can quickly make everyday use inconvenient.

For music, films, podcasts and hands-free calls, these are the main pitfalls to watch out for:

• Battery claims without a clear testing method: “Up to 50 hours” often applies under specific conditions, such as noise cancelling being switched off and the volume set to a particular level.
• Noise cancelling that does not suit your needs: active noise cancellation works mainly against constant sounds, such as train or aeroplane engines. It does not replace complete sound isolation and may make surrounding sounds less audible.
• A fit that becomes irritating after a short time: in-ear headphones should seal well without creating pressure. An over-ear model can be comfortable, but may also feel warm or become too heavy during a long working day.
• Incomplete product information: always check whether the battery life refers to one earbud, the headphones themselves or the total including the charging case.

Which specifications are important?

1. Choose the right design first

Wireless earbuds and true wireless earbuds are compact and suitable for commuting, sport and everyday use. In-ear headphones generally provide a better seal, but choosing the right ear tip size is important. Some models come with several sizes of silicone ear tips.

Over-ear headphones cover the entire ear. This design is often practical for travelling, working from home and long listening sessions. An on-ear model, such as the Sony WH-CH520, is lighter and more compact, but lets in more ambient sound and rests directly on your ears.

For sport, a secure fit and a suitable IP rating are important. IPX5, for example, means protection against water jets according to the product specification, but does not automatically mean protection against immersion. Also check whether the charging case has the same protection as the earbuds.

2. Look beyond Bluetooth alone

Bluetooth 5.2, 5.3 or 5.4 mainly indicates the Bluetooth generation being used. The actual experience also depends on your phone, laptop, codec and software.

Look out for these features:

• Multipoint: connection to two devices, such as a laptop and smartphone.
• Microphones: important for headphones used for music and calls. More microphones can help with voice processing, but do not guarantee perfect conversations.
• USB-C: a common charging connection.
• Wired use: useful when the battery is empty or when using an aeroplane or laptop connection.
• App support: check whether the key functions also work without an app and which features are only available with Android or iOS.

3. Assess battery life realistically

Headphones with long battery life are useful for travelling and studying, but compare models under the same testing conditions. Noise cancelling, high volume, calls and codec use can affect battery life.

Also consider the charging time and fast-charging function. With earbuds, the charging case capacity also counts, while over-ear headphones usually quote one battery-life figure for the device itself. Also check whether a USB cable is included; many models do not come with a mains adapter.

Frequently asked questions about wireless headphones

How do I connect wireless headphones to my smartphone?

Switch on Bluetooth on your smartphone, open the Bluetooth settings and put the headphones into pairing mode. With many true wireless earbuds, this happens when you open the charging case. Then select the product name from the list. If the connection does not work, remove an old pairing and charge the headphones sufficiently.

How long do wireless headphones last?

Playback time per charge varies by model and settings. A battery loses capacity over time through charging and use. Do not store the headphones completely flat for long periods, avoid heat and use a suitable USB-C charger. Overall lifespan also depends on the hinges, ear cushions, charging contacts and software support.

Do Bluetooth headphones use a lot of power?

Bluetooth headphones generally use little power compared with a smartphone or laptop. Volume, active noise cancelling, calls and the codec being used have the greatest effect. However, a charging case or battery does need to be recharged regularly. Use a USB-C cable suitable for the device and follow the manufacturer's safety instructions.
