Choosing wireless Bluetooth headphones: specifications and pitfalls to look out for

A wireless Bluetooth headset can seem suitable for music, calls, travel or sport at first glance. However, models vary considerably in comfort, battery life and protection against moisture. A low price also says little about the user experience if the fit is poor or the microphone struggles in a busy environment.

The following three pitfalls are common:

• “Long battery life” without clear testing conditions: playback time can vary when noise cancelling, high volume levels or phone calls are used.
• Misinterpreting water resistance: IPX4 and IPX5 do not guarantee that headphones are suitable for submersion or swimming.
• Choosing a design that does not suit how you use it: over-ear headphones are comfortable on the train but can feel too warm when running. Open-ear headphones let you hear your surroundings, but do less to block out noise.

Which specifications should you check?

1. Wearing style and fit

First, choose between an over-ear, on-ear, in-ear or open-ear design.

• Over-ear: surrounds the ear and is often suitable for travelling, working from home and longer listening sessions. A model such as the Sony ULT WEAR weighs 255 grams according to the product information and has a foldable design.
• On-ear: rests on the ear and is usually compact and lightweight. The Sony WH-CH520 weighs 147 grams according to the product specifications.
• Ear hook or clip-on: stays in place more securely while you are moving. The Soundcore AeroFit Pro uses an ear hook and weighs 88.74 grams according to the product description.
• Open-ear: allows surrounding sounds through. This can be practical when walking or exercising, but is less suitable in places where you specifically want to block out noise.

Do not just consider the weight. Also check whether the headband is adjustable, whether the ear cushions are soft and whether an ear hook puts pressure on your ear.

2. Bluetooth, connection and multipoint

A Bluetooth version such as Bluetooth 5.2 or 5.3 provides information about the connection technology used, but does not by itself indicate how stable the connection will be in every home or on every train. Walls, other devices and distance all affect the result.

Multipoint is useful for the office and working from home. According to the product description, it allows headphones to connect to two devices, such as a laptop and smartphone. The Sony WH-CH520 and Sony ULT WEAR list this feature.

Also check codec support. AAC, SBC and LDAC partly determine how audio is transmitted, but the final quality also depends on your smartphone, streaming service and settings.

3. Battery life, microphone and protection

Compare battery life on a like-for-like basis. Some specifications state the maximum playback time without active features, while others provide a separate figure for use with noise cancelling. For example, the Sony ULT WEAR lists up to 30 hours with noise cancelling and up to 50 hours as its general battery life, according to the product specifications.

For calls, you need headphones with a microphone, but the number of microphones is not the only factor. Wind, traffic and the position of the microphone affect how clearly you can be heard. Claims about noise reduction should be treated as information from the product description or based on the brand’s own testing, rather than a guarantee for every environment.

An IP rating is important for sport:

• IPX4: protection against splashing water, such as sweat or light rain.
• IPX5: protection against water jets from different directions.
• No IP rating does not automatically mean that the product is vulnerable, but there is no clearly stated level of protection to use for comparison.

A model with IPX4 or IPX5 is not automatically suitable for swimming. Always follow the safety information and keep charging ports dry.

Frequently asked questions about wireless Bluetooth headphones

How do I connect Bluetooth headphones to my smartphone?

First, charge the headphones and activate Bluetooth on your smartphone. Put the headphones into pairing mode and select the product name from the list of available devices. The next time you connect, this will often happen automatically. If it does not work, remove the old pairing and restart both devices.

How long does the battery of wireless headphones last?

That depends on the model, volume, phone calls and features such as active noise cancelling. Therefore, check both the stated playback time and any separate figure with noise cancelling switched on. A charging case for wireless earbuds extends the total usage time, but the earbuds themselves still need to be recharged periodically.

Is a Bluetooth headset suitable for calls and meetings?

Yes, provided the model has a built-in microphone. Also check whether the manufacturer provides information about microphone noise reduction, multipoint and compatibility with your laptop or smartphone. Headphones with a microphone are practical for conversations, but clarity can vary depending on the room and background noise. Keep the volume moderate and take regular breaks when listening for long periods.
