Choosing wireless headphones: how to avoid a disappointing purchase

A pair of wireless headphones may seem simple to choose at first glance. You compare Bluetooth, battery life and price, then pick a model that looks appealing. However, the most important differences often lie in the details. For example, headphones may offer long battery life but feel heavy to wear. Or a model may be described as water-resistant when it is only protected against splashes.

For music, calls, travel, working from home and sport, three questions are particularly important: which wearing style suits your needs, how much surrounding noise do you want to hear and which specifications can be verified?

Common pitfalls when choosing wireless headphones

1. Battery life without the right context

Brands and retailers often state the maximum playback time. This figure can vary depending on volume, codec, active noise cancellation and phone calls. For example, an over-ear model may last up to 50 or 60 hours without noise cancellation, but less when this feature is active continuously.

So pay attention to battery life with noise cancellation switched on if you often travel or work in a busy office. Also check the charging port. USB-C headphones are practical if you already use a USB-C cable for your smartphone or laptop.

2. Noise cancellation is not always properly understood

Noise-cancelling headphones use active electronics to reduce certain surrounding sounds. Low, constant sounds such as train engines or air conditioning are generally the kind of noise this feature is designed for. Voices and sudden sounds may still be audible.

A transparency mode works in the opposite way: it lets surrounding sound through via the microphones. With open-ear headphones, awareness of your surroundings is an important part of the design, but music may therefore sound less isolated.

3. Water resistance is not waterproofing

An IP code consists of numbers and letters that indicate what a product is protected against. IPX4, for example, indicates protection against splashing water; IPX5 offers greater protection against water jets under certain conditions. Neither rating automatically means that you can submerge the product.

According to the product details, the Soundcore C40i and AeroFit 2 have IPX4 and IP55 ratings respectively. This makes them more suitable for sweating or light rain than models for which no water resistance is stated. Always check the manual and usage restrictions.

Key specifications explained

In-ear, over-ear or open-ear?

• In-ear earbuds sit in the ear canal and are compact. A good fit is important for comfort and sound isolation. Models supplied with multiple ear tip sizes give you more options for adjusting the fit.
• Wireless earbuds usually come with a charging case. Check the playback time of the earbuds themselves as well as the case’s total capacity.
• Over-ear headphones surround the ear. This can be comfortable during long train journeys or working hours, but pay attention to weight, clamping pressure and ventilation around the ear cups.
• Open-ear headphones rest beside or near the ear and leave the ear canal clear. This suits walking, cycling in quiet areas and sports where you want to remain aware of your surroundings. Sound isolation is limited as a result.
• Sports headphones need to stay securely in place. An ear hook, lightweight construction and a suitable IP rating are more practical than an impressive audio codec alone.

Bluetooth and connections

Bluetooth 5.2, 5.3 and 5.4 are current versions found in the models on offer. However, the Bluetooth version alone does not tell you everything about sound quality or range. Also look for support for multipoint, codecs such as AAC, SBC or LDAC, and a possible wired connection.

Headphones used for calls benefit from multiple microphones and well-positioned microphone placement. The product details for some Soundcore models list two, four or six microphones. This is a verifiable product specification, but how clearly you are heard ultimately also depends on wind, your surroundings and the phone connection.

Comfort and weight

Weight is particularly relevant during extended use. According to the product specifications, the Sony WH-CH720N weighs 192 grams, while the Sony ULT WEAR weighs 255 grams. A heavier model may offer extra features or larger ear cups, but it will not feel comfortable to every user.

With in-ear models, the shape and the supplied ear tip sizes are at least as important as the weight. With an over-ear model, also check whether the headband is adjustable and whether the ear cups fold for transport.

Frequently asked questions about wireless headphones

How do I connect Bluetooth headphones to my phone?

Switch on Bluetooth on your phone, turn on the headphones and activate pairing mode according to the manual. Then select the product name from the Bluetooth list. With some Apple models, a set-up window appears when you open the case near a compatible device.

How long do wireless headphones last?

Battery life depends on battery capacity, charging habits, volume and features such as noise cancellation. According to their product details, the models in this overview range from around 10 hours per charge for certain earbuds to up to 60 hours for an over-ear model. The battery itself deteriorates over time, so do not store the product completely flat for extended periods and use a suitable USB-C charger.

Are wireless headphones suitable for calls and work?

Yes, provided the model has a microphone and the fit suits your working environment. Headphones for calls with multiple microphones can be practical in a noisy environment, but also check for multipoint support if you want to use a laptop and smartphone at the same time. For a quiet home office, a simpler model without active noise cancellation may be sufficient.
