Wireless Bluetooth headphones are part of everyday life for many people: on the train, working from home, exercising, gaming or making phone calls. The choice ranges from compact true wireless earbuds to comfortable over-ear models. However, the technical terms used on packaging and product pages are not always directly comparable.
Three common buying misconceptions particularly often lead to the wrong decision:
Over-ear headphones completely surround the ear. They usually offer larger ear cushions, passive noise isolation and room for high-capacity batteries. This makes them suitable for commuters, travellers and long listening sessions. According to the product specifications, models such as the Sony WH-CH720N weigh 192 g, while the JBL LIVE 770NC weighs 256 g. Weight and clamping force should be taken into account during extended use.
On-ear headphones rest on the ear and are often lighter and more compact. The Sony WH-CH520 weighs 147 g, making it an interesting option for users who prefer a lightweight design. However, the open space between the ear cushion and the ear can allow more surrounding noise through.
In-ear headphones and true wireless earbuds sit directly in or around the ear canal. They are suitable for use on the go, phone calls and exercise. Check whether different ear tips are included and whether the stated IP rating is genuinely suitable for your intended use. IPX5, for example, means protection against water jets, not prolonged submersion.
With Bluetooth headphones featuring ANC, microphones generate an opposing signal to counter certain types of surrounding noise. Low-frequency rumbling from trains, aircraft or buses can often be handled more effectively than changing voices. A transparency mode can be useful when you need to hear announcements or remain aware of your surroundings.
You should also pay attention to the microphone specifications. Headphones with a microphone may be suitable for music, but voice transmission can vary in clarity in windy conditions or with voices in the background. Beamforming microphones and multiple microphones are objectively describable features, but they do not guarantee a particular level of call quality.
Always compare these three figures:
The Sony WH-CH720N is specified to provide up to 35 hours with ANC activated and up to 50 hours without ANC. According to the product description, the JBL LIVE 770NC can deliver up to 50 hours with Bluetooth and ANC, and up to 65 hours in total. According to the manufacturer, the JBL Tune 720BT achieves up to 76 hours without ANC.
A fast-charging function is particularly convenient for professionals and travellers. The Sony WH-CH720N is designed to provide up to 60 minutes of playback from three minutes of charging. The JBL LIVE 770NC is specified to provide up to four additional hours after five minutes. Actual battery life depends, among other things, on volume, codec, ANC and operating temperature.
Bluetooth versions such as 5.3, 5.4 or 6.0 can support modern energy-saving and connectivity features. However, it is also important to check whether your smartphone, tablet, laptop or games console is compatible. Multipoint Bluetooth is useful for home workers who want to connect two devices at the same time.

We have put together a complete, regularly updated list of products that fully meet these strict selection criteria and the safety regulations applicable in the EU.
Put the headphones into pairing mode, open the Bluetooth settings on your smartphone and select the device name shown. With models featuring Google Fast Pair, Microsoft Swift Pair or a manufacturer’s app, setup may be quicker. If you experience connection problems, check whether the device is already connected to another smartphone or laptop.
Their service life depends on the battery, hinges, ear cushions and care. Built-in lithium-ion batteries are generally not designed to be replaced by the user. Store the headphones in a dry place, avoid excessive heat and only charge them with suitable cables or certified chargers. With sports models, pay attention to the stated protection rating.
Their power consumption is low compared with many larger electronic devices. Even so, earbuds and their charging case need to be charged regularly. A fast-charging function reduces waiting times, but it does not replace a realistic check of battery life with ANC. If you often use your headphones on the go, compare the actual playback time per charge with the total battery life including the charging case.
Note: Do not listen at high volume for extended periods. Do not use ANC or closed noise-cancelling headphones in situations where you need to hear traffic noise or warning signals clearly.
