Headphones

There are basically different types of headphones, such as over-ear or in-ear, wired and wireless. A suitable pair can be found for everyone, adapting to individual needs and comfort. We reveal what types of headphones exist and what to consider when buying in our consumer tips.

How does a headphone work?

A headphone is a compact form of speakers that reproduce music from a stereo system, an MP3 player, smartphone, or other music players. They consist of two transducers, which are usually located directly on or in the ears. The transducers consist of a magnetic driver made up of a coil and a permanent magnet. When the electrical signal flows through the coil, the magnetic field changes, causing the driver to move and generate sound waves. The connecting cable between the transducers and the connector plug is often made of flexible material to increase freedom of movement. The connector plug typically has a diameter of 3.5 mm but can also have a diameter of 6.3 or 2.5 mm. The 3.5-millimetre jack is a standard connector used in most music playback devices. Some headphones also feature additional functions such as volume control, microphones, and remote controls, allowing calls to be answered or audio content to be controlled without having to pick up a device. Overall, headphones provide a simple and convenient way to enjoy music and other audio content in high quality.

What should be considered when buying headphones?

Sound quality is an important factor when choosing headphones. Headphones with clear, balanced sound and minimal distortion are recommended. Personal music and audio preferences should also be taken into account when making a decision. For bass lovers, headphones with good bass reproduction are suitable. Another important factor when buying headphones is comfort. It makes sense to find a comfortable pair if the headphones are to be worn for extended periods. Over-ear and on-ear headphones are generally the most comfortable. In-ear headphones should also fit comfortably. For noisy environments, good noise isolation is an important factor to consider. Headphones with good noise isolation are recommended to block out external sounds. Over-ear and on-ear headphones usually provide the best noise isolation, while in-ear headphones often isolate less.

What types of headphones are there?

• Over-ear headphones: Are a popular choice for audiophiles seeking an excellent listening experience. These headphones completely enclose the ear and provide optimal sound isolation, meaning that sound does not escape and ambient noise is blocked out. This allows for enjoying music at higher volumes without disturbing others nearby. However, they are often somewhat heavier and bulkier than other types of headphones, making them less portable. When buying over-ear headphones, it is important to pay attention to size, weight, and materials to ensure they are comfortable to wear.
• On-ear headphones: Offer a good balance between sound quality and wearing comfort. They sit on the ears and are generally smaller and lighter than over-ear headphones. This makes them easier to transport and provides a more comfortable fit for longer listening sessions. However, they may not offer the same sound isolation as over-ear headphones.
• In-ear headphones: Are very small and lightweight, offering excellent portability. They are inserted directly into the ear canal and provide good sound isolation to minimise external noise. They are a popular choice for use on the go, during sports, or for everyday use. However, they may not achieve the sound quality of larger headphones.
• True wireless headphones: A relatively new type of headphones that have no cable connection between the earbuds. They offer portability and freedom of movement, as there are no annoying cables. However, they may have poorer battery life and sound quality compared to other types of headphones.
• Noise-cancelling headphones: Are a popular choice for travellers and people working in noisy environments. They have special technology that blocks out background noise and provides brilliant sound quality. However, they are often more expensive than other types of headphones.
• Sport headphones: These headphones are specifically designed for use during sports or physical activities. They are usually sweat and water-resistant and provide a secure and comfortable fit during movement.

Which headphone design offers the best sound?

Over-ear headphones generally offer better sound quality and noise isolation, as they completely enclose the ears. In-ear headphones, on the other hand, provide better mobility and are often lighter and more compact, but may not always have the best sound and wearing them can be uncomfortable. On-ear headphones are a kind of compromise between over-ear and in-ear headphones, offering a good balance between sound quality and mobility. However, the transmission of audio data is also important, and one should inform themselves beforehand about which Bluetooth codecs the headphones support. The aptX codec and its improved version, aptX HD, generally provide better sound quality than the standard Bluetooth codec SBC, especially when transmitting higher resolution audio files. Sony's LDAC codec also offers a higher transmission rate and thus better sound quality than SBC.

What is the difference between open and closed headphones?

Open headphones have perforated ear cups that allow sound to escape and enable the perception of ambient noise. Open headphones are often lighter and airier than closed headphones and generally offer a wider and more natural soundstage. They are particularly well-suited for audiophiles who prefer a clear and precise sound.

Closed headphones, on the other hand, have closed ear cups that prevent sound from escaping and reduce ambient noise. This provides better isolation and can produce a more intense sound with strong bass. They are therefore ideal for situations where high volume is required or when working in a noisy environment.

Tips for buying headphones

• If you want to wear headphones for an extended period, it is important that they fit comfortably. Generally, over-ear and on-ear headphones are the most comfortable, but in-ear headphones should also fit comfortably.
• For noisy environments, good noise isolation is important to block out external sounds. One should opt for headphones with good noise-cancelling features.
• More expensive headphones often offer better sound quality, but there are also many affordable options with good sound and comfort.
• Athletes should pay attention to a secure fit.
