Christoph De Leeuw of the German magazine “Computer Bild” says that wireless headphones are very popular today, and explains: “These are completely wireless headphones, and they come in the form of” In-Ear “models, which fit easily in the pocket the if not used. ”

Most models have built-in microphones and allow hands-free phone calls on a smartphone.

These types of wireless headphones can be used during exercise, but with certain limitations.

Herbert Bisges, of the German “Hi-Fi” electronic portal, said: “Wireless headphones are mainly suitable for exercise, but small models quickly fall out of the ear during sports because they are loosely attached to the ear, in addition to the fact that the Wireless headset must be waterproof if a person sweats a lot. “

Sport models with additional earmuffs are a good choice when exercising, but many runners prefer to use lighter bow headphones.

sound quality

For hook-up headphones, the headphone pad rests on the outer flap, and these types of headphones are available in either wireless or wired models, and music lovers usually rely on traditional cable headphones.

“In terms of sound quality, there is no alternative to traditional headphones with a cable, because Bluetooth connection with current codex always involves a loss in quality compared to the accuracy of traditional discs,” said Jörg Dames of the German magazine ” Fire AudioD said. “.

In-air headphones are also considered a luxury class, delivering crystal clear sound when not wireless.

Damis added that the luxury In Air models are definitely popular today, and even the luxury headphones can be customized for individual requirements.

There are several international companies that manufacture models according to the customer’s requests, and Damis pointed out that “these models are characterized by portability, high quality sound reproduction and a lower degree of external noise, according to the accepted concept.”

However, these models offer a less surround sound experience than on-ear or “Over-Ear”, which is generally one of the disadvantages of headphones compared to regular headphones.

Cable earphones are still popular in the market even though there are no high sound quality requirements.

Damis added that the headphones are always powered by a cable, and the normal socket fits different models, and in the worst case, the user may need an adapter cable from the USB-C port to the regular socket if the smartphone does not does not support the sock.common.

Almost all wireless headphones rely on the Bluetooth standard, and Christophe de Leeuw says, “There are some headphones designed specifically for TVs that work with a special wireless standard, and in these cases a transmitter is required. unit within the device’s supply range. “

While headphones with Bluetooth technology are limited to pairing with only one device, the electronic market is seeing the rise of many models with the multi-pairing feature.

Jörg Pesges explained this feature by saying: “This type of headphone can store several devices such as a smartphone, a device, a laptop and a TV, which saves the user the hassle of reconnecting the headphones to each device separately. connect when there is between them. “

Noise canceling function

A practical and useful feature in the new headphones is the noise cancellation function, and “usually this function works through the reverse sound, which is generated,” says Besges.

This feature can be turned on and off by the user at will, also known as Active Noise Cancellation (ANC) feature.

There is a huge difference in the prices of the headphones available in the market today, and the choice of the type of headphones is often due to personal preferences.

Christophe de Leeuw, for his part, says: “There is a very good headset in all respects thanks to the splash protection function, compact dimensions, long battery life and sound quality, but it is also handy to use a wireless headset on the go and another large speaker. to enjoy music at home. “
