Choose The Perfect FreelaceHuawei Usages: What You Need

Headphones for smartphones – accessories are so popular that their range is growing every year. How to figure it out and buy the ones that suit you perfectly? Try to follow our guide.

Wired or Wireless?

  • The first fundamental question that you have to solve. It is difficult to say which type is preferable.
  • Wired headphones do not require a power source. They will never be discharged and will not shut up, and this is what many users like. But there are also disadvantages: the wires are always tangled, and besides, not every gadget has a connector for connecting such accessories.
  • Wireless headphones give you complete freedom of action. No wires, no need to untangle anything. But they run on a battery, and it tends to discharge at the most inopportune moment.

Wireless headphones can also be divided into two classes. The most popular for today is TWS (True Wireless Stereo). These are two miniature devices that connect via Bluetooth. Another option is almost wireless. This is the same miniature device, but connected to each other by a wire and a neckband.

Everyone has advantages. For Huaweii, this is, of course, compactness and ease of wearing. On the other hand, neckband headphones are always ready to use, no need to look for them in your pocket or bag. They are ideal as a headset – for example, to answer a call, simply insert one of the earbuds into your ear.

One of the latest models with a bezel is the freelace huawei Pro with Active Noise Cancellation (more on that later). A 5-minute USB-C charge gives you 5 hours of use. A full charge of the battery provides up to 24 hours of continuous sound (with the muffler turned off).

Headphone types

When you have already decided on the presence of wires (or lack of them), you should think about the type of headphones. There are not many of them.

Vacuum

They are inserted directly into the ear canal and held there by a silicone seal. There is excellent isolation from external noise. But not everyone is suitable; someone with such “gags” is simply uncomfortable.

Earbuds

They are also inserted into the ear, but not into the canal, but into the auricle. With this placement, there is practically no discomfort. But there is no noise isolation, besides, this type does not always hold securely in the ear.

Overhead

As the name implies, they are worn on the ears – the speakers are installed in cups that have a headband. This type can be divided into two: some (open type) only cover the auricle, that is, put on it. Others (closed) completely cover the ear, leaving the concha inside. In the latter case, noise isolation is better, but the headphones are also more massive.

Noise reduction: passive and active

The desire to listen to music, rather than its mixture with city noise, is quite understandable. Two technologies can be used to get rid of extraneous sounds.

Passive noise isolation

These are various options for physically blocking the auditory canal. For example, in vacuum headphones, isolation is achieved through the use of a silicone seal: it is this seal that protects the channel from noise. It is more difficult with overhead models, but if the cups cover the auricle and fit snugly to the face, the noise isolation will also be at a good level.

Active noise cancellation: Much more complex technology

Special headphone microphones pick up noise, and then the devices generate the same sound wave in antiphase. As a result, much fewer extraneous sounds enter the ear canal. This technology is used in headphones not lower than the average price range. Active noise canceling is already available not only in full-size on-ear headphones, but also in compact models, for example, HuaweiFreeBuds.
