Headphones to mobile phones are subject to subjects that a person most often carries with them along with the phone and clock. These devices made music available anywhere. Products supplied with phones, low quality, soon fail. When choosing a new headset, you should deal with the features of the designs and operational characteristics of the device.
1
Insert headphones are compact, easily transferred. Can be located inside the ear canal or fasten in the ear sink.
2
The first is often called vacuum, they are tightly placed in the ears, do not miss outsiders. Good headphones are supplied with replaceable tips of soft material to eliminate inconvenience when using.
3
Devices installed in the ears are fixed in various ways. If you have long hair, buy a device with fixation on your ear, so hairstyle does not deteriorate. In winter, when we carry a headdress, use the handles on the neck. Athletes recommended special devices with ergonomic fastening that does not fall during training.
4
Closed headphones cover their heads from above. They reproduce music better. Cups should be separated by soft materials, ears do not go beyond cups. The dimensions of the forehead must be adjusted.
5
Choose headphones with a special storage box headset. This will solve the problem with confusion of wires. Also not confused flat wire made in the form of a telephone wire.
6
Check the length of the wire, it should be enough from the place of the alleged location of the phone to the ears. For phones, headphones with no more than 1.5 m are usually supplied.
7
Wireless systems are convenient for use, but the quality of the sound is worse and they require special operating conditions. Bluetooth headsets are valid if there are no more than 10 m between the phone and headphones. Models with IR sensors must be within the visibility of the phone. Professional in-ear headphones are very expensive.
8
Headphones for phones should have a high sensitivity - 100-120 dB. Low values \u200b\u200bwill distort the sound, high give off, but will provide a greater volume.
9
Check the frequency range. The format of MRCs, in which most musical works are written, deprived of high frequencies. The optimal frequency range is 20-16000 Hz.
10
Learn the electrical resistance of headphones and compare with the output of the phone. The agreed resistance will ensure the maximum volume and high sound quality.
11
Learn the harmonic distortion coefficient. This value is on the packaging of the goods. Good quality in products with a coefficient of less than 0.5%. If it is impossible to find data, it means that the manufacturer has something to hide.
12
Ask the output power of product speakers. What it is higher, the brighter and more juicy. However, powerful devices (2000-3000 MW) quickly discharge phone batteries.
The price does not always determine the quality of the headphones. Sample the headset before buying. Take just the model that you liked, with such a purchase you will feel comfortable.
