How to choose a good cost-effective earphone?
Headphones and headphones have become an important part of computer peripherals because of their portability. Especially for FPS gamers and HIFI enthusiasts, a good headset is the basic equipment for them to enjoy life. College Entrance Examination is over. Students will have their holidays one after another. It is believed that many people will buy a favorite headset to play games or listen to music during the summer vacation. Faced with the dazzling headphones in the market, how should we choose them? You may as well listen to me.
Recently, a famous headset forum has become a hot topic for netizens. The post reveals that HIFI headphones made by a famous brand of hearing aids rely on stimulating the auditory bones to achieve sound effect, but because of the unscientific design, wearing the headphones for a long time or exercising under the condition of wearing the headphones may lead to bleeding in the inner wall of the ear canal.
Let's start with the headphone box. There are usually the following parameters on the package: earphone structure, sensitivity, frequency response range, impedance, harmonic distortion and so on. What do they all represent?
Headphone structure - headphones are divided into headset type, earplug type and hanging ear type. Headphones have excellent performance and strong anti-falling ability, but they are large in size and inconvenient to carry, and are suitable for use in fixed places such as home or office. Earplug headphones are small, portable, sound quality is good, sound interaction is strong, but low frequency loss. The earphone combines the advantages of head-mounted and earplug-mounted headphones, which are fashionable in appearance and popular with young people.
Sensitivity - refers to the amount of input power required for a sound source at the same loudness. For portable devices such as Walkman, the higher the sensitivity, the easier the headphones to drive.
Impedance - Headphones with different impedance are used in different situations. High impedance headphones are usually used on desktop or power amplifier, VCD, DVD, TV and other machines. Low impedance headphones are generally used for various portable Walkman, such as CD, MD and MP3.
Harmonic distortion - The smaller the distortion, the better the sound quality.
Frequency response range - refers to the width of the frequency band that headphones can emit. The frequency response range of high fidelity headphones in IEC 581-10 standard is 50 Hz-12 500 Hz.
In addition, we should pay attention to product details when looking at genuine products. Wire, workmanship and handicraft are often the most powerful evidence to judge genuine products and aquatic products, brand names and miscellaneous brands. The last thing we have to do is to listen. Don't think your ears don't make any difference. Take your familiar source of programs and compare it over and over again to find your favorite headphones.
We need to remind you that the technical parameters are only one aspect when choosing and purchasing. When purchasing, we should treat the technical parameters more rationally. We don't need to spend more money to buy the functions we don't need for a little change in the parameters. We should not be confused by the slogans on the packaging of some miscellaneous headphones. The best one is the one that suits us. .
