Disadvantages: The wire is bound, too short is inconvenient, too long is easy to be hung and entangled. How to store the hook behind the door; fix it with clips; tie it with wire. Wired earphones or Bluetooth earphones is better In terms of sound quality stability, wired earphones are better than bluetooth earphones, and they are more cost-effective. But from the point of view of portability and function, bluetooth earphones are better, because bluetooth earphones are not bound by lines, they can do other things while listening to songs, and bluetooth earphones have practical functions such as redialing, call retention and rejection. Function. Headphones by use Definition: Refers to a kind of headphones that use a certain method to reduce noise, currently divided into active noise-cancelling headphones and passive noise-cancelling headphones. Do noise-cancelling headphones damage hearing? Noise-cancelling headphones avoid the impact of long-term high volume on the eardrum, thus effectively protecting hearing. Gaming headset Features: Pay more attention to the sound field and sense of positioning (for example, shooting and gunfighting games require positioning), and at the same time increase the amount and intensity of low frequencies, thereby satisfying the user’s experience of game sound effects. Buying skills: Generally speaking, the bigger the speaker unit, the better, so the head-mounted type is better than the in-ear type. The reason is that the in-ear type does not support large speaker units due to its size. hifi earphones Definition: I understand that hifi earphones are high-fidelity earphones that can reproduce sound that is highly similar to the original. Buying skills: For ordinary music lovers who don’t want to toss, a good closed-back Bluetooth headset can completely solve your needs in all aspects.

What earphones to wear for running: It is better to have as little body load as possible when running. Therefore, you need to pay attention to lightness and firmness, and you can choose in-ear or semi-in-ear earphones. For those who like to run at night, it is safer to choose a Bluetooth headset with reflective material. Bone conduction earphones Definition: It can convert sound into mechanical vibrations of different frequencies, and transmit sound waves through the human skull, bone labyrinth, inner ear lymph, auger, and auditory center. Advantages: Open both ears when wearing, do not block the ears, and solve the discomfort of wearing in-ear headphones. Disadvantages: At present, major manufacturers are trying to improve the sound leakage of bone conduction headphones, but the sound leakage phenomenon still exists. Subwoofer Headphones Definition: Subwoofer headphones sound heavy and thick, perfect for listening to DJ and DISCO music. Are subwoofer headphones good for your ears? Control the volume and wear it for no more than 2 hours a day. Generally speaking, it will not have a great impact on hearing. Stereo headphones Definition: It has a wide frequency response, low distortion, power saving, strong audio resolution, good surround sound resolution, and a strong sense of music rhythm. Stereo headphones or subwoofer headphones which is better? Subwoofer headphones have lower sound frequencies, more powerful and closer to the real. Stereo headphones have a higher sound frequency, and use the time difference between the two ears to form a more realistic sensory scene. Monitoring headphones Definition: refers to the headphones that can hear the sound quality that is closest to the real, without any modification, so it has less signal distortion and can clearly reflect the sound characteristics of the monitored object. Are monitor headphones good for listening to music? Monitor headphones are equivalent to full fidelity. Through monitoring headphones, you can hear the closest to real, untouched sound quality. FM earphones: The earphones are equipped with function buttons for radio frequency modulation. Such special FM earphones will have a receiving line, which is very convenient for those who often listen to FM radio broadcasts.

Card headset: similar to the extension of portable small speakers, built-in decoding chip, support TFSD card, independent playback from the front end; with multi-function buttons for easy operation. It looks like a “wireless” headset, but it can be connected to a computer, MP3, etc. through an audio cable. Waterproof headphones: There is a big difference between whether the headphones have waterproof performance and whether they can be waterproof. Different grades correspond to different waterproof performance. Low-grade waterproofing often limits the direction of incoming water, water flow speed, water pressure, etc. Water accident in a complex environment. Business Headphones Business Headphones are specially designed for business people to answer the phone in office. There are multi-connected Bluetooth headsets, single-ear Bluetooth headsets, etc., whether they are driving or busy at work, Can answer the phone in a timely manner.

For example, control the on/off function, play and stop function, and volume adjustment function of the remote MP3 device. Headphones are classified by wearing style In-ear headphones: Plug them directly into the ears in a comfortable way, just like the rubber-type wired headphones we usually use. The advantage of the plug-in type is that it is light, and the portability is the best among all types of headphones. In-ear headphones: On the basis of ordinary headphones, in-ear headphones are inserted into the ear canal with a rubber plug to obtain better airtightness. Greatly increases the performance of the headset. This headset reduces the interference of external noise on the music and reduces sound leakage. Ear-hook earphones: A pair of foldable hooks are attached to the earphones so that they can be hung on the inside of the auricle, and earphones using such a wearing system can be regarded as ear-hook earphones. However, since it is impossible to hang it close to the auricle, there will always be a problem of sound leakage. Headphones: The most common type of headphone, using an elastic headband to clamp the pinna from the top of the head. The earmuffs are generally designed to be relatively large due to the lack of consideration of lightness. This kind of earphones is very well developed, and generally the headband can be adapted, and the earmuffs can be rotated slightly. Back-hook headphones: Headphones that use an elastic headband to clip the headphones from the back of the head around the auricle so that the earcups fit snugly against the auricle.

Lavalier Headphones: Can be clipped on the collar, pull out the headphone head when in use, and retract the headphone head without pressing the cable retraction button, which is convenient and lightweight, leaving no burden on the ears. The earphones are divided according to the sounding principle Moving iron earphone: The moving iron is driven by a permanent magnet and a set of coils. The center point of the diaphragm, which produces vibration and sound. In contrast, moving iron headphones are widely used because of their high sound quality and small size. Moving coil headphones: Moving coil headphones are our common ordinary headphones, and their drive unit is a circle-shaped speaker, so they are called “moving coil headphones”. The vast majority of earphones and earplugs are dynamic earphones. The principle is similar to that of ordinary speakers. The dynamic coil mainly relies on the vibration of the diaphragm to produce sound. To put it bluntly, it is a reduced version of the small speaker. Electrostatic earphone: The electrostatic earphone is that the middle diaphragm is charged with static electricity, and the working bias is applied to the plates on both sides. When a signal comes in, according to the principle that the electrodes of the same sex repel and the opposite sex attracts, the diaphragm will vibrated. Because of the high content of electrostatic technology and high cost, most of the electrostatic earphones on the market cost more than 10,000 yuan. Headphones are classified according to the degree of opening Closed-back headphones: wrap your ears with their own soft sound pads, which can be used in noisy environments without being affected. The earmuffs put a lot of pressure on the ears to prevent the sound from entering and leaving, and the sound is positioned correctly and clearly. This type of earphone is often seen in the field of professional monitoring. Open earphones: Open earphones refer to the sound-transmitting earpads made of sponge-like microporous foamed plastics, which are small in size, comfortable to wear, natural and comfortable to wear, and are commonly used in home HIFI earphones. Semi-Open: This type of earphone adopts a multi-diaphragm structure, in addition to an active active diaphragm, there are multiple passive driven diaphragms. It has many characteristics such as rich and rich low-frequency description, bright and natural high-frequency description, and clear layers. Today, many higher-end headphones are widely used in this kind of headphones.
