What headphones are good Headphones are classified Different types of headphones compare choices

First, headphone classification:

1, the simplest method can be divided into head and ear style:

The head-mounted type is generally relatively large and has a certain weight, so it is not very convenient to carry, but its expressive ability is very strong, and it can make the music enjoyable in isolation.

The earbud type is mainly easy to travel and listen to music because of its small size. This headset is mainly used for CD Walkman, MP3 player, MD.

2. According to Transducer

It is mainly composed of dynamic and electrostatic headphones. Although there are several kinds of magnetic and electret type besides these two types, they have either been eliminated or used in professional markets. The amount of possession is very small and we will not discuss it here.

Dynamic earphones (also called electrodynamic): The vast majority (above 99%) of earphone earphones are of this type. The principle is similar to ordinary speakers. The coil in the permanent magnetic field is connected to the diaphragm and the coil is at the signal current. Drive the diaphragm to drive sound. Dynamic headsets are relatively efficient and can mostly be driven by stereo headphone outputs.

Electrostatic headphones (also called capacitive): The diaphragm is in a changing electric field, the diaphragm is extremely thin, accurate to a few microns (STAX's new-generation electrostatic headphone diaphragm has been accurate to 1.35 microns), coils in the electric field force Drive the diaphragm to drive sound. The level of sound pressure that an electrostatic headset can reach is not as large as a moving-type headset, but it has a fast response and can reproduce a variety of subtle details with minimal distortion. Due to its precise structure, high material requirements, and many manual assembly and commissioning, it is expensive.

There is also a dual-divide type earphone: A dual-range earphone is a dual-band crossover earphone that combines the advantages of both electric and capacitive based on a semi-open earphone. It combines the advantages of electro-, capacitive, closed, and open-type headphones (this is a real hybri). This kind of headphones, regardless of dynamic range, transient response, playback quality, Beats By Dre Sale The tone thickness and so on are all very outstanding, and its accurate voice resolution is the best choice for music enthusiasts.

From the use of the point of view, generally speaking, the electric headset has a simple structure, stable sound quality, low price and other characteristics, suitable for general use, it can meet the general needs; capacitive headphones, good sound quality and frequency bandwidth, but Due to the complexity of the process, the price is relatively high and it is suitable for enthusiasts to choose. Its listening quality is quite good.

3, divided by openness

Mainly open, semi-open, closed (closed)

The closed earphones wrap your ears with their own soft pads to completely cover them. These headsets have a large sound pad and are therefore quite large, but with a sound pad, they can be used in a noisy environment without being affected. The earmuffs have large oppression on the ears to prevent sounds from coming in and out, and the correct positioning of the sound is clear. This type of earphone has a disadvantage in that the bass sound is severely stained, and the W100 is an obvious example.

Open headphones are a popular style of headphones. The feature of this type of machine is that the sound-absorbing ear pad is made by using a sponge-like microcellular foam plastic. It is compact and comfortable to wear. It no longer uses heavy sound pads, so there is no sense of isolation from the outside world. The sound can be leaked, and vice versa. If the headset is open to a high degree, you can hear the sound from the other side of the unit, forming a certain amount of mutual feedback, making the sense of hearing natural. But its low-frequency losses are large, and some people say that its Cheap Beats By Dr Dre" href="/">Cheap Beats By Dr Dre low-frequency accuracy. Open headphones generally sound natural, comfortable to wear, and are commonly seen in home-appreciated HIFI headphones.

The semi-open earphone is a new type of earphone that combines the advantages of both closed and open type earphones (it is a hybrid, combining the advantages of the first two types of earphones, improving the inadequacies). Such headphones use 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 low frequency description, high-frequency description of bright and natural, clear layers and so on. Nowadays, it is the earphone that is widely used in many high-grade earphones.

Mainly Home, Portable, Monitor, Mix, Binaural Recording.

Second, different wired headphones have their own advantages

The traditional wired headphones can generally be divided into three types: in-ear style, in-ear style and head wear style. The three have their own advantages and disadvantages.

1. Earbuds

Small earphones placed in the ears, may use sponges to increase the adhesion.

Advantages: small size, light weight, easy to carry and collect.

Disadvantages: Whether you can wear it properly depends on the headphone design. Sometimes the headphone is too small and it will affect the degree of closeness.

2. In-ear (In-ear)

The earphones are shaped like earphones, and cushions are attached to the earpieces to press the earholes. Some in-ear earphones are claimed to have a soundproof design and can isolate part of the noise from low to high frequencies to achieve noise reduction.

Advantages: Lightweight and small, soundproofing effect is remarkable, in the noisy environment or can improve the sound quality.

Disadvantages: The size of the cushion may not be suitable for all users, and some brands/models come with multiple cushions. Although cushions may reduce noise, users may be uncomfortable with soundproof cushions that press against the ears.

3. Headphones

The left and right earphones are Beats By Dre On Sale supported by a headband, and the earphones are wrapped by a sponge or leather. When worn, the earphones or earphones are used.

Advantages: The ear-pressure design is generally lighter, but the sound insulation of the ears is better.

Disadvantages: Larger size, inconvenient to carry, if the pressure is too high or poor gas design is not good, will reduce comfort.

Third, the wireless headset features and limitations

In addition to traditional wired headsets, wireless headsets have become increasingly popular. Wireless headsets generally use infrared, radio frequency, or Bluetooth to send messages.

Infrared earphone

Features: Must be transmitted within the line of sight, the application of the location is limited, but less interference.

Restrictions: In the event of strong sunlight, signal transmission may be affected.

2. RF wireless headphones

Features: High penetrating power. Users can listen to music in indoor or outdoor environments within about 100 meters. However, the farther the distance is, the more affected the sound.

Limitations: RF headphones are vulnerable to other signals due to their long range, and may misunderstand the music emitted by another transmitter. Therefore, RF headphones usually have two or three band options, such as using multiple infrared or radio frequency in the same place. Headphones, as long as you tune to the same band can receive signals at the same time, all users can listen at the same time.

3. Bluetooth headset

Features: Bluetooth headsets that use digital RF transmission can avoid signal interference or erroneous message reception.

Restrictions: Some models can be connected to regular players using regular 3.5mm connections, and some models can only be paired with individual Bluetooth-designed players or mobile phones. In addition, because of the limited design and transmission power of Bluetooth, the transmission distance is short and it is generally suitable for portable players.

Fourth, closed and open

The space inside the closed earphone is separated from the outside, and the cushion or sponge covers the ears to achieve a high degree of shielding effect and less leakage of sound.

The open earphone shell usually has a lot of small holes, which makes the sound more balanced and natural. Because of better design ventilation, it may be more suitable for hot and humid climate or long-term use.

Fifth, noise reduction and noise are different

Some headphones have a noise cancelling (abbreviation) design, claiming that electronic noise reduction can be used, especially for continuous low-frequency noise. However, these types of noise reduction circuits require power. Some models will not only lose their noise reduction function without a battery, but they will not be able to continue listening to music. Users need to pay attention.

Some in-ear models claim to be isolating or isolator design. The cushions on the headphones press firmly against the ear canal to isolate many low-to-high-frequency noises, so it can also reduce external noise. The user must understand the difference between noise reduction and noise reduction methods. The former is active, requires power supply and circuitry, and the latter relies only on earplug sponges or cushions and does not require batteries or charging.

Six, headphone accessories

Many larger earphone models come with large or small earphone (6.35mm or 3.5mm) conversion plugs to match the headphone jacks of home audio sets, miniaturized or portable audio devices, and compact headphone models for walkmans, etc. Portable devices are only equipped with small plugs.

In-ear headphones are generally supplied with different sizes of soft rubber sleeves to match the size of the ear holes of different users. Some models also have an organic cabin seat plug for listening to music while flying.

Try to use carefully selected headphones

If you can try it before you buy it, you should try it on. After you try it on, you can turn your body or move your head and neck. Test whether the headset will easily shift or fall. If the headphones are not designed or match the ear holes, it will affect the wear. Comfort. Headphones usually have a headband close to the ear, not easy to walk, usually covered with soft skin or thick sponge, wear more comfortable, but users should also pay attention to when the weather is hot and hot, soft skin and sponge may bring sultry The feeling is that the material is more susceptible to dampness, so it should be properly stored after use.
