What headset good headset classification different types of headset contrast selection

First, headset classification:

1, the most simple sub-law, can be divided into headset and ear plug type:

Headset is generally larger, have a certain weight, so easy to carry, but its expressive force is very strong, can make the world to enjoy the wonderful music.

Earbuds are mainly easy to travel out to listen to music because it's small in size. This type of headset is mainly used for CD audio, MP3 player, MD.

2, according to the principle of conversion (Transducer) points

Mainly dynamic (static) and electrostatic (Electrostatic) headphones two categories, although in addition to these two categories are equal to magnetic, electret and other species, but has been eliminated or for professional use market Possession of very little, do not discuss here.

Moving headphones (also known as electric): the vast majority (about 99%) of the headset earplugs are such, the principle is similar to ordinary speakers, in the permanent magnetic field coil connected with the diaphragm, the coil in the signal current Driven under the vibration diaphragm. Moving coil headset efficiency is relatively high, mostly for the audio on the headphone output driver.

Electrostatic headphones (also known as capacitive): The diaphragm is in a changing electric field, the diaphragm is extremely thin, accurate to a few microns (currently STAX new generation of static earphone diaphragm has been accurate to 1.35 microns), the coil in the electric field force Driven under the vibration diaphragm. Static headphones can reach the sound pressure level without moving coil headphones, but it's fast response, can reproduce a variety of small details, very low distortion. Because of its sophisticated structure, the material requirements are high, and more for manual assembly debugging, so expensive.

There is also a dual-split headphones: dual-split headphones in the semi-open headphones based on the integration of both electric and capacitive advantages of their own dual-band headphones. It combines the advantages of electric, capacitive, closed, open four headphones in one, (this is a real "hybrid") such headphones in terms of dynamic range, transient response, playback quality, Sound thickness and so on are very outstanding, and its voice resolution is the best choice for music enthusiasts.

By the use of the situation, in general, the electric headset has a simple structure, stable sound quality, cheap and so on, suitable for the general selection, it can meet the general needs; capacitive headphones, good sound quality and bandwidth, but As the complexity of the process, the price is relatively high, suitable for enthusiasts use, its listening quality is quite good.

3, according to open degree points

Mainly open, semi-open, closed (closed)

A closed headset wraps your ear through its own soft pad to cover it completely. Such headphones because of a large sound pad, so the head is also larger, but with the sound pad can be used in a noisy environment without being affected. Earmuffs are more oppressive to the ears to prevent sound from entering and leaving, the sound is clearly positioned, and the professional surveillance field is more common in this field. However, there is a drawback that the headphones have a drawback that the bass is serious and the W100 is an obvious example.

Open headphones are more popular headset styles. This type of machine is characterized by the use of sponge-like microporous foam plastic production sound ear pads. It is small, wearing a very comfortable, no longer use heavy dye pad, so there is no isolation with the outside world, the sound can be leaked, and vice versa can also hear the voice of the outside world. If the headset is open to a high degree, you can hear the other side of the unit issued a sound, the formation of a certain feedback, making a sense of natural. But its low frequency loss is large, some people say it's low frequency accurate. Open headphones generally feel natural, comfortable to wear, common in the home to enjoy the HIFI headphones.

Semi-open headphones are a combination of closed and open two headphones advantages of the new headphones (it is a half-breed, the integration of the advantages of the first two headphones to improve the shortcomings), such headphones using a multi-diaphragm structure , In addition to an active active diaphragm, there are a number of passive driven diaphragm. It has a low frequency to describe the fullness of the rich, high-frequency description of bright and natural, clear levels and many other features, and now many of the higher grades of headphones is widely used in this headset.

4, according to the use of points

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

Second, different connection headset have their own advantages

Traditional connection headphones can generally be divided into ear type, ear type and head type three, the three have their own advantages and disadvantages.

Earluds

Placed in the ear of the small headphones, the use may be put on the sponge to increase the degree of tightness.

Advantages: small size, lightweight design, easy to collect to carry.

Disadvantages: whether to wear properly depends on the headset design, sometimes too small headphones will affect the close.

2. In-ear (In-ear)

Headphones like earplugs, headphones attached to the pad for the pressure ear, part of the ear headphones claim to have sound insulation design, isolated from low to high frequency noise, to reduce the noise effect.

Advantages: light and small, sound effects are more significant, in noisy environment or can improve the sound quality.

Disadvantages: pad size may not be suitable for all users, some brands / models with multiple cushions. Although the cushion may reduce the noise, but the user may not accustomed to sound insulation pad pressure ear.

3. Headphones

Left and right headphones to headband support, headphones wrapped by sponge or leather, wearing a pressure ear or ear when the ear type.

Advantages: pressure ear design is generally more lightweight, but the ear of the sound insulation is better.

Disadvantages: larger, more inconvenient to carry, if the pressure is too large or poor design, will reduce the comfort.

Third, the characteristics of wireless headset and restrictions

In addition to the traditional connection headset, wireless headset is also becoming popular, wireless headset generally use infrared, radio or Bluetooth to send messages.

1. Infrared headphones

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

Restrictions: Signal transmission may be affected under violent sunlight.

2. RF wireless headset

Features: high penetration ability, the user within about 100 meters of the environment, whether indoor or outdoor, still can hear the music, but the more distant sound more affected.

Restrictions: RF headphones are far from the "range" and are susceptible to interference from other signals, and may miss out on the music emitted by another launch point, so the RF headset usually has two or three bands, such as using multiple infrared or radio frequencies in the same place Headphones, as long as the tuning to the same band can receive signals at the same time, the user can listen at the same time.

3. Bluetooth headset

Features: The use of digital radio transmission of Bluetooth headset, to avoid the signal interference or the wrong message to receive the situation.

Restrictions: Some models can be connected to a normal 3.5 mm wired connector, and some models can only be paired with individual Bluetooth-designed players or mobile phones. In addition, because the Bluetooth design and transmission power is limited, the transmission distance is short, generally suitable for portable player use.

Four, closed and open

Closed headset space and separated from the outside, coupled with the pad or sponge cover the ear, can achieve a high degree of shielding effect, leakage is also less.

Open headphones shells usually have a lot of holes, forming a more balanced natural sound. Because the design ventilation is better, perhaps more suitable for hot and humid climate or long-term use.

Fifth, noise and noise are different

Some headphones are designed to reduce noise (noise cancellation), claiming that electronic noise can be used, especially for continuous low-frequency noise. However, these models of noise reduction circuit requires power, some models in the absence of battery when not only lose noise reduction function, but can not continue to listen to music, users need to pay attention.

Part of the ear type claims to have sound insulation (isolating or isolator) design, relying on the headset of the pad pressure on the ear hole, can be isolated from many low to high frequency noise, it can also reduce the external noise. Users need to understand the noise reduction and noise reduction methods of noise, the former is active, the need for power and circuit, the latter only rely on earplugs sponge or pad, do not have to enter the battery or charge.

Six headset accessories

Many of the larger headset models are equipped with large or small headphones (6.35 mm or 3.5 mm) conversion plugs to match the headset jacks for home audio combinations, miniature or portable audio equipment; compact headset models for Walkman, etc. Portable equipment, only with a small plug.

In-ear style earphones are generally attached to different sizes of soft sets, with different user ear size. Some models also have a cabin seat plug, easy to take the plane to listen to music.

Try to use a comfortable and comfortable headset

If you can try before you buy, you should try to wear, try to turn the body or move the head and neck, test headphones will easily shift or fall, if the headset is not designed or does not match with the ear, will affect the wear Of comfort. The headset is usually equipped with a headband close to the ear, easy to walk, generally wrapped in soft leather or thick sponge, wearing more comfortable, but the user should also pay attention to the weather is hot and hot, soft leather and sponge may bring hot Of the feeling, and the material is more susceptible to mold moisture, so after use should be properly collected.
