Today, we only investigate the subjective listening evaluation of headphones, the necessary steps we choose headphones.
To properly evaluate the sound of the headphones we must first understand the characteristics of the sound of the headphones. Headphone speakers can not match advantage, phase distortion, wide frequency response, transient response, rich in detail, you can restore the delicate lifelike sound. But the headset has two drawbacks accurate to say that two features of the headphones, they are relative to the body's physical location decided by the headset.
The first feature is: Headphone "head effect.
Headphones create acoustic environment is nature, nature sound waves into the ear canal with the head and ears interaction, the sound from headphones directly into the ear canal; record most of the speakers weight put production, audio and video in two speakers connected online, for two reasons when we use headphones feel the sound image is formed in the head and in the sense of hearing is not natural, easy to cause fatigue. The headphones "head" effect can be improved through the use of special physical structure, sound field simulation software and hardware in the market, there are many.
The second characteristic is: low frequency headphones.
Low frequency under paragraph (40Hz-20Hz) and ultra-low frequency (20Hz) is perceived through the body, the human ear is sensitive to these bands. Perfect headset can replay this low frequency, but because the body does not feel that the low-frequency, will make people feel enough bass headphones.
Since the listening mode and speaker of the headset is different,[http://www.monsterbeats-bydre.de/beats-by-dr-dre-nhl-c-16.html Beats by Dr Dre NHL], the headset sound equalizer is a unique way. Headphone high frequency in general improved, so that gives the feeling to the detail-rich sound balance; a completely flat low frequency headphones often feel a lack of low-frequency sound slim, appropriate to enhance the low frequency is also headphones often used means this could make the sound of the headphones look plump, low dive deep. The most commonly used means of lightweight headphones and earplugs, their small diaphragm area can not reproduce the deep bass, you can get a satisfactory low-frequency effects enhance the low-frequency middle (80Hz-40Hz).
Real voice is not necessarily beautiful,[http://www.monsterbeatsby.de/ monster beats], these two methods are effective in headphone design,[http://www.monsterbeats-bydre.de/monster-beats-studio-c-1.html Monster Beats Studio], but going too far the excessive enhance high-frequency and low-frequency will destroy the balance of sound, sound stimulus can cause fatigue. IF headset is a sensitive area, where the music most abundant, but also the human ear is most sensitive. Headphones designed to treat IF cautious, low-grade headphones frequency response range is limited bright, sharp tone and muddy, but by mentioning enhance IF the upper section and the lower the intensity of the sound, resulting in the illusion of good high and low frequency, long listen to this headset will feel dull.
The headphones sound should have the following characteristics:
First, the end of pure sound, without any unpleasant "hiss", "Om", "coax" sound.
Balance good tone from but bright or too dark, high frequency energy distribution uniform fusion band naturally smooth, non-obtrusive and burr.
Third, the high-frequency extension is good, delicate and supple.
Low frequency dive deep, clean and full of elasticity and strength, no fat, slow feeling.
IF distortion is extremely small, transparent, warm, kind of natural human voice,[http://www.monsterbeats-bydre.de/monster-beats-studio-c-1.html monster beats studio kopfhörer], the thickness of the magnetic, no exaggeration tooth tone and twang.
, Resolution, rich in detail, the tiny clear signal reproduction.
VII, good sound field portrayed ability sound field, accurate and stable instrument, the sound field in a sufficient amount of information, there is no empty feeling.
Eight dynamic no obvious compression, has a good sense of speed, large volume without distortion or distortion is very small.
A headset perfect replay any type of music, good as the real and the music a sense of long-term use will not cause fatigue, enabling the listener immersed in music.

== coupled considered ergonomic design on the ear pad ==

Due to the original headphones has the appearance of serious wear and tear, really rather a chance to disgrace, so in October 29, 2007, Philips acquired 115 Ocean SHP2000.
Single appearance and workmanship, it is indeed a value stuff:
1, headphones large,[http://www.monsterbeats-bydre.de/monster-beats-lebron-james-c-10.html monster power lebron james beats], can be the entire ear inclusion into the ear pad is pressed directly in the skull, rather than the auricle, coupled considered ergonomic design on the ear pad, so long wear does not like most headphones , ear pressure, raw pain.
2 ear cushions fabric material, not man-made leather, does not produce large amounts of debris because of aging,[http://www.monsterbeats-bydre.de/monster-beats-solo-hd-c-3.html monster cable beats by dr. dre solo hd], permeability is good, no hot feeling,[http://www.monsterbeatsby.de/ dr dre monster beats], do not know that summer is what will happen, estimated should be pretty good.
Wire using two-rather than the most inexpensive headphones singlet, and relatively thick, high fracture resistance; volume adjuster These are reference to the design of high-end headphones; without a microphone (which is inevitable, or would not be called the headphones should change the name headset).
4, although the entire headset big, but because it is the shell of plastic material used, the whole is not very amount of feeling can also bring in the head.
Then said the most critical sound quality, we contact the headset is not much, dare not judge, but SHP2000's very obvious shortcomings, and has been hard to tolerate the degree ---- S sound very sharp soprano, has reached a strident extent by adjusting the sound card's equalizer, lowered its full response 7KHz ~ 9KHz band 7 dB improvement or he feels harsh. Do not know because there is no fort open headphones yet to achieve the best working condition. Alone this one,[http://www.monsterbeatsby.de/ beats kopfhörer], my heart suddenly stumbled. In addition there is a sort of a small drawback: the sound leakage, it seems that the headphones seal is not good, the evening may affect others rest.
As for SHP2000 good performance in other bands, low frequency can be excellent to represent good midrange. Playing games and watching movies completely be able to get a good treat.
But that serious drawback to its very disappointed, want to be able to later draw a write this review.

== so in general the higher the sensitivity ==
+

Impedance (Impedance): Note resistance meaning distinction in the world of direct current (DC), the objects on the current role in obstructing called resistance, but in the field of alternating current (AC), except that the resistance will hinder current, capacitance and inductancealso impede the flow of current,[http://www.monsterbeats-bydre.de/lady-gaga-heartbeats-c-20.html lady gaga heartbeats by monster cable], and this effect is called the reactance, and the impedance is a resistance and reactance in the vector and our daily said.
Sensitivity (Sensitivity): point the headphone input power of 1 mW headphone can be issued SPL (sound pressure decibels sound pressure the greater the volume the greater), so in general the higher the sensitivity, the smaller the impedance headphones the more likely it out loud, the more likely to drive.
Frequency response (Frequency Response): the frequency corresponding to the sensitivity of the value is the frequency response, plotted as the image is the frequency response curve, the range of human hearing can reach about 20Hz-20000Hz, mature headphone technology have reached this requirements.
Range: musical instruments or the human voice can reach the range between the highest sound and contrabass
Voices: also known as timbre, one of the basic properties of sound, such as the erhu,[http://www.monsterbeats-bydre.de/beats-by-dr-dre-nhl-c-16.html Beats by Dr Dre NHL], pipa is a different tone
The coloration: Music natural neutral antithesis, that sound contracting program itself does not have some of the features, such as facing a jar speech,[http://www.monsterbeatsby.de/ http://www.monsterbeatsby.de/], the kind of sound that is typical coloration. Coloration indicate that more (or less) certain components in the signal reproduced, which is obviously a distortion.
Sound field: speakers produce the sum of the spatial relationships in different voices and their status.
Positioning: audio playback space presented in the pronunciation device of the three-dimensional distribution of a fixed position.
Distortion: the output of the device is not completely reproduce its input,[http://www.monsterbeats-bydre.de/monster-beats-graffiti-c-4.html Monster Beats Graffiti], resulting in the increase or decrease in the waveform distortion or signal components.
Dynamic: Allows record the ratio of the maximum information with minimum information
Transient response: equipment the ability to follow the music burst signal. The transient response good equipment should be a signal to respond immediately signal a stop braked to a halt, by no means clear-cut. (Typical instruments: piano)

In 1924, German scientists in Berlin opened an electronics factory developed small speakers, and they fixed curved hoop rack, so the world's first headphones so was born! In 1945, after World War II Vienna Allied occupation, war almost destroyed Vienna. It is also in this year, Dr. of Rudolf Goerike and Ing. Ernst Pless join forces and create a cross-century brand - AKG.
Then in 1982, AKG launched Hi-End level light headset Series K1 - a foldable portable headphones, though it was only a very small amount of sales, but its innovative design also countless enthusiasts whom nostalgia. After,[http://www.monsterbeatsby.de/monster-beats-2012-c-2.html Monster Beats 2012], in 1984, AKG has become one of the most profitable companies in history, the AKG stocks for several years to become a favorite investment! Its most classic of a headset - K1000 is also designed in the late 1980s, and the birth At that time, the company's flagship product, is so far the highest grossing listening level headphones.
AKG K1 rare artifact in the world!
With the rise of headphones fever boom in the late 1990s, K1000 slowly flying into the homes of ordinary people, which will become a great collection collections enthusiasts today.
As a AKG's flagship product,[http://www.monsterbeatsby.de/monster-beats-turbine-c-15.html Monster Beats Turbine], K1000 fully reflect the the AKG sound aesthetic concepts,[http://www.monsterbeats-bydre.de/beats-by-dr-dre-nhl-c-16.html Beats by Dr Dre NHL], this HI-END-class reference monitor headphones AKG's approach is to do at least a compromise on the acoustic design to ensure that the headphones capable of reproducing pure dye sound. The design of the K1000,[http://www.monsterbeats-bydre.de/monster-beats-graffiti-c-4.html Monster Beats Graffiti], AKG bold rejection of the earmuffs, eliminate the "sound room" before the diaphragm, to solve the earmuffs interdiction of binaural effect.
From Hollywood, to the fans, the people are all sought after the headset
Today the most renowned of the AKG again force stationed in the Chinese market audio industry. Breath and preferences of different groups of people in the country launched a number of headset products! After nearly a century anyway, AKG now has the longest line of industry numerous audio brand worldwide. Headphones from a few hundred dollars to tens of thousands of dollars of home audio system, it can be said to cover almost all the audio equipment you want.
AKG K520 headphones frequency response range of 18 ~ 24000Hz, impedance is 32 ohms, sensitivity of 108dB. The ultra-low impedance, high sensitivity, and can easily be a variety of portable devices driven HiFi extends to every moment of life. Its excellent low-frequency performance, under a sense of the potential and the amount of aspects are great! The new design of the first beam, the purpose is to make you comfortable to wear for several hours.
AKG K520 is not only the shape is more stylish, more or less stained point "K1000 advantage of
The new AKG K840 HiFi sector's most famous Kleer lossless transmission protocol applied to them. Kleer lossless transmission protocol is based on 2.4G band again AKG algorithms coupled with perfect wireless HiFi. Wireless transmission for sound reduction is still not perfect, and make it sound wired headset almost no difference. AKG K840 and with a strong battery life up to 28 hours!
The wheel of history, although ablation sturdy stone walls, but the technology was created to give a true retention, to restore our image equipment, AKG to civilians, let each of us ordinary people, but also to have the opportunity to listen to the recorded history the most realistic sound!

Headset pure tone, the sound field is very broad, and can capture every detail of the sound field to cope with the symphony this dynamic, wide range of music aplomb, in fact, the pride in the HiFi headphones.
Beyerdynamic is a professional audio manufacturer founded in Berlin, Germany, has been the 76-year-old Austrian AKG, initially making theater audio equipment (speakers) industry. The beyerdynamic name derived from its founder Jurgen - Baia (Eugen Beyer). 1937, beyerdynamic pioneered the development of the world's first deputy Dynamic headphones DT48, has now entered the field of high-fidelity headphones. The DT48 this headset is still in production and sales can be regarded as the world's longest production history headphones. In 1939 beyerdynamic microphone field, M19 microphone to break into the German national radio. In the 1930s, this microphone widespread use of radio and television stations in Europe, laid beyerdynamic's position in the audio industry. Beyerdynamic now developed into a global enterprise, with branch offices in the United States, Britain, France, and Sennheiser, AKG, is a recognized authority in the professional headset microphone field.
The American Goethe is known as the world's four major professional HiFi headset manufacturer with the three major manufacturers. RS1 is the best dynamic headphones, bass is particularly impressive, not only a powerful and flexible, rich layering and pop fans preferred headphones.
KOSS United States headphone manufacturers, known for the production of civilian headset. A250 KOSS top dynamic headphones, warm tone, rich bass, suitable for all types of music is played.
The iron triangle of Japan's most famous fever headphone manufacturer, but also to produce video and electrical equipment. The top dynamic headphones W100 is very noble, the shell is made of Hokkaido cherry blossoms made of logs. W100 bass full amount of sense, sweet, rich vocal Petty Bourgeoisie.
