Strictly speaking, headphone is a kind of listening device in the head with larger pronounced body, and it is not the earplugs used by the vast majority of Walkman. Expert shopping Trend Bible: Flashlights According to the transducer principle, headphones can be divided into two categories: electric (dynamic type) and capacitance (electrostatic type). 10 Most Fitting Giveaways: auto accessories The theory of the electrodynamic type is to get the beryllium pronounce by forcing the electricity through the coil in magnetic field, which has high sensitivity, stable tone quality, simple structure and can bear relatively large power. Whereas the capacitive headphone is free of loops, and it takes diaphragms as its anodes. When the diaphragms are added by electronic signals, sound will be get due to the attractive and repulsive vibration in the anodes caused by changed polarity of the signals. It is characterized by wide-band, excellent sound quality, but its structure is complex and the cost is high.This Year, People all Love Electronic Gadgets

• Why is headphone good? The first reason is its true and clear tone.

The sounding units of the headphones do not require high power, usually not more than 0.2W. Therefore, the sound can be kept just as the original sound source saving amplifying the circuit step by step. Thanks to the application of high-tech material recently, it is not difficult to regenerate the gamut. The frequency response standards of most relatively good headphones are better than 20-20KHZ and many superior ones even can reach 10-30KHZ and keep the degree of distortion lower than 0.2% which is rather difficult to achieve for most of the sound systems. As the quality of the small diaphragm headphones, so the transient characteristics are also very good, control is also strong, Unlike the speaker, it is affected by the movement of piston to reduce the sound quality. The headphones have high resolving power and large dynamic range and naturally pure voice.The Misunderstanding of ipod nano case You Should Know

• It is full of spatial impression. The sound stage that headphone feels is centered with head and spread forward in a shape of sphere, while the sound field of sound system spreads in front of listener then in depth.

Therefore, headphones may give you a feeling of sitting in the center of the front row or even in the position taken by the band director. Immersing yourself in music, you will feel extremely good.

• Accurate sense of direction. There is only one pronunciation point in the headphone, which can accurately restore the stereo audio orientation treatment of the various musical instruments carried out by sound engineers, representing the band’s sound in different directions.

In contrast, the sound system can hardly achieve this effect. As we know, we the stereo is arranged at a fixed place, you will feel good when moving randomly with the fixed postion of listening to the sound.

When purchasing headphone, you should take care of one technological index which is its impedance. As usual, the impedance of low or middle grade of headphone is between 30 and 50, which can be adapted directly to Walkman and other equipments like VCD, LD, CD, DVD, Cassettes, Radio and so on. Whereas to the high-quality headphones, the resistance of the movable coils of the headphone should be 300 ohm or more, and therefore, it can be only used with support of earphone-function. For example, the resistance of SENNHEISER HD-580 and HD-600 is 300 ohm.

Are you temped? Actions speak louder than intentions. Hurry up and buy yourself such a headphone! You may even not believe, after the change of headphones, there will be such a big improvement of your walkman in sound quality.
