General Knowledge of Headphone And How to Choose
In the strict sense of the word, the headphone is a listening gear with rather big sound body which should be worn on the head. It is not the earplug adapted to most Walkmans. According to transduction principle, headphone can be divided into dynamic type and capacitive type. Electric principle is to make the magnetic field by currents in the coils, so that diaphragm can make sound, characterized by high sensitivity, and can withstand higher power, the sound quality is stability, with simple structure. There is no wire coils in the capacitance headphones. In general, the diaphragm is used as a movable electrode, when the diaphragm is coupled with electrical signals, due to changes in the polarity of the signal, attraction and repulsion vibration generated on the electrode point make sound. It is characterized by wide-band, excellent sound quality, but its structure is complex and the cost is high.5 Hot handbags online Mode in 2010 Spring
What kind of headphones are good? Firstly, the sound is pure and true.
No much power, less than 0.2W, is needed for the sound units. Therefore, signals from sound source don`t have to go through amplifying circuits to keep the original sound quality. Because of the application of the high-tech material, at present, it is not difficult for the headphones to acheive the full-range regeneration. The frequency indicator of slightly better headphones are better than 20-20KHZ. A lot of high level can reach 10-30KHZ. While the ditoration degree is less than 0.2 percent. It is difficult for the majority sound systems to achieve. Headphones` temporary properties are sound and great controlling ability due to its light weight. Unlike the loudspeaker which lessens the quality of the sound rebroadcast due to the influnce of the piston motion,etc,the headphone has high analysis ability, broad dynamic range, pure and natural sound,You May Pass over These When Deck with cheap bags online
It has the rich sense of space. The sound field the headphones feel is based on the head as the center to spread to the front as a sphere. While the sound field of the sound system is in front of the listeners and spreads vertically and deeply.
So when you wearing headphones sitting in the concert hall as the front of the middle, almost climbed to the position of the conductor, the whole body immersed in music. This feeling can be extraordinary!Serviceable Tricks that Deserve to Learn for Maintaining Your LED Flashlight

But it is difficult for the sound system to do this. As we all know, after the sound has been well located, there is a fixed listening position. The headphones can easily move around. You must feel pretty good at this time!
When purchasing headphone, you should pay attention to the impedance. Usually the impedance of those low-end and intermediate ones are 30-50 ohm, and those can be used directly by walkman and other devices, such as VCD,LD,CD,DVD,cassette and radio,ect. Dynamic impedance of high-end headphones for more than 300 Europe, promoting the need for a dedicated headphone amplifier can be used, such as: Singhai HD-580, HD-600's impedance is 300 Europe.
After listening to my description above, have you moved? Now action and buy one immediately. You even can not believe that the sound quality of your walkman will have such big improvement after changing headphones.
