Wirless Earphone...! [Digital Technology]

Wireless Headphones

All of the above mentioned Headphones have almost unmanned versions; But for that you have to spend the extra money. If you want to use it with portable devices then they are all good. But if you are in the morning at the time of bayam; Whether you want to use it at the time of Hathahati; But you can buy it. However, it can not produce sound quality of the well-equipped headphones.

Specification

From Magnets to Wireless Technology; Headphones have some specification. We need to know this.

1 Acoustic System
In the case of the Air, Acoustic refers to the design of the AirPhone. A closed acoustic system is able to prevent external sound coming inside such as: Sony MDR-ZX110AP However, there are some open acoustic systems that allow external sounds to be heard, such as: Philips SHP9500. However, sometimes closed or closed closing acoustic systems are not very popular. Only Good Fit Acoustic Headphones are able to successfully close 100% noise.

2 Frequency Response
Frequency Response says that the frequency of air frequency can cover the airphone. As much as the Frequency range can cover, the better the sound. For example: Audio-Technica SPORT2BK, which has a frequency of 15-24,000 Hz Frequency range, is higher than the Frequency range of Sony MD-RXB50AP, so its sound quality is good.

3 Impedance
Here impedance refers to the electric signal circuit's signal signal. More Impedance means less electric signal and low sound quality. So, this is a low level of Impedance in good headphones. For example: Philips SHP2600 / 27

Magnet
Sometimes we do not focus on this magnet. Headphones are mainly made with two types of magnet: Neodymium and Ferrite. Neodynium in Sony MDR-ZX300AP / B and the power in the Ferrite model of Sony MDR-V150. Neodymium is used in everything in Mordon and is stronger than Ferrite. This magnet production can increase the cost; But do not worry too much

5 Sensitivity
The headphones are measured in this sensitivity dB / mW unit. This means that how much sound headphones can be made in 1 ml of electrical sensation. If this sensitivity is within the standard 80-110 dB,

6 Diapharagm
Diapharagm This is the headphone membrane which produces cups and words. Dome, no, horn is made in different shapes Diapharagm. The quality used in this Diapharagm is as good as the sound quality used. So the matter of Diapharagm must be kept in mind.

7 Voice Coil
The coil that is used with the headphone's magnet is called a voice coil. This coil is made of various materials. Jemam: Copper, Aluminum, Copper-Cladding Aluminum. Aluminum Copper's sound is very sensitive; However, it is not as durable as Copper Coil. So now the headphones have used Copper-Claude Aluminum COAL or CCAW.
