Technical Information: Headphones

In choosing/buying a product is very common in faced with information that we can’t understand. Come to think of it, the Cenetel decided to clarify for you, in this article, some important concepts about headphones:

Connector:Is the output of the phone. It is important to pay attention to the format, because the compatibility sets if you have to relate the two, in this case, the phone and the mp3/computer. P2 is the common format for audio input, and P3 for headsets with microphones, i.e. that have audio output.

 

Driver:Is the set of parts and circuits that are inside of the armor of the phone and are measured in millimeters. Headset small ear carry smaller drivers, and, consequently, the materials used need to be miniaturized. This can increase the cost of the device. Already the supra headsets do not face this problem – until it is possible to affirm that larger drivers mean better quality of bass-, but lose points in terms of convenience.

 

Impedance:Refers to the propagation of a sound from a given environment to another, incorporating different characteristics. Expressed in Ohm (unit of electric resistance), the impedance maintains a ratio inversely proportional to the volume of the music: between the lower the impedance, the higher the volume.

 

Frequency response:The human being is able to perceive frequencies between 20 Hz to 20,000 Hz. A phone can play the sound in this common frequency range. However, there are professional models who can produce the sound out of this frequency range, intended for people with acute acoustic detection capabilities.
