HeadPhone Thai

Headphones are sort of like shoes: There&＃39;s an element of utility (different shoes for different uses); an element of comfort (heads and feet come in different sizes and shapes; a poor fit is no fun); and style (both are worn and seen by others). Each headphone type has advantages and disadvantages in sound quality and effectiveness in various modes of use. There are also some physical variations within each type, for example in the way they are secured to your head (headbands around the back of your neck, loops that go over your ears), all of which will be covered in the appropriate sections below.Headphones come in many shapes and configurations, but there are fundamentally five basic physical types of headphones, which are characterized by the size and shape of the ear-piece and how they physically interface and acoustically couple with your ears...the topic of this article. Other methods of classifying headphoneswhich will be discussed in depth in other articlesare by acoustic principle (sealed, open, noise canceling), by the type of acoustic driver used (dynamic, planar magnetic, electrostatic, etc). We can ignore driver types and noise cancelers for the moment, but it is important for the following discusion to know about the fundamental differences between open and sealed headphones.
