According to the exchange principle (Transducer) consists of moving coil (Dynamic) and electrostatic (Electrostatic) Headset two categories, although in addition to the two classes are so magnetic number, but or have been eliminated or for professional use market consumption, not in the discussion.

Moving coil Headset principle: most (about 99%) of the Headset earplugs are such, principle is similar to ordinary speakers, in the permanent magnetic field in the coil is connected with the diaphragm, the coil drive the diaphragms in the signal current drive.

Electrostatic Headset: electric diaphragm is changing, diaphragm thin, accurate to a few microns (the electrostatic Headset diaphragm of a new generation of the STAX is accurate to 1.35 micron), coil driving force of the electric field driven diaphragms.

According to the size

The size Headset: English using "Ear-pad" (the ear pad? Not sure), or "Mid-Size" (medium size). Their definition is not according to the speaker caliber, but according to the ear muff size. If Headset earmuffs can not completely surrounded by ear, it belongs to the size Headset.

Full size Headset: earmuffs can completely surrounded by ear, even if is the size Headset. Known as Sennheiser HD5 6 series, is almost full size Headset uniform.

According to the shape of

According to their shape can be divided into type, open and semi open closed:

Closed Headset is through the soft pad of its own to wrap your ears, so that it is completely covered up. Such Headset because the pad is large, so the head is large, but with the pad can be used and not affected in a noisy environment.

Open Headset is Headset style popular. This kind of machine is using spongy foamed plastics production through the sound of the ear pad. It has the advantages of small volume, wearing comfortable, no longer use dye pad thick, so did not with the external world of isolation, but its low frequency loss. In the listening, the Headset or good.

Semi open Headset is integrated model Headset closed and open two Headset advantages (it was a half breed, fusion of the two Headset advantages, disadvantages improved), such Headset uses multi vibration of membrane structures, in addition to an active active vibration membrane, also have more than one passive driven diaphragm. It has low frequency and high frequency description describe a rich, natural, clear bright many, now used many of the more high-grade Headset wide is the Headset.
