Headphones : driver types

Dynamic

Dynamic drivers use magnetic material attached to a diaphragm that oscillates back and forth. This is the most common type of driver used in headphones.

Electrostatic

A thin mylar sheet is between two metal plates and a charge imbalance on the plates vibrates the mylar sheet, producing a diaphragm. Examples of electrostatic headphones are the Stax SR-007 Omega II, and the Sennheiser HE90 "Orpheus".

Balanced armature

Usually used only in canalphones such as sensaphonics.
