    There are three types of headphone technologies:

    The first is the most common: moving coil. It’s like a miniature loudspeaker, where a surface moves forward and backward attached to a coil or bobbin that moves in the field of a magnet. It’s a lot like a dynamic mike in reverse.

    The second is “Planar Magnetic”. Where current runs through a printed circuit attached to a thin film or diaphragm. . The thin film rests in a magnetic field provided by permanent magnets. Potentially planar magnetic is much cleaner than moving coil as the diaphragm is much lighter and easier to move and more linear.

    Lastly there’s electrostatic. Check out my review at
