What is a canal phone?
Listening devices come in a variety of types: Muffs and headphones, called supra-aural devices, cover the outer ear and use small speakers to deliver sound into the opening of the ear canal. Canal phones, more commonly called earphones, (“canal” phones just sounds yucky to some people) do not cover the ear, but use tiny little devices called drivers to deliver the sound from inside the ear canal. By actually inserting the drivers into the ear canal you can get the device very close to the ear drum, thereby reducing the opportunity for distortion to get in the way of the pure sound you are seeking.
