Wikipedia: Headphones
Headphones are a pair of small loudspeaker drivers worn on or around the head over a user’s ears. They are electroacoustic transducers, which convert an electrical signal to a corresponding sound. Headphones let a single user listen to an audio source privately, in contrast to a loudspeaker, which emits sound into the open air for anyone nearby to hear. Headphones are also known as earspeakers, earphones or, colloquially, cans.
 
Wikipedia: Head, Shoulders, Knees and Toes
“Head, Shoulders, Knees and Toes” is a children’s song. The song was documented as early as 1961. It is often sung to the tune of “There Is a Tavern in the Town”, although it is sometimes sung to the tune of “London Bridge Is Falling Down”.

#Apple bought headphones for $3.2 billion? This bodes well for my Shoulderphones®, Kneephones® and Toesphones® company.
