Points to ponder: What is a headphone?

Headphones (also known as earphones, stereophones, earbuds, headsets, or by the slang term face plug or scans) are a pair of little loudspeakers, or a single speaker, with a way of holding them nigh to a user's ears. And a means of connecting them to a monophonic, stereophonic, or binaural audio-frequency signal source such as radio, audio amplifier or CD player. The term headset is used to describe a combination of headphone and microphone used for two-way communication.

The listening situation and the demands of the listener will determine what type of headphone will be used. There are many different types of headphone designs, generally, headphone formfactors can be divided into four separate categories: Circumaural, earbud, supra-aural, and in-ear.

Circumaural headphones have circular or ellipsoid earpads that fit out around the ears. This class of headphone is occasionally used among audio enthusiasts and in recording studios.

Earbuds or earphones are headphones of a smaller size that are placed directly outside of the auricle canal, but without fully enveloping it. They are favored for their portability, ease, and are generally inexpensive. They are not efficient of delivering the same dynamic range provided by many full-sized headphones and canalphones for a given volume level due to their inability to provide isolation.

Supra-aural headphones have pads that pose on top of the ears rather than around them. They were occasionally bundled with personal stereos during the 1980s.

Canalphones, also known as in-ear monitors, or IEMs, are earbuds that are put in directly into the ear canal. Canalphones works as earplugs to bar out environmental noise and also offers portability similar to earbuds. There are two main types of IEMs ? custom and universal.

Decision: I have sought all kinds of earbud headphones on the internet and I learned that Panasonic RP-HV280K is the bestselling one.
