Points to ponder: What is a headphone?

Headphones (also known as earphones, stereophones, earbuds, headsets, or by the jargon term face plug or scans) are a pair of little loudspeakers, or a single speaker, with a way of holding them near 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 portray a combination of headphone and microphone used for two-way communication.

The listening attitude and the demands of the listener will decide what type of headphone will be used. There are various different types of headphone designs, generally, headphone formfactors can be split up into four separate classes: Circumaural, earbud, supra-aural, and in-ear.

Circumaural headphones have spherical or ellipsoid earpads that fit out around the ears. This kind 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 incapability to provide isolation.

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

Canalphones, also recognized as in-ear monitors, or IEMs, are earbuds that are inserted directly into the ear canal. Canalphones acts as earplugs to block out environmental noise and also offers portability similar to earbuds. There are two primary types of IEMs – custom and universal.

Conclusion: I have looked all kinds of earbud headphones on the internet and I found out that Panasonic RP-HV280K is the popular one.
