Title: To rate Earphone Brands
Objective: To understand the people’s view on 4 speaker brands.
Introduction: Earphones 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. Earphones 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. Earphones are also known as ear speakers, Headphones or, colloquially, cans.
