BANGALORE: What Makes LeEcos Pioneering CDLA Technology Superior? When it comes to audio technology, the 3.5mm headphone jack is one of the older survivors.
While the audio players have changed from cassettes, CDs, MP3 to hi-fi players, the audio jack has remained all the same. It is still in the analog era where the 3.5 mm headphone jack rules the roost. Since then, the audio standard used to listen to music has been more or less the same.
The 3.5mm headphone jack tracks its origin in 19th century. It is a miniaturized version of the erstwhile quarter-inch jack (6.35mm) standard that was used by telephone switchboard operators. Its for sure that some incremental changes have taken place over the course of such a long period but the evolution was more of a cosmetic one than in substance. However, user expectation from music experience on smartphones has grown exponentially, with the growing consumption of data on-the-go.
Over the years, Walkman gave way to headphones which were lighter and made music mobile, giving way to the portable era. Since then headphones became sportier with round ear clips to stay put during exercise. Then these headphones were coated with large plastic coated cups aimed to block out noise.
