Airline Headphones
Aviation headphones are used in airplanes, cars, subways, etc., to facilitate passengers to listen to audio and watch videos to enjoy a pleasant journey.
The aviation earphones are mostly disposable, so the structure is extremely simple, the shape is relatively ordinary, the materials are small, and the annual usage is very large. The number of inquiry can reach several million or even tens of millions, so the cost is very cheap. earphones can cost as little as 10-15 cents. Therefore, they are disposed of as garbage after used, and passengers could take it away for personal use.
Styles can be divided into on ear headphones and in ear earphones.
Functional difference: power, impedance, and sensitivity etc. are also different. Airplane Headphone is mainly customized according to the equipment, place and user used. For example, 1 customer might require 300 ohms impedances , and other customers may need 32 ohms. For adults, the sensitivity may reach 100DB or more.To children, the sensitivity may be around 85-90 DB.
In addition, aviation headphones are not all disposable ones. Some first-class cabins need to be equipped with headphones with good noise reduction, sound quality and functions. So the price will be much more expensive.
