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.

In-depth analysis of the development of the basic chip market for mainland operations, based on the three major telecommunications operators 3G services during the commercial period is less than 1 year, therefore, 2G baseband chip is still the current mainstream, the overall proportion remained at 90% level. Looking into the future, the gradual completion of the network construction, the diversification of terminal models, and the stimulation of preferential tariff plans will all boost the proportion of 3G baseband chips, which will become the growth momentum of the mainland's mobile baseband chip market.
With the number of 3G subscribers on the mainland beginning to show a leaping growth, the shipments of baseband chips have also been rapidly expanding. It is expected that the mainland 3G baseband chip market in 2010 will be expected to exceed 50 million units, bearing the momentum of rapid growth, and the overall market in 2013. The scale will look more impressive at a level of 100 million units. Based on the attractive potential business opportunities of the mainland 3G baseband chip market, not only does the 3G baseband chip maker speed up the layout, it also attracts new entrants to actively research and develop.
In terms of the strategy of product layout for 3G baseband chip manufacturers, patent issues and potential markets are naturally the primary considerations of the industry. Based on the WCDMA and CDMA2000 EV-DO patents already held by companies such as Qualcomm and Nokia, the TD-SCDMA patents dominated by the mainland are relatively decentralized. Compared with other 3G specifications, they are most likely to follow the 2G Generation GSM specifications and become 3G. Generations of mainstream cottage specifications attack the market.
Compared with TD-SCDMA specifications, there is an amazing potential market potential for domestic cottages, attracting international first-tier baseband chip makers to aggressively enter the market. The relevant industry players in the TD-SCDMA baseband chip market account for more than 3/3G users globally. 4. One-third of the WCDMA specifications of the baseband chip occupy the global market. As a whole, the three major mobile communications technologies have their own market positioning, attracting industry players to actively expand the product line.
Looking at the changes in the global action baseband chip industry, the most noteworthy is Mediatek's market share ranking first in terms of shipments, while Qualcomm's (Qualcomm) ranks with a slight margin, however, if Based on the sales value benchmark, Qualcomm’s market share far exceeds that of MediaTek. Accurately speaking, the asymmetry in shipments and sales value indicates that MediaTek specializes in low-end and high-level integration and high-level integration of the operating strategy.
