Q: Why are the microphone receivers in Chinese cell phones so poor?

we always hear about how China's cellphone industry is so large and strong, how it makes good cellphones. However, if this is true, it makes little sense why the receiver is of such poor quality. I don't understand. I feel bad for Chinese people who buy these phones and are forced to yell into them because they are of such poor quality.

I'll give you 3 answers to this. Make your pick which you think is most likely

 

A) In a more technical explanation. High end phones have several microphones, e.g. one by the mouth and one on the top. The two microphones will then both listen. Then to filter out background noise, the sound picked up from both gets compared, a processor determines the difference in direction of the sound based on the speed of sound and can thus filter off the background noise from the mouth facing microphone. Doing this requires processing power and higher end hardware. Generally a lot of China phones are cheap because they are using reference hardware design living up to the bare minimum of what is required. 

 

B) The phones are fine, the people are faulty. 

 

C) All the development budget was put into making a speaker that would be able to play ringtones at a volume where you don't have to be bothered if you are standing behind a jet engine.

A:Going to HK would be the best bet I reckon, especially if you were looking for a church wedding. Chinese weddings are pretty grim IMO - you go to a barren govt dept with souless officials and navigate red tape so some guy can give you a red stamp and a marriage book. You get expensive pictures taken of you both posing in places you'd never go to in everyday life that is somehow supposed to represent your wedding, then a while later it's off to a restaurant where a game show host kind of guy makes sure it's as tacky as possible while the guests eat as fast as they can so they can leave as soon as they finish eating and gave you money. Hell, I'd go to Thailand or the Philippines and get married in Paradise.   -- Stiggs
