Although the question remains as to why similarly designed earpieces found in other phones (like Nokia N85 and Nokia E71) don't suffer from this effect as well?

虽然问题依然存在，为什么同样的耳机设计中找到其他的手机(如诺基亚n 85和诺基亚e71)不遭受这种效果呢？

On the other hand, we didn't experience any sound quality issues with the Nokia N85, furthermore, the earpiece that spent two weeks with it in one box didn't show any signs of creaking noises either.

另一方面，我们没有遇到任何声音质量问题与诺基亚n 85，此外，耳机的花了两个星期的同在一台设备里面没有任何迹象可以吱吱的噪音。
