用苹果耳机这么久，竟不知两个小孔暗藏玄机
在每次购买一部手机时，每个手机厂商都会赠送一副自家生产的耳机。不得不说，就只有自家的标配耳机才耐用。对于耳机的音质来说，就当然少不了苹果原配的耳机EarPods。今天这一观察，原来都是暗藏玄机啊！
这款耳机是苹果自己开发的原装耳机，2012年刚刚推出就备受瞩目。至今也是苹果用户非常喜爱的耳机之一。它与老板的耳机的区别在于它的形状和佩戴起来的感觉！这款耳机的驱动模块经过苹果工程师三年的不懈努力，可以将声音的损耗降到最低，把音质发挥到极致，同时降低本身的功耗。而且这款耳机的佩戴舒适性得到了很大的提升！最厉害的是这款耳机在防水性能上走在了世界前列！这款耳机可以避免运动时产生的汗水对耳机的影响！
那么这款耳机有什么特别之处呢！如果您用的是这款耳机，或者类似形状的耳机，就会发现在耳机的下部有几个长条形的开口！那么它们的作用是什么呢？是因为这样做可以更加美观或者是节省材料降低重量？其实这款耳机本身重量就不是很大，况且这几个开口非常的小也减小不到多少重量。同时也节省不了多少材料。那么苹果工程师花费三年时间会在上面开几个没用的洞吗？答案当然不是，这几个小孔可是有大作用的！
当年老款的苹果耳机常常被人吐槽，声音太过平淡，如同白开水一般。口渴的时候非常解渴，但是喝多了就会有吐的感觉！说白了就是太平淡，低音表现一般！而这款EarPods则完全不同，各个音域的表现力都非常的出色，跟老一代前辈相比在低音方面表现力更加浑厚动听！那么苹果工程师是怎么做到的呢？其中的秘密就藏在耳机下部的几个孔上！这几个孔其实是低频导向口，这么做的好处就是耳机的低音表现力更加细腻浑厚，把之前老款耳机低音表现力不足的问题完全解决了！
而且这几个洞还是分别苹果耳机真伪的关键所在，放音乐的时候把耳机的这几个洞用手堵住，你会听到耳机里的低音部分消失了，只有高音正常，这样的耳机就是原装苹果耳机，如果声音没有任何变化那么就是假的苹果耳机！
其实，苹果的高品质从一副耳机就能够看出来。从以前的被吐槽到一步步的改进和成功，都是经过了不断的研究所达到的成效。两个不足为奇的小孔原来都是暗藏玄机。以后再也不用怕人家用假的苹果耳机糊弄自己了。
